Improved Procedures for Determining Seismic Source Depths from Depth Phase Information.

摘要

To compensate for sparse coverage of the AI events by the SRO/ASRO and SDCS networks, the depth determination program has been modified to process seismic array data. This will substantially increase the proportion of AI events that can be processed. A total of 28 events were examined during this quarter; 14 of these could not be processed due to inadequate data. Of the remaining 14 events, depth estimates were obtained on 6 of them, 4 were found to be outside the 10-80 km depth range examined, and 4 are in secondary processing. (Author)
