A reconnaissance study of the Ketchikan area in southeastern Alaska is part of a program to evaluate earthquake and other geologic hazards in most of the larger Alaska coastal communities. These evaluations in the Ketchikan area should provide broad guidelines useful in city and land-use planning.</p><p>Ketchikan, which had a population of approximately 7,000 in 1970, is built on the southwestern end of Revillagigedo Island along the northeastern coastline of Tongass Narrows. Altitudes reach 1,000 feet (305 m) within half a mile (0.8 km) of the coast and near-vertical cliffs characterize the terrain in places. The climate is predominantly marine. Average precipitation is approximately 152 inches (386 cm).</p><p>The Ketchikan area was covered by glacier ice at least once and probably several times during the Pleistocene Epoch. The present topography, characterized by elongate lakes, U-shaped valleys, fiords, inlets, and passages, clearly reflects the effects of glaciation. The presence of emergent marine deposits, at least 300 feet (91 m) above sea level, shows that the land has been uplifted relative to sea level since the last deglaciation of the region.</p><p>Bedrock is exposed or is near the surface throughout most of the mapped area. The bedrock consists chiefly of metamorphic rocks. In a few places these rocks have been intruded by igneous rocks. Exposed metamorphic rocks are mostly thinly foliated schists and phyllites, metamorphosed to greenschist facies. Foliation generally strikes northwest with moderate to steep dips to the northeast. Most of the rock is fairly competent and near-vertical cuts tend to be stable. The more indurated metamorphic rock can be used for riprap, but more durable blocks generally can be obtained from the igneous rock.</p><p style=\"text-align: left;\" data-mce-style=\"text-align: left;\">The surficial deposits have been divided into the following map units on the basis of their time of deposition, mode of origin, and grain size: (1) undifferentiated drift (Qd), (2) elevated marine deposits (Qm), (3) stream alluvium (Qa), (4) fan-delta deposits (Qf), and (5) modern beach deposits (Qb). Manmade fill (f) also is mapped as a separate unit. Muskeg, colluvium, and offshore deposits are not included as map units but are discussed in the report under the heading \"Surficial deposits (not shown on map).\" The undifferentiated drift deposits consist mostly of till or other diamictons, generally less than 25 feet (7.6 m) thick. Exposed elevated marine deposits (Qm) generally consist of sand and gravel less than 5 feet (1.5 m) thick. Stream alluvium (Qa) is chiefly sand, gravel, cobbles, and boulders probably everywhere less than 15 feet (4.6 m) thick. Fan-delta deposits (Qf) consist mostly of loose sand, gravel, and boulders as much as 50 feet (15 m) thick. Modern beach deposits (Qb) are mostly loose sand and gravel generally less than 10 feet (3 m) thick. Two basically different types of manmade fill are present: (1) large fills along the waterfront, commonly 5 to 15 feet (1.5-4.6 m) thick, consisting of silt, sand, gravel, rock, and diverse other materials, and (2) fills, generally less than 10 feet (3 m) thick and consisting of sand, gravel, or crushed rock, placed inland from the waterfront and used as pads for buildings and parking areas. Fairly thick deposits of muskeg may be present in the southeastern part of the mapped area but have not been examined in the field. Colluvial deposits, locally 5 to 8 feet (1.5-2.4 m) thick, consist mostly of decomposing bedrock fragments. Offshore deposits are poorly known; near-shore loose sand and gravel rest on a sloping bedrock surface.</p><p>Southeastern Alaska lies within the circum-Pacific seismic belt that rims the northern Pacific Basin and has been tectonically active since at least early Paleozoic time. Large-scale faulting has been common. The two most prominent fault systems in southeastern Alaska and surrounding regions are (1) the Denali fault system, and (2) the Fairweather-Queen Charlotte Islands fault system. Of the two, the Fairweather-Queen Charlotte Islands fault system is the more active and of most significance in relation to the Ketchikan area. Ketchikan lies within the northwest trend of the Gravina-Nutzotin belt of fault thrusting. The trends of at least some of the linear fiords near the mapped area are controlled by faults. However, it is not known whether a major fault extends up Tongass Narrows offshore from Ketchikan.