Studies of High-Frequency Seismic Wave Propagation.

Abstract

This final report results are: (1) A study of the location of regional seismic events using a sparse network, with an application to eastern Kazakhstan. (2) An analysis of high frequency seismic observations collected in eastern Kazakhstan, including in particular calibration chemical explosions. (3) A study of the discrimination of quarry blasts from single explosions, using sonogram analysis of data collected in eastern Kazakhstan. (4) The extension of the discrimination methodology developed in the previous paper to small aperture array data, and application to the automated discrimination between earthquake and quarry blasts at NORESS. (5) The use of a new technique, labelled beam stack imaging, to map shallow crust scatterers near a small aperture array, with applications to NORESS. (6) A study of the polarization characteristics of high- frequency borehole seismograms recorded near Anza, California. (7) An analysis of attenuation and site effects on high-frequency seismic waves, using high- frequency borehole seismograms recorded in the San Jacinto fault zone, near Anza, California.
