1906 Locations

Notes on Locating and Assigning Intensities to the Shaking and Damage Descriptions in Lawson (1908)

These footnotes describe how the damage and shaking reports from Lawson (1908) and other sources were used to assign MMI intensities at specific sites. The difficulties of locating the more obscure sites are also indicated. About 60% of the sites are footnoted. The spreadsheet containing the site names, locations, soil-types, page numbers in Lawson (1908), our assigned MMI intensities, a grade for the intensity, and Toppozada and Parke's (1982) MMI intensities can be downloaded.

1. G.A. Waring reports “Near Agenda, in the lowlands, is a cracked area nearly a mile from the river, probably along an old water course; while sand craterlets are scattered through the orchards.” We assigned MMI 7-8. Three miles northwest, “At Spreckels, the movement caused much damage to flumes, sewers, and water-mains,” as well as strongly damaging the 5-story sugar mill. We assigned MMI 8.

2. Agnew State Hospital was one of the most famous wrecks of the 1906 earthquake. 117 inmates and staff were killed when the floors failed, and poor workmanship was widely alleged as a cause. We assigned MMI 8.

3. In Alameda, the majority of the destruction “was confined to … the throw of chimneys and the upper portions of brick walls.” A total of 619 chimneys fell throughout the city. The large chimney at the oil works collapsed, in addition to the roof of a two story building on Park Street. We assigned MMI 7-8.

4. The Alameda County Hospital at Fairmont is called "the County Hospital." It was only slightly damaged; no chimneys were thrown down. We assigned MMI 6.

5. At Albion, James Coyle "was thrown violently to the ground, as were several cattle and horses that were grazing nearby. Large rocks were seemingly squeezed out of the hillside and rolled into the river. Many houses and bridges were thrown down." We assigned MMI 8-9.

6. On Alcatraz Island, “A heavy shock was felt… Objects were overturned in every direction.” We assigned MMI 6.

7. F.E. Matthes reports that “the wagon bridge over Alder Creek, which stood astride of the fault, is a complete wreck. The timbers broke in many places, and the tension rods were twisted and in some cases actually ruptured.” Rock slides and ground cracks were abundant from Alder Creek to Irish Gulch. We assigned MMI 9.

8. Alexander Valley was the site of a bridge across the Russian River that was wrecked by the earthquake. There was extensive cracking on the eastern bank. We assigned MMI 8.

9. Alma and Lexington were inundated by the Lexington Reservoir. There was a large landslide at Alma. We assigned MMI 8-9.

10. The 1896 Post Office map locates the Altruria Post Office north of Santa Rosa, on the road to Mark West Springs. R.S. Holway reports "cracks are said to have opened in the road, and springs to have flowed for a short time." We assigned MMI 7. A mile west, at Fulton Road, D. Butler notes that the damage was very slight. We assigned MMI 6-7.

11. The Alum Rock Hotel was located near the present Visitors Center for Alum Rock Park: "no chimneys were damaged nor had any movable objects been overturned." We assigned MMI 6.

12. The Alameda Sugar Company suffered the most damage in Alvarado. “A 6-inch cast-iron water pipe…broke transversely about 30 feet above the ground,” and the two platforms supporting the molasses tanks fell altogether, resulting in damage to the tanks and the release of more than 1,000,000 pounds of molasses. Nearly all brick chimneys in the village fell. We assigned MMI 8.

13. Alviso suffered fallen chimneys, broken cornices, and cracked walls. “Little serious damage of any kind was to be noted.” There was extensive cracking and settlement in the area between Alviso and Milpitas. We assigned MMI 7.

14. At Andersonia, the Ukiah Dispatch-Democrat reports “Chimneys were tumbled down, ... The earth has many wide fissures … Tops of trees were shaken off, slides were thrown into Eel River, Indian Creek and along Southern Humboldt Lumber Co.’s railroad so that extensive repairs are necessary. The Southern Humboldt Lumber Co.’s dam is also damaged as well as telephone lines and mill. We assigned MMI 8.

15. G.W. Fiscus reports that the damage in Annapolis was widespread. Many buildings and bridges were wrecked, in addition to landslides and the destruction of chimneys. The waters of the Gualala River were thrown out 50 and 60 feet. We assigned MMI 9.

