Seismic refraction study of crustal structure in the western United States Seismic refraction study of crustal structure in the western United States
A network of 64 seismic-refraction profiles recorded by the U.S. Geological Survey in California and Nevada and adjacent areas of Idaho, Wyoming, Utah, and Arizona from 1961 to 1963 was re-interpreted. From record sections compiled for all profiles, a basic travel-time diagram can be derived. In addition to the first arrivals on profiles in the Snake River Plain, the northern Basin and...

Interstitial water studies on small core samples, Deep Sea Drilling Project, Leg 3 Interstitial water studies on small core samples, Deep Sea Drilling Project, Leg 3
Eleven samples of fluids which had been squeezed on board ship, and four, packaged sediment samples were received in our laboratories. As in Leg 2, the volumes of fluid available were scanty and did not permit multiple determinations of constituents in many of the samples; in Hole 21 the fluid available sufficed only for refractometer readings (a few tenths of a milliliter). Therefore...

Effects of local geology on ground motion near San Francisco Bay Effects of local geology on ground motion near San Francisco Bay
Measurements of ground motion generated by nuclear explosions in Nevada were made for 37 locations near San Francisco Bay, California. The results were compared with the San Francisco 1906 earthquake intensities and the strong-motion recordings of the San Francisco earthquake of March 22, 1957. The recordings show marked amplitude variations which are related consistently to the geologic...

Atmospheric collection of debris from the Revelstoke and Allende fireballs Atmospheric collection of debris from the Revelstoke and Allende fireballs
In two separate events, Revelstoke and Allende, the air through which a fireball had been observed to pass was sampled for meteoritic debris. Particulate matter was collected on fibrous filters, which were mounted on aircraft and flown downwind from the site of the meteorite fall at altitudes of 10,000–12,000 m. From Revelstoke, a highly distinctive assemblage of particles was collected...

Interstitial water studies on small core samples, Deep Sea Drilling Project, Leg 5 Interstitial water studies on small core samples, Deep Sea Drilling Project, Leg 5
Leg 5 samples fall into two categories with respect to interstitial water composition: 1) rapidly deposited terrigenous or appreciably terrigenous deposits, such as in Hole 35 (western Escanaba trough, off Cape Mendocino, California); and, 2) slowly deposited pelagic clays and biogenic muds and oozes. Interstitial waters in the former show modest to slight variations in chloride and...

Effects of the earthquake of March 27, 1964, on the Alaska Railroad Effects of the earthquake of March 27, 1964, on the Alaska Railroad
In the 1964 Alaska earthquake, the federally owned Alaska Railroad sustained damage of more than $35 million: 54 percent of the cost for port facilities; 25 percent, roadbed and track; 9 percent, buildings and utilities; 7 percent, bridges and culverts; and 5 percent, landslide removal. Principal causes of damage were: (1) landslides, landslide-generated waves, and seismic sea waves that...

The Alaska earthquake, March 27, 1964: Lessons and conclusions The Alaska earthquake, March 27, 1964: Lessons and conclusions
One of the greatest earthquakes of all time struck south-central Alaska on March 27, 1964. Strong motion lasted longer than for most recorded earthquakes, and more land surface was dislocated, vertically and horizontally, than by any known previous temblor. Never before were so many effects on earth processes and on the works of man available for study by scientists and engineers over so...
