Abstract:

A practical three-channel seismic-event-discriminator breadboard was employed at the Harvard College Observatory located in Harvard, Mass. to monitor, in real time, three short-period seismometers. The major objective for placing this breadboard system in the field was to demonstrate that preprocessing of seismic data on-site thereby reducing recording and transmitting requirements was a viable and workable concept. Background information pertaining to the event-discriminator test plan experimental test installation including the seismometer set up, interfaces and recording equipment interface circuits, and calibration procedures and test results of the seismometers is provided. A summary and interpretation of in-field testing data is presented.
