Caltech studies reveal microquake swarms before earthquakes

Hiroo Kanamori and other seismologists from the California Institute of Technology reported at the 1977 AGU Fall Meeting the first evidence of anomalous clusters of small earthquakes preceding the San Fernando earthquake of 1971. Their discovery of such clusters in earthquake records from central and southern California offers considerable encouragement that these swarms may be used to predict larger earthquakes.