</p><p>Between 1899 and 1970, five earthquakes having magnitudes of 8 or greater occurred in or near southeastern Alaska or in adjacent offshore areas; three have occurred having magnitudes of between 7 and 8, at least eight with magnitudes of between 6 and 7, 15 with magnitudes of between 5 and 6, and about 140 have been recorded with magnitudes of less than 5 or of unassigned magnitudes. All of the earthquakes with magnitudes greater than 8, and a large proportion of the others, appear to be related to the Fair-weather-Queen Charlotte Islands fault system or to the connecting Chugach-St. Elias fault to the northwest. Within a 50-mile (80-km) radius of Ketchikan, epicenters of three earthquakes with magnitudes of 5 or less have been recorded. Within a radius of 100 miles (160 km), 10 epicenters have been recorded, two with magnitudes between 6 and 7 and eight with magnitudes of 5 or less. Although no instrumentally recorded earthquakes had epicenters in the mapped area, at least 32 earthquakes that had epicenters elsewhere were felt or possibly felt in Ketchikan. Most of these earthquakes probably had epicenters along the Queen Charlotte Islands fault.</p><p>Ketchikan is tentatively assigned by me to seismic zone 2. This is a zone in which magnitudes of the largest expectable earthquake would range from 4.5 to 6.0 and where moderate damage could be expected. Large earthquakes of magnitude 8 or greater, however, can be expected to occur from time to time along the Queen Charlotte Islands fault. Ground motion from these earthquakes, although attenuated with distance, may still be sufficiently strong at Ketchikan to cause substantial damage.</p><p>Possible future earthquake effects include: (1) land-level changes caused by local faulting or by large-scale regional deformation, (2) ground shaking, (3) compaction, (4) liquefaction, (5) subaerial and submarine sliding, (6) water-sediment ejection and ground fracturing, (7) reaction of sensitive and quick clays, and (8) effects of tsunamis, seiches, and other abnormal water waves. Although land-level changes due to local faulting are unlikely, large-scale regional deformation may cause uplift or subsidence in Ketchikan. Adverse effects would be confined mainly to the waterfront area. This area also would be most heavily damaged if Ketchikan were strongly shaken by an earthquake. Nonengineered, loose, manmade fills and fan-delta deposits in this area probably would be subject to the strongest shaking. These deposits probably also are most subject to compaction, liquefaction, sliding, and water-sediment ejection. Earthquake effects expectably would be considerably fewer and less severe for the part of Ketchikan upslope from the harbor area because bedrock is at or near the surface in large parts of the area. No sensitive clays have been identified but, if present, they probably are confined to the till and other diamicton deposits in the northeastern part of the mapped area. Tsunami waves are not expected to have a local generation source. Those arriving from a distant source, although potentially highly destructive, probably would be greatly attenuated before arriving at Ketchikan. Seiche waves may develop on lakes near the mapped area and possibly cause failure of earth-fill dams. Destructive waves generated by earthquake-induced local submarine sliding appear to be unlikely in the Ketchikan area.</p><p>Geologic hazards in the area that are not caused by earthquakes are believed to be relatively minor. They include: (1) landsliding and subaqueous sliding, and (2) flooding. Only minor landsliding has occurred in the mapped area, but the potential for sliding may increase as the city expands and heavily timbered areas are cleared, with attendant accelerated erosion and mass wasting. The greatest potential for subaqueous sliding is along the shoreline, where fairly thick fan-delta deposits rest on a sloping bedrock surface. Periodic flooding has occurred on some creeks in the mapped area and can be expected to occur from time to time in the future.</p><p>In order that more accurate evaluations of geologic hazards can be made in the future, several recommendations are made for additional studies.