Tectonomagnetic effects
M. Johnston
1978, Earthquake Information Bulletin (USGS) (10) 82-87
Measurements of the actual stress within the Earth and its changes with time are very difficult. It is much easier to monitor the direct effects of this stress, such as ground strain, or the indirect effects, such as changes in resistivity, strain, changes in seismic velocity or changes in magnetic...
Earthquakes, March-April 1978
W. J. Person
1978, Earthquake Information Bulletin (USGS) (10) 192-194
Earthquakes caused fatalities in Mexico and Sicily; injuries and damage were sustained in eastern Kazakh SSR and Yugoslavia. There were four major earthquakes; one south of Honshu, Japan, two in the Kuril Islands region, and one in the Soviet Union. The United States experienced a number of earthquakes, but only...
Earthquakes; November-December, 1978
W. J. Person
1978, Earthquake Information Bulletin (USGS) (11) 110-112
Seismically speaking, the last 2 months were the most active of the year. There were six major earthuakes having magnitudes (M) ranging from 7.0 to 7.9 throughout the world: the Solomon Islands, Mexico (the largest of the year, M=7.9), the Kuril Islands, Taiwan, the Philippine Islands, and western Iran. THe...
Earthquakes, November-December 1977
W. J. Person
1978, Earthquake Information Bulletin (USGS) (10) 97-99
Two major earthquakes occurred in the last 2 months of the year. A magnitude 7.0 earthquake struck San Juan Province, Argentina, on November 23, causing fatalities and damage. The second major earthquake was a magnitude 7.0 in the Bonin Islands region, an unpopulated area. On December 19, Iran experienced a...
Tiltmeter studies in earthquake prediction
M. Johnston
1978, Earthquake Information Bulletin (USGS) (10) 182-186
Our knowledge is still very limited as to the way in which the Earth's surface deforms around active faults and why it does so. By far the easiest method of providing clues to the mechanisms involved is to record the associated pattern of tilt of the Earth's surface. tilt measurements give...
Earthquakes; July-August 1977
W. J. Person
1978, Earthquake Information Bulletin (USGS) (10) 26-27
July and August were somewhat active seismically speaking, compared to previous months of this year. There were seven earthquakes having magnitudes of 6.5 or greater. The largest was a magnitudes of 6.5 or greater. The largest was a magnitude 8.0 earthquake south of Sumbawa Island on August 19 that killed...
Earthquakes; January-February, 1978
W. J. Person
1978, Earthquake Information Bulletin (USGS) (10) 148-149
Seismically speaking, 1978 began slowly. The first major earthquake (magnitude 7.0 and above) of the year occurred on February 9 and was centered in the Kermadec Islands region in the South Pacific Ocean. The first destructive earthquake of the year strukc southern Honshu, Japan, on January 14. The magnitude 6.5...
Paleomagnetic evidence for a Late Cretaceous deformation of the Great Valley Sequence, Sacramento Valley, California
Edward A. Mankinen
1978, Journal of Research of the U.S. Geological Survey (6) 383-390
Paleomagnetic samples from five localities within the Great Valley sequence range in age from Late Jurassic to Late Cretaceous. All samples possess normal polarity, and alternating-field demagnetization experiments show that the remanence was acquired after the sequence was folded. A mean paleomagnetic pole position determined from 17 demagnetized samples is...
Continuous strain measurements near the San Andreas Fault
M. Johnston
1978, Earthquake Information Bulletin (USGS) (10) 187-191
Changes in the state of stress in the Earth's crust produces corresponding changes in the state of strain and may result, as a consequence, in damaging earthquakes. Monitoring ground strain can, therefore, help us in understanding how stress changes occur and when they are likely to lead to this kind...
Quality of water in Pascagoula and Escatawpa Rivers, Jackson County, Mississippi
Gene A. Bednar
1978, Open-File Report 78-913
The chemical and physical properties and the range of concentrations of most constituents in water in the Pascagoula and Escatawpa Rivers during the period May 17-19, 1977, varied rapidly between high and low tides, primarily as the result of interactions of freshwater inflow with highly mineralized Gulf waters. The water...

Studies on vertical and horizontal transmission of duck plague virus in apparently healthy waterfowl
Elizabeth C. Burgess
1978, Thesis
Healthy waterfowl were found to be carriers of duck plague (DP) virus. Black ducks (Anas rubripes) and Canada geese (Branta canadensis) surviving a natural outbreak of DP at Coloma, Wisconsin, in 1973 yielded DP virus in cloacal swabs taken four years postinfection. Experimental infection of previously unexposed mallard ducks (Anas...

Biology of larval and metamorphosing sea lampreys, Petromyzon marinus, of the 1960 year class in the Big Garlic River, Michigan, Part II, 1966-72
Patrick J. Manion, Bernard R. Smith
1978, Technical Report 30
The 1960 year class of sea lampreys, Petromyzon marinus, isolated in a tributary of southern Lake Superior continued to yield information on the early life history of the sea lamprey. The larval population persisted and newly metamorphosed individuals were captured from 1966 until the study was terminated in 1972. The...

Mössbauer spectroscopic investigation of iron species in coal
Gerard V. Smith, Juei-Ho Liu, Mykola Saporoschenko
1978, Fuel (57) 41-45
A series of Herrin No. 6 coal and three coal-derived samples have been examined by Mo??ssbauer spectroscopy. It is established that Mo??ssbauer spectroscopy can be used to identify multiple iron species in a whole coal or an autoclaved char sample without the need to concentrate the minerals to enhance resolution....
Earthquake swarms and local crustal spreading along major strike-slip faults in California
C.S. Weaver, D.P. Hill
1978, Pure and Applied Geophysics PAGEOPH (117) 51-64
Earthquake swarms in California are often localized to areas within dextral offsets in the linear trend in active fault strands, suggesting a relation between earthquake swarms and local crustal spreading. Local crustal spereading is required by the geometry of dextral offsets when, as in the San Andreas system, faults have...

Range charts and no-space graphs
Lucy E. Edwards

No-space graphs present one solution to the familiar problem: given data on the occurrence of fossil taxa in separate, well-sampled sections, determine a range chart; that is, a reasonable working hypothesis of the total range in the area in question of each taxon studied. The solution presented here treats only...

Marvin G. Sherrill
1978, Water Supply Paper 2047
Door County is in northeastern Wisconsin and is an area of 491 square miles. The county forms the main body of the peninsula between Green Bay and Lake Michigan. The land surface is an upland ridge controlled by the underlying bedrock. The west edge of the ridge forms an escarpment...
