Postseismic response of repeating aftershocks
Web20 Feb 2004 · About 10% of seismic events in and near China from 1985 to 2000 were repeating events not more than about 1 kilometer from each other. We cross-correlated seismograms from ∼14,000 earthquakes and explosions and measured relative arrival times to ∼0.01 second, enabling lateral location precision of about 100 to 300 meters. WebPostseismic variations in seismic moment and recurrence interval of repeating earthquakes ... We analyze a subset of 34 M-0.4-2.1 repeating earthquake sequences (RES) from 1987 to 2009 at Parkfield to examine the variation of their recurrence properties in space and time. Following a 2004 M6 earthquake, many of the repeating events have greatly ...