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr75250","usgsCitation":"Lemke, R., 1975, Reconnaissance engineering geology of the Ketchikan area, Alaska, with emphasis on evaluation of earthquake and other geologic hazards: U.S. Geological Survey Open-File Report 75-250, Report: iii, 65 p.; 1 Plate: 53.36 x 18.70 inches, https://doi.org/10.3133/ofr75250.","productDescription":"Report: iii, 65 p.; 1 Plate: 53.36 x 18.70 inches","costCenters":[],"links":[{"id":419097,"rank":3,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1975/0250/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":419096,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1975/0250/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":148248,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1975/0250/report-thumb.jpg"}],"country":"United States","state":"Alaska","city":"Ketchikan","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -132.1008985363706,\n              55.53989430363504\n            ],\n            [\n              -132.1008985363706,\n              55.10963711958067\n            ],\n            [\n              -131.2097064951564,\n              55.10963711958067\n            ],\n            [\n              -131.2097064951564,\n              55.53989430363504\n            ],\n            [\n              -132.1008985363706,\n              55.53989430363504\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a74e4b07f02db64462b","contributors":{"authors":[{"text":"Lemke, Richard W.","contributorId":59409,"corporation":false,"usgs":true,"family":"Lemke","given":"Richard W.","affiliations":[],"preferred":false,"id":169808,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

These include garnet, chrome spinel, augite, pigeonite, diopside, hornblende, enstatite, hypersthene, epidote, clinozoisite, zoisite, apatite, tourmaline, chloritoid, sphene, zircon, and opaque minerals. Much rarer constituents are glaucophane, lamprobolite, rutile, kyanite, staurolite, and riebeckite.</p><p>The heavy-mineral fractions that were not treated with hydrochloric acid contain \"iron-stained aggregates\", grains of unidentifiable material encrusted with limonite. Samples containing relatively high percentages of iron-stained aggregates and altered opaque minerals occur in depths less than 10 m and within 16 km from shore.</p><p>Garnet increases in abundance from east to west, which corresponds to a similar increase in garnet abundance in coastal outcrops of the Gubik Formation sands. Only garnet and iron-stained aggregates appear to have source-related distribution patterns. The other heavy minerals lack distinct distributive provinces, reflecting an environment dominated by intense mixing by ice-gouging and bioturbation and a homogenous source area. Waves and currents are not strong enough to sort sediments at depths greater than 10 m except during summer storms.</p><p>The source of the Beaufort Sea heavy minerals is dominated by contributions from the Alaskan North Slope deposits of Tertiary and younger age. The Colville River, largest in the region, is probably the most influential in transporting sediments, but because of wave and current—mixing of sediments on the shelf, exact contributions from each river drainage cannot be ascertained. Coastal erosion of the Gubik Formation is probably at least as important as the Colville River in supplying heavy minerals to the Beaufort Sea.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr75667","usgsCitation":"Luepke, G., 1975, Heavy-mineral trends in the Beaufort Sea: U.S. Geological Survey Open-File Report 75-667, Report: 38 p.; 8 Plates: 35.57 x 23.70 inches or smaller, https://doi.org/10.3133/ofr75667.","productDescription":"Report: 38 p.; 8 Plates: 35.57 x 23.70 inches or smaller","costCenters":[],"links":[{"id":429124,"rank":10,"type":{"id":29,"text":"Figure"},"url":"https://pubs.usgs.gov/of/1975/0667/figure-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":429123,"rank":9,"type":{"id":29,"text":"Figure"},"url":"https://pubs.usgs.gov/of/1975/0667/figure-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":429122,"rank":8,"type":{"id":29,"text":"Figure"},"url":"https://pubs.usgs.gov/of/1975/0667/figure-4A.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":429121,"rank":7,"type":{"id":29,"text":"Figure"},"url":"https://pubs.usgs.gov/of/1975/0667/figure-4B.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":429120,"rank":6,"type":{"id":29,"text":"Figure"},"url":"https://pubs.usgs.gov/of/1975/0667/figure-5.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":429119,"rank":5,"type":{"id":29,"text":"Figure"},"url":"https://pubs.usgs.gov/of/1975/0667/figure-6-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":429118,"rank":4,"type":{"id":29,"text":"Figure"},"url":"https://pubs.usgs.gov/of/1975/0667/figure-6.