Strong-Motion Earthquake Accelerograms Digitized and Plotted Data. Volume II. Corrected Accelerograms and Integrated Ground Velocity and Displacement Curves. Part T. Accelerograms IIT274Through IIT293,

摘要

The first set of twenty corrected earthquake accelerograms was published in September 1971,as Volume II,Part A,Report No. EERL 71-50,the first report of the Volume II series. That issue also contained introductory material and background information describing the types of corrections used. The corresponding uncorrected data appeared earlier in Volume I,Part A,Report No. EERL 70-20. Both of these reports,containing references related to the records themselves and the various procedures,should be referred to by all users of the data. This issue,Volume II,Part T,Report No. EERL 75-50,contains records from the El Centro,California,site in the basement of the Imperial Valley Irrigation District District substation,from 1938to 1966including nine groups of aftershocks of the May 18, 1940,Imperial Valley earthquake.