16. In Antioch, E.S. Larsen reports that “about 25 percent [of the chimneys] needed repairing” and that “out of about 12 brick buildings, the tower of the Catholic Church was somewhat damaged, and one rickety old brick building fell. None of the good buildings were damaged.” We assigned MMI 7.

17. The Watsonville Pajaronian reports that “the bluff near Aptos is badly cracked” and a chimney fell through the roof of a summer home. G.A. Waring reports the wagon and railroad bridges as undamaged. We assigned MMI 7. The Day Valley Cemetery, located 0.6 miles north of the Watsonville Road, suffered moderate damage. We assigned MMI 8.

18. The Arcata Union reports that “nearly 30 chimneys were toppled off” in the lower part of Arcata, and that the Union Hotel was “strained.” Neither the Arcata Union nor the Blue Lake Advocate mention the fissure that Lawson report claims “opened in one of the streets … but by night it had closed again.” We assigned MMI 7.

19. The Watsonville Pajaronian reports that “the buildings on Stony Ford Ranch at Aromas … have been thrown down, and the railroad track buried under rock hurled from the quarry.” We assigned MMI 8-9.

20. Baden Station was incorporated into South San Francisco.

21. Bald Hills Post Office was renamed Elder Post Office in 1874.

22. The intensities for Bald Hills, Hower's, Martin's Ferry, Weitchpec, Orleans, Somes Bar, Forks of the Salmon, Gilta Mine, and Brook Mine were obtained from interviews conducted by a medical examiner, Mr. P.L. Young, who only described the earthquake as either “felt” or “heavy.”

23. In Bartlett Springs, “nothing … was reported as having been knocked over, nor was any milk spilt from pans.” We assigned MMI 5.

24. In Bear Valley (San Benito County), "the only noticeable effects ... were the swinging of lamps and the disturbance of water surfaces." We assigned MMI 4-5.

25. G.K. Gilbert reports topped spruces in Bear Valley on Point Reyes, with 1/2 mile of the fault. Some summer cottages sustained little damage other than fallen chimneys, but a barn was wrecked. We assigned MMI 8-9.

26. Beckwourth was renamed "Beckwith" by the US Post Office. The Beckwourth Trail was discovered by Jim Beckwourth in 1850 and led from Reno through the Beckwourth Pass to the town of Beckwourth, and then to Quincy and Marysville.

27. Bell’s Station was located 6 miles west of Pacheco Pass. “No damage was done beyond the loss of milk. High bottles and dishes standing upon shelves were uninjured.” We assigned MMI 5.

28. Bellvale is called "Bellville" by S. Taber: it was a Post Office on the road between La Honda and San Gregorio. There was a substantial landslide that blocked the road. We assigned MMI 8.

29. A majority of the chimneys fell in Belmont, and “there were small landslides along the road leading from Belmont to Crystal Springs Lake…In the foothills between Belmont and San Mateo, the brick building of the Crocker Orphanage was completely ruined.” We assigned MMI 7-8.

30. In Benicia, T.J.J. See reports that two or three houses collapsed and more than half of the city’s chimneys were thrown down. At the entrance to the Arsenal grounds, the Gate House (a round tower 12 feet in diameter, constructed of brick on a solid foundation) suffered severe cracks in its walls. We assigned MMI 8.

31. Bennett Valley lies to the southeast of Santa Rosa. Only an "occasional chimney" was damaged. We assigned MMI 6-7.

32. The 1896 Post Office map locates Berdan Post Office between Forest Ranch and West Branch, but east of Cohasset.

33. In Berkeley, A.C. Lawson reports that “a large majority of brick chimneys were broken or overthrown, … several brick buildings had their upper walls thrown down.” However, “the buildings on the University Campus … sustained no serious damage.” We assigned MMI 7-8.

34. In Berryessa Valley, “The shock is reported to have been quite heavy on the level land of the valley-bottom.” We assigned MMI 6-7.

35. A sawmill owner reported that there were no landslides on the road between the Big Basin and Boulder Creek and that he had seen only one crack where the earth had begun to slide. A separate report states that near the junction of the road leading from Boulder Creek into the Big Basin, an old landslide from the previous winter had been widened by the shock and its direction had changed. We assigned MMI 7.

36. W.A. Chalfant reports an "unusual" but "untimed" length of shaking in Bishop. Doors and windows were rattled. We assigned MMI 3-4.

