Seismic Event Compressed Scale High Frequency Quakes

NSSDCA ID: PSPG-00496

Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1972-09-17 to 1975-01-13

Description

This data set consists of a magnetic tape of distant seismic events, believed to be moonquakes, observed with large amplitudes on the short-period components of the PSE. These are called high-frequency teleseismic (HFT) events. Each frame of data on the tape consists of eighteen 36-bit words. The first three words contain timing, synchronization, and error information. The remaining words contain the recorded seismic data. Each seismic data segment contains 10 bits, or a range from 0 to 1023 digital units (DU). Sensor equilibrium data values are near 500 digital units. The tape was written in binary on a PDP-15 computer.
