Abstract:

To compensate for sparse coverage of the AI events by the SROASRO 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.