37. Black Diamond and Cornwall were incorporated into Pittsburg.

38. Blacks Station was renamed Zamora.

39. At Bloomfield, brick buildings were wrecked and every chimney but one thrown down. Several frame buildings were shifted on their foundations. 80% of the larger stones in the cemetery fell. We assigned MMI 9.

40. The Blue Lake Advocate reports that the earthquake damaged 15 chimneys and cracked the plaster in many houses in Blue Lake. We assigned MMI 6-7.

41. In Bodega, all chimneys were thrown down and several houses were shifted on their foundations. A mile from town, a brick bark-drier was thrown into a heap, despite the brickwork being bound together with iron rods. We assigned MMI 8. The Bodega cemetery, situated on a hillside 0.3 miles south of town, was severely damaged. We assigned MMI 9.

42. The shock was perceptible in Bodie and some clocks stopped. We assigned MMI 2.

43. In Bolinas, much of the land was broken into blocks that have been faulted and tilted. “The upper part of the village of Bolinas lies in a curving fault-sag among these dislocated blocks … in the fault-sag, where the ground was much cracked, nearly all the houses were either shifted or thrown from their foundations.” We assigned MMI 9.

44. H.W. Fairbanks reports that Boonville suffered no damage other than the collapse of “about half the chimneys.” L. Romer remembers “the bricks on the fireplace shaking loose and hitting the roof.” The Evergreen Cemetery, 1.5 miles north of town, was slightly damaged. We assigned MMI 7.

45. B. Bryan reports “in the town of Boulder Creek, all chimneys were down except those on some 1-story cottages; these were cracked, however… and plaster was cracked everywhere.” L.E. Titus, a young schoolteacher at the time of the earthquake, remembers that many of the town’s buildings “were twisted and unsettled from their slight foundations.” We assigned MMI 8.

46. The descriptions of effects at Boyes Hot Spring, Ceres, Esparto, Jamesan, the Pinnacles, and Thorn Junction are inadequate for assigning intensities.

47. J.M. Branscomb reported that 2 of 15 chimneys were “shaken down” in the vicinity of Branscomb. The Willits News reports that the earthquake caused a “dry shower of limbs and tree tops and the earth is cracked in several places.” We assigned MMI 6-7. B. Barnwell reports that the shaking 6 miles west on Branscomb Road threw down horses and cattle standing on a hillside. We assigned MMI 8.

48. The Blue Lake Advocate reports that “Briceland was more badly shaken up than Garberville. J.G. Bowden’s store and Ben Harris’ hotel were both moved from their foundations, … J.P. Cannon’s house was wrecked badly and every breakable thing in the rooms were destroyed; even the large range stove was broken to pieces.” We assigned MMI 8-9.

49. Most of the farms in Bridgeport were damaged by the earthquake: a large landslide extended 150 feet into the cultivated fields, and “a fissure at its foot was traceable for over three miles.” A. Schafer describes how the shock “rolled her bed across the room” and separated the house where the stairs were. We assigned MMI 8-9.

50. The Blue Lake Advocate reports that “the earthquake at Bridgeville did no serious damage …[but] the family of George W. Cooper … were obliged to cook their morning meal by a campfire outside the house, as their dwelling was minus chimney.” We assigned MMI 6-7.

51. Brook Mine is called "Brooks" by C.H. Johnson. Brook and Gilta were active mines in the Trinity Alps: however, the felt reports from these sites are secondhand. P.L. Young describes the shaking at Brook as "heavy," which would make it the only mine with MMI 6. We excluded this intensity.

52. "In Brown's, Los Muertos, and Quien Sabe Valleys, the shock was only sufficient to throw cream from pans of milk." We assigned MMI 5 to each of these sites.

53. In Burlingame, many poles along the line of the electric railway from San Mateo northward were altered from their previously vertical positions. Many of the houses in the Burlingame vicinity “were badly wrecked, due to the falling of extra heavy chimneys through the roofs,” and most brick walls fell unless they were well built. We assigned MMI 8.

54. The Contra Costa Gazette reports “The chimney inspection is closed in the Byron district: 119 dwellings were visited by the inspector, aggregating 175 fire flues with only 4 condemned.” In Byron Hot Springs, “One chimney and some plaster were cracked and a picture was thrown from the wall.” We assigned MMI 6.

