Earthquake watch to be discussed



The most intensive earthquake monitoring program ever mounted in this country is going on near Parkfield, Calif., about midway between Los Angeles and San Francisco on the San Andreas fault. Although no particularly large or destructive quake is feared in Parkfield, the regularity with which earthquakes have occurred there in the past makes the site unique. Since the next quake has been forecast for 1988 (±5 years), seismologists have decided to blanket the area with data-gathering equipment in hopes of having front-row seats for the expected seismic show. The studies in Parkfield will be the topic of an all-day session sponsored by the Seismology Section on Friday, December 13, at the AGU Fall Meeting in San Francisco, Calif.