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":429117,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1975/0667/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":429116,"rank":2,"type":{"id":27,"text":"Table"},"url":"https://pubs.usgs.gov/of/1975/0667/Table-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":148924,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1975/0667/report-thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Beaufort Sea","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -162.01067630655163,\n              71.33220429155887\n            ],\n            [\n              -162.01067630655163,\n              69.2681279384339\n            ],\n            [\n              -141.02032464064888,\n              69.2681279384339\n            ],\n            [\n              -141.02032464064888,\n              71.33220429155887\n            ],\n            [\n              -162.01067630655163,\n              71.33220429155887\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a61e4b07f02db635d3a","contributors":{"authors":[{"text":"Luepke, Gretchen","contributorId":91827,"corporation":false,"usgs":true,"family":"Luepke","given":"Gretchen","email":"","affiliations":[],"preferred":false,"id":169936,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

St. Matthew Island is made up of approximately 500 m of subaerial calc-alkaline volcanic rocks ranging in composition from high-alumina basalt to rhyolite. Four K-Ar analyses of samples from this volcanic sequence give Late Cretaceous ages of 65-77 m.y., and intercalated carbonaceous tuff layers yield Cretaceous pollen assemblages. Along the northeast coast of St. Matthew Island the volcanic rocks are intruded by granodiorite that gives an early Tertiary K-Ar age of 61 m.y.</p><p>Correlations with on-land geology in northeast Siberia and marine geophysical data from the western Bering Sea strongly suggest that St. Matthew Island represents a southeastward extension of the Okhotsk-Chukotsk belt, a Late Cretaceous and early Tertiary volcanic arc that borders the Pacific margin of Siberia for 3,000 km. The apparent continuation of this volcanic arc along the margin of the Bering shelf at least as far east as St. Matthew Island supports suggestions by Burk and by Scholl and others that in late Mesozoic time the Pacific plate margin coincided with the present-day Bering shelf margin and did not shift to the Aleutian trench until the end of Cretaceous or the beginning of Tertiary time.</p><p>During the summer of 1971 the U.S. Geological Survey conducted a reconnaissance expedition to St. Matthew Island in the central Bering Sea aboard the Survey research vessel Don J. Miller II. The purpose of the expedition was to obtain basic geologic information on the age and lithologic character of the volcanic rocks on St. Matthew as part of a broad program of onshore and offshore investigations of the energy and mineral resources of the Bering Sea shelf. St. Matthew Island had not been mapped previously and available geologic information was confined to brief notes from early exploratory surveys of the Bering Sea region published more than 50 years ago (Dawson, 1894; Emerson, 1910).</p><p>St. Matthew Island together with two small neighboring islands, Hall and Pinnacle, is situated 400 km west of mainland Alaska on the broad continental shelf that connects Alaska and Siberia (fig. 1). Although these islands have a combined area of only 350<sup>2</sup> km, they are important because they provide a rare subaerial exposure of the geology of the shelf and furnish new information on the tectonic history of the Bering Sea region.</p><p>This report briefly describes the geology of the island and suggests how the island fits into the tectonic framework of the Bering Sea region.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr75150","usgsCitation":"Patton, W.W., Lanphere, M.A., Miller, T.P., and Scott, R., 1975, Age and tectonic significance of volcanic rocks on St. Matthew Island, Bering Sea, Alaska: U.S. Geological Survey Open-File Report 75-150, 18 p., https://doi.org/10.3133/ofr75150.","productDescription":"18 p.","costCenters":[],"links":[{"id":423344,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1975/0150/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":144105,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1975/0150/report-thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Bering Sea, St. Matthew Island","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -173.19656898891907,\n              60.72952223911312\n            ],\n            [\n              -173.19656898891907,\n              60.248433293048976\n            ],\n            [\n              -172.1421533581664,\n              60.248433293048976\n            ],\n            [\n              -172.1421533581664,\n              60.72952223911312\n            ],\n            [\n              -173.19656898891907,\n              60.72952223911312\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae3e4b07f02db6896f3","contributors":{"authors":[{"text":"Patton, William Wallace Jr.","contributorId":72346,"corporation":false,"usgs":true,"family":"Patton","given":"William","suffix":"Jr.","email":"","middleInitial":"Wallace","affiliations":[],"preferred":false,"id":158681,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lanphere, Marvin A. alder@usgs.gov","contributorId":2696,"corporation":false,"usgs":true,"family":"Lanphere","given":"Marvin","email":"alder@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":158678,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Miller, Thomas P. tmiller@usgs.gov","contributorId":4183,"corporation":false,"usgs":true,"family":"Miller","given":"Thomas","email":"tmiller@usgs.gov","middleInitial":"P.","affiliations":[{"id":121,"text":"Alaska Volcano Observatory","active":false,"usgs":true}],"preferred":false,"id":158679,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Scott, Richard A.","contributorId":14414,"corporation":false,"usgs":true,"family":"Scott","given":"Richard A.","affiliations":[],"preferred":false,"id":158680,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The 22 deep test wells that have been drilled since 1954 have been unsuccessful because structure is complex and because suitable reservoir rocks have not been found in favorable structural positions. Although it is possible that the factors controlling accumulation of petroleum may improve offshore, regional stratigraphic and structural considerations together with the limited geophysical data suggest that this is not necessarily the case.

Within the Yakutat region are some of the tallest mountains, some of the heaviest snowfalls, and the largest glacier in North America. Between the abrupt mountain front and the Gulf of Alaska lies a very gently sloping plain of outwash derived from repeated cycles of advance followed by melt and retreat of glaciers during the Quaternary Period. The latest melting probably took place 500 to 600 years ago. Yakutat is built upon the moderately steep moraine that is the product of melting of one of these glaciers. Near Yakutat, surficial deposits are as much as 700 feet thick and probably overlie siltstone, sandstone, and mudstone. The eight general categories of mapped surficial deposits include artificial fill, organic, eolian, beach, delta-estuarine, alluvial, and outwash deposits, and deposits of the outer Yakutat Bay moraine complex.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr75529","usgsCitation":"Yehle, L.A., 1975, Preliminary report on the reconnaissance engineering geology of the Yakutat area, Alaska, with emphasis on evaluation of earthquake and other geologic hazards: U.S. Geological Survey Open-File Report 75-529, Report: iv, 136 p.; 2 Plates: 17.55 x 23.84 inches and 23.76 x 22.10 inches, https://doi.org/10.3133/ofr75529.","productDescription":"Report: iv, 136 p.; 2 Plates: 17.55 x 23.84 inches and 23.76 x 22.10 inches","costCenters":[],"links":[{"id":419431,"rank":4,"type":{"id":29,"text":"Figure"},"url":"https://pubs.usgs.gov/of/1975/0529/figure-2.pdf","text":"Figure 2","linkFileType":{"id":1,"text":"pdf"}},{"id":419430,"rank":3,"type":{"id":29,"text":"Figure"},"url":"https://pubs.usgs.gov/of/1975/0529/figure-4.pdf","text":"Figure 4","linkFileType":{"id":1,"text":"pdf"}},{"id":419427,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1975/0529/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":150377,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1975/0529/report-thumb.jpg"}],"scale":"63360","country":"United States","state":"Alaska","otherGeospatial":"Yakutat area","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -140.46791499075454,\n              59.89062741426659\n            ],\n            [\n              -140.46791499075454,\n              59.494396417496176\n            ],\n            [\n              -139.5015327447604,\n              59.494396417496176\n            ],\n            [\n              -139.5015327447604,\n              59.89062741426659\n            ],\n            [\n              -140.46791499075454,\n              59.89062741426659\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aaee4b07f02db66c788","contributors":{"authors":[{"text":"Yehle, Lynn A. yehle@usgs.gov","contributorId":3794,"corporation":false,"usgs":true,"family":"Yehle","given":"Lynn","email":"yehle@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":173258,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
