Surface displacement on the Imperial and Superstition Hills faults triggered by the Westmorland, California, earthquake of 26 April 1981
R. V. Sharp, J. J. Lienkaemper, M. J. Rymer
1982, Open-File Report 82-282
Parts of the Imperial and the Superstition Hills faults moved right-laterally at the ground surface at the time of or shortly following the ML 5.6 Westmorland earthquake of 26 April 1981. The displacements occurred prior to any significant aftershocks on either fault and thus are classed as sympathetic. Although the...
Water-quality assessment of the American River, California
M.V. Shulters
1982, Open-File Report 82-763
Based on an analysis of water-quality data from more than 168 sites, the American River was found to be of overall good quality and suitable for all beneficial uses specified by the State of California, even though its natural condition has been altered by man 's activities in the basin....
Hydrogeologic data from two wells at Myakka Head, Manatee County, Florida