55. Calaveras Valley was inundated by the Calaveras Reservoir: "all the brick chimneys were thrown down, tho there were only a few ...No damage to houses is reported." We assigned MMI 7.

56. C.E. Weaver reports that in Calistoga, “a large number of chimneys and 2 brick buildings were thrown down… A few local slides on the south side of Mount St Helena were confined to the alluvium.” D. Patten reports “a large rock was thrown down from cliffs up on the mountain … at an elevation of 4,000 feet on the northeast side.” We assigned MMI 8.

57. G.A. Waring reports “The intensity of the shock diminished uniformly from Meridian toward Campbell. At Campbell, 68 per cent (51 out of 89) of the chimneys fell, but the plastering in the houses was not badly injured.” We assigned MMI 7.

58. Candelaria was an active mining area in western Nevada.

59. The Cantara Post Office was located on the north side of the Cantara Railroad Bridge over the Upper Sacramento River, the site of a derailment and chemical spill in 1991.

60. Cantua Creek was crossed by an extensive landslide. The association with the 1906 earthquake rests on the observation of S.C. Lillis, who did not see the landslide occur, and G.D. Louderback's characterization of the landslide face as “fresh”. We assigned MMI 6-7.

61. The brick foundations and water cisterns at the Cape Mendocino Light Station were broken. We assigned MMI 8-9. The largest landslide triggered by the earthquake occurred at Cape Fortunas, 6 miles NNE. F.E. Matthes described it as an earth-slump and concluded “It probably had long been imminent before the earthquake started it.” We assigned MMI 8. The Blue Lake Advocate reports that “Capetown escaped with scarcely more serious results than a lively shaking up.” We assumed this report disregards chimney damage and assigned MMI 7-8.

62. “Nearly all the chimneys at Capitola fell, and considerable plaster was shaken from the north walls of the first floor of the hotel…Much earth fell from bluffs near the town, but there was no appreciable effect on the surf.” The railroad trestle, a new steel structure, was also reported to be unsafe. We assigned MMI 7-8.

63. In Caspar, the majority of the wooden houses suffered no damage, and the lumber company’s brick store sustained a few minor cracks. The bridge over the Caspar River and the trestle over Jughandle Creek, however, were both demolished and “all chimneys were broken without exception.” We assigned MMI 8.

64. The Watsonville Pajaronian reports that four homes in the Casserly School District were severely damaged. We assigned MMI 8-9. On nearby Green Valley Road, “a bunk house was shaken from its foundation.” We assigned MMI 8.

65. The earthquake did not seriously affect Castroville: only three out of approximately thirty chimneys fell. We assigned MMI 6-7. At Neponset, 3 miles southwest, both the wagon bridge and the railroad bridge across the Salinas River were damaged. We assigned MMI 7-8.

66. “At Cazadero the shock was severe and chimneys were generally thrown, but no buildings were wrecked, all the structures being of wood… Some pictures hanging against walls were turned around so as to face the walls.” We assigned MMI 8.

67. Centerville and Decoto were both incorporated into Fremont. All the brick houses in Centerville were severely damaged and many of the walls were thrown down. Some of the walls the bank building fell and the roof caved in. The brick and tile chimneys were thrown with few exceptions, and the window panes of many stores broke as well. We assigned MMI 8. Only chimneys were damaged in Decoto. We assigned MMI 7.

68. In Central San Joaquin County, "no objects or chimneys were overthrown. Windows and window weights rattled. Paper on the walls was cracked. The roof on a high church tower was cracked ... large trees swayed and bent as if rocked by a terrible gale." The township and range for this site locates it just northeast of Stockton. We assigned MMI 5-6.

69. The railroad yard at Chittenden was severely damaged. “The cottage of the foreman was moved 5 inches westward; an upright piano was thrown northwestward upon its back, and electric drop lights swung so as to break against the ceiling.” The porch of the railroad office was ripped off and a 1,000 pound safe was knocked over. Many freight cars were thrown off the tracks, and between Chittenden and the Pajaro Bridge “the track was bent in an S-shaped curve in several places.” We assigned MMI 8-9.

70. Cienega and Paicines occupy separate valleys in "La Cienega de los Paicines." G.A. Waring reports the shaking to be stronger at Paicines (MMI 6) than at Cienega (MMI 5). Four miles SW of Paicines, a man saw "a wave coming westward thru a grainfield, and some oaks waving considerably."

