Abstract:

The effort required to operate and maintain the Seismic Data Analysis Center during the fiscal year of 1981 is described in this report. Statistics concerning the operational effectiveness and the utilization of the systems at the Center are also given. The major activities associated with maintaining the operating systems, providing data services, and performing maintenance are discussed. The development effort and improvements made to the stystems supporting the geophysical research include capabilites added to the Regional Event Location System and the Automation Association program. Other tasks reported include the result of implementing a front end processor called an intelligent line interface to do real-time signal detection, the effects of altering the configuration of the detection systems, and the status of software developed to do interactive discrimination. A computer study was performed to determine a preferred system to accomplish the on-line data recording and support the data services activity.
