Self-similar earthquake triggering, Båth’s law, and foreshock/aftershock magnitudes: Simulations, theory, and results for southern California
[1] Båth’s law, the observation that the largest aftershock is, on average, 1.2 magnitudes smaller than its main shock, independent of main shock size, suggests some degree of self-similarity in earthquake triggering. This behavior can largely be explained with triggering models in which the increased triggering caused by larger magnitude events is exactly compensated for by their decreased num...
متن کاملWidespread triggering of nonvolcanic tremor in California.
We identified seven locations on or near the transform plate boundary in California where nonvolcanic tremor was triggered by the 2002 Denali earthquake. This result implies that the conditions essential for nonvolcanic tremor exist in a range of tectonic environments. Models explaining tremor typically require conditions endemic to subduction zones, that is, high temperatures and fluid pressur...
متن کاملThe Foreshock Activity of the 1971 San Fernando Earthquake, California by Mizuho Ishida and Hiroo Kanamori
All of the earthquakes which occurred in the epicentral area of the 1971 San Fernando earthquake during the period from 1960 to 1970 were relocated by using the master-event method. Five events from 1969 to 1970 are located within a small area around the main shock epicenter. This cluster of activity is clearly separated spatially from the activity in the surrounding area, so these five events ...

متن کاملRepeated foreshock sequences in the thrust faulting environment of eastern Taiwan
[1] Foreshock sequences have repeatedly been observed in the thrust faulting system of the Chengkung area in eastern Taiwan. Examinations of earthquakes since 1992 in this area show all six of the larger earthquakes (ML R 5) had foreshocks at a distance of only a few kilometres within just a few days before the main shocks. The largest earthquake (ML = 6.5) on December 10, 2003 was preceded by ...