71. All of the brick chimneys in Cleone fell. Additionally, “all sway-braces on the wharf had to be replaced, and the railroad track was buckled in many places. The bridge across the lagoon sank 3 feet in some places, and was thrown out of line laterally.” We assigned MMI 8.

72. R.S. Holway reports that in Cloverdale, the upper walls of a brick building had cracked so as to require rebuilding, but that a different two-story brick building only exhibited cracked plastering. The inspector condemned four-fifths of the town’s chimneys, but many agree that not more than one-fourth fell. One man recounted seeing distinct waves in the ground. We assigned MMI 7.

73. In Coalinga, the walls of a few brick buildings were slightly damaged, and the brick lining of the furnace at an oil pumping station cracked. Although the oil wells and pipelines were not damaged, considerable oil was thrown from the tanks. We assigned MMI 6.

74. The largest building in Collinsville, a hotel built on pilings, was completely destroyed, and the chimneys and water-tanks were overthrown. We assigned MMI 8.

75. Over 75% of the monuments in the Holy Cross Cemetery at Colma were thrown down or "twisted on their base." Both the Holy Cross train station and the Cypress Lawn building were damaged. The other cemeteries in Colma were less severely damaged. We assigned MMI 8.

76. The only brick building in Concord was badly cracked. Most of the chimneys had also cracked, and fifty per cent of the chimneys had fallen, including a large chimney at a bakery. We assigned MMI 7.

77. Congress Springs was incorporated into Saratoga. A stone barn was thrown down, and people in houses were knocked down trying to get out of doors. Chimneys and poorly built foundations fell. We assigned MMI 8-9.

78. Cooley's Landing was near the western end of the Dunbarton Bridge. "No damage but broken chimneys was noticeable ...One house on a poor foundation was knocked down." We assigned MMI 7-8.

79. Copeland Creek runs through present Rohnert Park. R.S. Holway reports "chimneys were much more damaged than on the road ... northward to Santa Rosa. " We assigned MMI 7.

80. The Santa Cruz Sentinel reports that in Corralitos, both the Christian and Methodist churches were considerably damaged, along with two houses and a winery. An elderly woman died of “a stroke of apoplexy brought on by the fright caused by the earthquake.” We assigned MMI 8. Above Corralitos, an extensive landslide in Eureka Canyon dammed Corralitos Creek and blocked the county road. We assigned MMI 8-9.

81. At Corte Madera "huge masses of rock had been thrown down" onto Alpine Road. We assigned MMI 8-9.

82. C.L. Jeffrey describes the motion at Cotati as "objects were thrown southeast; hanging objects swung northeast and southwest" but does not mention damage to chimneys or buildings. Drury Butler describes a transit from Santa Rosa to the Copeland district school, then Cotati, and the Durham district school, where "in the valley the chimneys were as a rule thrown down." We assigned MMI 7.

83. In Covelo, the earthquake jarred objects from shelves and broke an unsecured window, but did not damage any chimneys. B.L. Reed describes the shaking in Covelo as heavy. We assigned MMI 6.

84. At Crow’s Landing, three out of eighteen chimneys fell and “considerable water was thrown from the tanks.” The walls of a brick pumping station four miles north of Crow’s Landing were cracked. We assigned MMI 6-7.

85. Cuesta is called "Guesta" by G.A. Waring: it was located along the railroad north of Cuesta Pass and San Luis Obispo.

86. Davis Mill became Jenner. The earthquake threw down chimneys and damaged trestles on logging railroads. We assigned MMI 8.

87. Davisville was shortened to Davis. "Some plaster was cracked and doors were jammed so they required resetting." We assigned MMI 5-6.

88. J. Snider was part of a road crew repairing the Laytonville Road, 1.5 miles south of Dos Rios. He describes the shaking as strong, straining a barn where the crew was sleeping and knocking down a large tree limb. We assigned MMI 7.

89. Dove was located along the railroad just southeast of Atascadero.

90. Drews Valley was inundated by Drews Reservoir.

91. The damage in Dublin consisted of a few broken chimneys and shifted water tanks, one of which fell from its supports. We assigned MMI 6-7.

92. Dudley Station was located near the mouth of Cottonwood Canyon on present CA 41. "Nothing on the shelves was disturbed, nor had milk or water slopt over." We assigned MMI 3-4.

