Expectable Earthquakes and their ground motions in the Van Norman Reservoirs Area
R. L. Wesson, R.A. Page, D.M. Boore, R. F. Yerkes
1974, Circular 691-B
The upper and lower Van Norman dams, in northwesternmost San Fernando Valley about 20 mi (32 km) northwest of downtown Los Angeles, were severely damaged during the 1971 San Fernando earthquake. An investigation of the geologic-seismologic setting of the Van Norman area indicates that an earthquake of at least M...

Garland Bayard Gott, Joseph Moses Botbol
1974, Open-File Report 74-67
The ore deposits in the northern part of the Coeur d'Alene district are located within rocks of the Belt Supergroup that have been intruded by Cretaceous quartz monzonites. Lead-zinc-silver replacement veins constitute most of the deposits. The geometry of the district has been modified by post-ore faulting along the Osburn,...

Digital modeling of radioactive and chemical waste transport in the Snake River plain aquifer at the National Reactor Testing Station, Idaho
J.B. Robertson
1974, Open-File Report 74-1089
Industrial and low-level radioactive liquid wastes at the National Reactor Testing Station (NRTS) in Idaho have been disposed to the Snake River Plain aquifer since 1952. Monitoring studies have indicated that tritium and chloride have dispersed over a 15-square mile (39-square kilometer) area of the aquifer in low but detectable...

1974, Open-File Report 74-57
The Eagle River — Chugiak area is a rapidly growing residential part of the Greater Anchorage Area Borough, south-central Alaska. High-density, urban development in some parts of the area may be restricted because of the nature of the surficial geologic materials and their hydrologic characteristics. This report assembles all information...
