Identification of Earthquakes and Underground Explosions

Abstract

During the period January 1970 through August 1970 long period seismographs were operated at the Grand Saline Salt Mine in North-Central Texas. This report concentrates on the following tasks as outlined in the original statement of work: Obtain digital data, in a standard format, of long period signals and noise; investigate methods of filtering which can be used to improve signal to noise ratios; and study regional variations in frequency dependent absorption of long period surface waves.
