Gravity survey and regional geology of the Prince William Sound epicentral region, Alaska
J. E. Case, D.F. Barnes, George Plafker, S. L. Robbins
1966, Professional Paper 543-C
Sedimentary and volcanic rocks of Mesozoic and early Tertiary age form a roughly arcuate pattern in and around Prince William Sound, the epicentral region of the Alaska earthquake of 1964. These rocks include the Valdez Group, a predominantly slate and graywacke sequence of Jurassic and Cretaceous age, and the Orca...
Slide-induced waves, seiching and ground fracturing caused by the earthquake of March 27, 1964 at Kenai Lake, Alaska
David S. McCulloch
1966, Professional Paper 543-A
The March 27, 1964, earthquake dislodged slides from nine deltas in Kenai Lake, south-central Alaska. Sliding removed protruding parts of deltas-often the youngest parts-and steepened delta fronts, increasing the chances of further sliding. Fathograms show that debris from large slides spread widely over the lake floor, some reaching the toe...
Magnetic data on the structure of the central Arctic Region
E. R. King, I. Zietz, L.R. Alldredge
1966, Geological Society of America Bulletin (77) 619-646
A study of 23,000 miles of total intensity aeromagnetic profiles in the central Arctic has been made by the U. S. Geological Survey and the U. S. Coast and Geodetic Survey. The profiles were flown at 20,000 feet above sea level and cover approximately 1,350,000 square miles of the Arctic Ocean between the North Pole...
Exposure of basement rock on the continental slope of the Bering Sea
D.W. Scholl, E. C. Buffington, D.M. Hopkins
1966, Science (153) 992-994
Profiles of repetitive seismic reflections reveal that the Bering continental slope, outer shelf, and rise overlay an acoustically reflective "basement" which extends at least 750 kilometers parallel to the trend of the slope. This acoustic basement is usually covered by several hundred meters of stratified sediments at the top and...
Evidence for an early recent warm interval in northwestern Alaska
David S. McCulloch, David M. Hopkins
1966, Geological Society of America Bulletin (77) 1089-1108
A warm interval that began at least 10,000 years ago and lasted until at least 8300 years ago is recorded in the coastal tundra covered area of northwestern Alaska by the presence of fossil wood of tree size or tree species, fossil beaver-gnawed wood found beyond the modern range of beaver, evidence of ice-wedge melting, buried soils, and soils that...
The Alaska earthquake, March 27, 1964: regional effects
David S. McCulloch, Samuel J. Tuthill, Wilson M. Laird, J. E. Case, D.F. Barnes, George Plafker, S. L. Robbins, Reuben Kachadoorian, Oscar J. Ferrians Jr., Helen L. Foster, Thor N. V. Karlstrom, M. J. Kirkby, Anne V. Kirkby, Kirk W. Stanley
1966, Professional Paper 543
This is the third in a series of six reports that the U.S. Geological Survey published on the results of a comprehensive geologic study that began, as a reconnaissance survey, within 24 hours after the March 27, 1964, Magnitude 9.2 Great Alaska Earthquake and extended, as detailed investigations, through several...
Effects of the earthquake of March 27, 1964, at Whittier, Alaska
Reuben Kachadoorian
1965, Professional Paper 542-B
Whittier, Alaska, lying at the western end of Passage Canal, is an ocean terminal of The Alaska Railroad. The earthquake that shook south-central Alaska at 5:36 p.m. (Alaska Standard Time) on March 27, 1964, took the lives of 13 persons and caused more than $5 million worth of damage to...
Effects of the earthquake of March 27, 1964, at Anchorage, Alaska
Wallace R. Hansen
1965, Professional Paper 542-A
Anchorage, Alaska’s largest city, is about 80 miles west-northwest of the epicenter of the March 27 earthquake. Because of its size, Anchorage bore the brunt of property damage from the quake; it sustained greater losses than all the rest of Alaska combined. Damage was caused by direct seismic vibration, by...
Water resources appraisal of the Anchorage area, Alaska
David A. Sommers, Melvin V. Marcher
1965, Open-File Report 65-151
At the present, water use in the Anchorage area amounts to about 21 mgd (million gallons per day); of this amount ground water accounts for about 10 mgd. By 1980, 60 mgd may be required to meet the demand.The greatest potential problem is overpumping the ground-water reservoir resulting in excessive...
Geology of the Romanzof Mountains, Brooks Range, northeastern Alaska
Edward G. Sable
1965, Open-File Report 65-141
This remote 700 square mile area in the Brooks Range is topographically rugged and geologically diverse; it contains a granitic pluton, low-grade metamorphic rocks, sedimentary rocks, and mafic igneous rocks, as well as glacial features.Rocks of sedimentary origin include from oldest to youngest:1.Neruokpuk Formation Middle and Upper Devonian(?), more than...