93. At Duncan’s Mills, a large hotel was completely ruined and several houses were thrown from their foundations. J. Parmeter reports that the earthquake forced up large trees that had been buried in the bed of the river, while previously visible trees disappeared from sight, and “between the river and the ruined hotel at Duncan’s is an irregular crack about 20 feet wide, 80 feet long, and 1.5 to 4 feet deep…” We assigned MMI 8-9.

94. Dungan’s Ferry was on the north shore of the Eel River west of Fernbridge, where an extensive lateral spread wrecked a field. Similar lateral spreads occurred at Port Kenyon, Cock Robin Island, and Cannibal Island. We assigned MMI 7-8.

95. The shock at Edenvale was fairly strong, as shown by the damage done to a brick canning factory. “All the walls were badly cracked and the tops of the walls fell. The top of the fire-wall above the roof was shaken down.” We assigned MMI 8.

96. At El Jarro Point, “the shock was so light that a small chimney with a terra-cotta top, making a height of seven feet above the roof, did not fall…Glasses and bottles remained on the shelves in a bar-room.” We assigned MMI 5-6.

97. Milk was thrown from pans a few miles north but not at Elkhorn Roadhouse. We used Elkhorn Ranch to locate this site and assigned MMI 4-5.

98. Elmhurst and Fitchburg were incorporated into Oakland. Most of the chimneys fell at both sites, but no structural damage was reported. We assigned MMI 7.

99. The 1896 Post Office Map locates Emmett Station 9 miles southeast of Paicines. "Milk was thrown out in small quantities, but no movable objects were upset or moved." We assigned MMI 5.

100. Esmeralda is called "Esmerelda." It was an active gold mine in Calaveras County.

101. In Eureka, “many chimneys toppled over and several hundred panes of glass were broken… The statue of Minerva on the dome of the court house tipt toward the south until it leaned at an angle of 43°.” While one frame building moved twelve inches, no cracks were caused in any of the brick buildings. The railroad bed sank at various points between Samoa and Arcata. We assigned MMI 7.

102. The felt report for Eureka NV is problematic. In his introduction to the section “East of the Sierra Nevada,” G.D. Louderback asserts that Winnemucca was the furthest point east at which the earthquake was perceived. This would appear to preclude locating the Clay Simms report at Eureka, NV, as it is 93 miles east of Winnemucca. Lawson, however, includes the report, drawing the boundary of the Rossi-Forel Intensity II area in Map 23 through Eureka. We conclude that Simms’ letter was appropriately postmarked, but follow Stover and Coffman (1993) and disregard his report: first, because the earthquake was not felt in Tonopah, Gold Field, or Fairview, and second, because the reported duration (“it seemed to last about a second”) is entirely unlikely at this distance.

103. “At Evergreen…all the chimneys, all the road tanks, and nearly all of the wind-mills in the neighborhood fell. None of the houses were demolished, but some were shifted on their foundations.” We assigned MMI 8.

104. G.K. Gilbert reports that the towns from Sausalito to Fairfax “showed no damage more serious than the loss of a portion of the chimneys…In San Anselmo most of the brick chimneys were broken, but other injuries in that town and in Fairfax appear to have been slight.” We assigned MMI 7 to Ross, Fairfax, and San Anselmo.

105. Fairoaks (San Mateo) was renamed Atherton. It suffered broken chimneys and a collapsed (frame) bungalow. We assigned MMI 8.

106. Fairoaks (Sacramento) was incorporated into Citrus Heights.

107. Fairview is not indicated on Map 23. The Fairview mining district in Churchill County, near the 1954 Fairview Peak earthquake, gives the best geographic fit to G.D. Louderback's enumeration, out of four candidate mining districts in Nevada (see map of Nevada sites). Fairview did not feel the earthquake.

108. Two rockslides occurred on the western end of southeast Farallon Island. The Weather Bureau building was slightly damaged. We assigned MMI 7.

109. Ferndale was strongly damaged by the earthquake, but most of the damage was done to chimneys, storefronts, and two brick buildings. One frame house was shifted on its foundation. There was substantial liquefaction and lateral spreading throughout the Eel River Valley. We assigned MMI 8.

110. The Blue Lake Advocate reports that the Vance Dairy Farm in Fieldbrook was strongly shaken, but not damaged. We assigned MMI 6.

