Installation, Maintenance, Operation, and Development Support for a Prototype Seismic Data Center. Phase 2
Abstract
This report summarizes the activities at the Center for Seismic Studies for phase II of a three-phase contract. Real-time data from the Regional Seismic Test Network (RSTN) were routinely recorded during the first quarter of the period. Data from the Global Digital Seismic Network (GDSN) and the Seismic Research Observatories (SRO) were formatted and archived along with data from several other sources. Databases were developed using the commercial INGRES relational database system to provide users access to event, arrival, and waveform data. Several improvements to the Center's computer systems were made. The computers were connected to a local area network allowing each user access to any of the computers rather than to just the one where the user's terminal is connected. A 9.6 KB phone line to Reston, VA, was installed for S-CUBED, another DARPA contractor. A long-period seismograph was installed in the lobby so that visitors could observe seismic data being recorded. An additional VAX computer was acquired. Finally, several problems with the satellite communication systems were encountered and corrected. Programs to support the collection and processing of the seismic data were improved and enhanced. A control system for the Center software was implemented so that formal procedures to maintain the software could be imposed.
