Special Event Detection for an Unattended Seismic Observatory
Abstract
A practical event detection system for monitoring remote three-axis seismometers is described. The self-contained system, through use of digital storage, records data from 30 seconds before an event is triggered until earth motion subsides. Intended for use in an unmanned seismic observatory, the device is capable of detecting near events as well as the multiple phases of teleseisms. Provision has been made for the on-site adjustment of critical detection parameters. A prototype has been tested on prerecorded data at the Vela Seismological Center in Alexandria, Virginia. A summary and interpretation of the test results is included.