111. Fields Landing had an extensive lateral spread. We assigned MMI 7-8.

112. J.F. McNamee describes the shaking in Fishrock as strong, but his house was not damaged. The Fishrock cemetery was moderately damaged. We assigned MMI 8.

113. Forestville lost most of its chimneys. Clara Van Keppel remembers barrels of wine breaking in a winery, and the wine spilling out into the streets. A. Ross reports a ground crack in his orchard that took several years to close. The cemetery suffered moderate damage. We assigned MMI 7-8.

114. Fort Bragg was severely damaged. F.E. Matthes reports “Several brick buildings were completely demolished; others had parts of the walls broken off. Even a number of wooden buildings collapsed or were partly wrecked. Fire broke out and devastated 1½ blocks before it could be controlled.” We assigned MMI 9.

115. In Fort Ross, “chimney tops were thrown off, some chimneys being shattered to the bottom. Many redwood and pine trees were broken off, some at the ground, being uprooted; but generally broken about halfway up.” Most buildings withstood the shock with minimal damage, except “the old Russian Church and several other buildings suffered through collapse of their underpinning…and a few frame buildings set upon unbraced posts were shaken down.” We assigned MMI 9.

116. In Fortuna, store windows were broken, merchandise tossed off shelves, furniture dislodged, and over half of the town’s chimneys thrown down. “Several houses moved 1 to 3 inches off their foundations [and] the river water swashed up on the banks.” We assigned MMI 7-8.

117. The earthquake’s effects in Fresno included “a general awakening of sleepers, oscillation of chandeliers, stopping of clocks, and considerable agitation of trees…water in troughs was spilt out.” The swaying of buildings was also reported, but this motion only disturbed items without displacing them and damaged walls slightly. We assigned MMI 5-6.

118. The Blue Lake Advocate reports that in Garberville, “only a few houses moved from their foundations a few inches, … Chimneys were shaken off the houses, and every fireplace was completely demolished.” We assigned MMI 8.

119. F.E. Matthes reports that the buildings at the Garcia Hot Springs 6 miles east of the fault “suffered but slight damage.” We assumed these buildings were cabins and assigned MMI 7-8.

120. In Geyserville, “several brick buildings were badly cracked and tops of fire walls thrown down…half or more of the chimneys were reported down.” Neither the cemetery nor the nearby bridge across the Russian River was damaged. We assigned MMI 7-8.

121. In Gilroy, "nearly every chimney fell, fire-walls of brick buildings were thrown down." Monuments in both the Masons and Odd Fellows cemetery and the Catholic cemetery fell. We assigned MMI 8.

122. The majority of chimneys in Glen Ellen were thrown down, and “one wall of a brick building whose braces had been removed to make room for a stairway was much cracked.” We assigned MMI 7-8.

123. R.M. Hathaway reports from Graton, “a place 3 miles northwest of Sebastopol,” that many frame buildings were thrown from their foundations. The nearby Gilliam and Grass Valley cemeteries show substantial damage. We assigned MMI 8-9.

124. The Watsonville Pajaronian reports that a Southern Pacific warehouse at Graves was “shaken to the ground.” We assumed that the building was unreinforced and assigned MMI 7-8.

125. Grayson suffered little damage as a result of the earthquake, the only noticeable effects being a few items tossed off of shelves. No chimneys were thrown down. We assigned MMI 6.

126. Greenwood was renamed Elk. F.E. Matthes reports “weak underpinning caused the partial collapse of several frame houses. Chimneys had fallen without exception. Plaster fell in the lower stories of the few houses containing plaster. The lumber mill was not damaged.” We assigned MMI 8-9.

127. F.E. Matthes reports that “the wagon bridge over the Gualala River was seriouosly damaged… all chimneys broke off; plaster was cracked in the hotel and several other buildings; a few small dwellings were thrown off their underpinnings.” We assigned MMI 8-9. In Gualala Valley, along the fault trace, “the destruction was notably severe…” We assigned MMI 9.

128. R.S. Holway reports that all brick buildings were badly wrecked in Guerneville, and that “chimneys generally fell.” The Commercial Hotel, a frame building, was twisted slightly, and at the cemetery, one monument fell and three or four others were shifted. We assigned MMI 8.

129. Guth Landing was located near the present Shoreline Amphitheatre. Chimneys were thrown down, and a brick warehouse was damaged. We assigned MMI 7.
