The State - News from April 5, 1989
The quake that shook the San Francisco Bay area Monday was predicted by U.S. Geological Survey scientists, said a USGS seismologist in Menlo Park. “We knew there would be an earthquake here,” said Al Lindh. “Honest we did.” He said he and his colleagues foresaw that a mile-long stretch of the Calaveras Fault was due for a 9.5-kilometer-deep quake with a magnitude of just over 5, because stress was building. The quake was slightly weaker than they expected. The USGS measured it at 5.0, while University of California seismologists read it at 4.4. No major damage resulted and no injuries were reported.
