LASA anomalies and their relations to crust and upper-mantle structure
H. M. Iyer, A.R. Jackson, J. H. Healy, T.E. Landers
1970, Open-File Report 70-170
Body-wave data from nine teleseisms recorded at the Large Aperture Seismic Array (LASA), Montana, have been analyzed. The events were at different azimuths and distances from LASA. Apparent-velocity measurements using arrival-time data at the subarrays differed by about 30 percent for events in the northwest and southeast directions.Apparent velocities were...
Chromite deposits of the north-central Zambales Range, Luzon, Philippines
Darwin L. Rossman
1970, Open-File Report 70-281
Peridotite and gabbro form an intrusive complex which is exposed over an area about 35 km wide and 150 km long in the center of the Zambales Range of western Luzon. The Zambales Complex is remarkable for its total known resources, mined and still remaining, of about 15 million metric...
Satellite relay telemetry of seismic data in earthquake prediction and control, 1968 and 1969
W. H. Jackson, Jerry P. Eaton
1970, Open-File Report 70-173
This report describes the progress of the Satellite Telemetry Earthquake Monitoring Program during the period 1 July 1968 through 30 June 1969. This research was supported by the National Aeronautics and Space Administration under Contract No. R-09-020-011, Task No. 160-75-01-50-10.The project was initiated in FY 1968 to evaluate the applicability...
Tectonic map of Indonesia: A progress report
Warren Bell Hamilton
1970, Open-File Report 70-150
Orogeny, volcanism, and seismicity are now intensely active in Indonesia. Many Dutch tectonists--Brouwer, Umbgrove, van Bemifielen, Smit4Sibinga, Vening Meinesz, Westerveld, and others--recognized that this complex cluster of islands represents an early stage in the evolution of orogenic belts. Not until Indonesia is understood can we comprehend the Alps. This report...
The Alaska earthquake, March 27, 1964: Lessons and conclusions
Edwin B. Eckel
1970, Professional Paper 546
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...
Water-surface elevations and channel characteristics for selected reaches of the Rogue River and Elk Creek, Jackson and Josephine Counties, Oregon
D.D. Harris
1970, Open-File Report 70-152
The central Rogue River valley, because of its mild climate, fertile soil, scenic attractions, and sport-fishery resource, has great potential for future population growth and industrial development. As the population grows and the area develops, zoning becomes necessary to assure the most beneficial use of the land, especially of the...
Summary of ground-water hydrological data in Michigan in 1969
P.R. Giroux, G.C. Huffman
1970, Open-File Report 70-136
The purpose of this report is to make available the records of ground-water levels in the principal aquifers of the State through 1969 and to compile other related data, such as records of groundwater pumpage, data on municipal, public and industrial water-supply facilities, and the effects of precipitation on ground-water...
