<p>In this paper is performed a systematic survey of triggered tremor along the San Andreas Fault incentral California for the 31 teleseismic earthquakes with Mw 7.5 since 2001.</p>

<p>Since its initial discovery nearly a decade ago, non-volcanic tremor has provided information about a region of the Earth that was previously thought incapable of generating seismic radiation. A thorough explanation of the geologic process responsible for ...

Seismic velocity changes and nonvolcanic tremor activity in the Parkfield area in California reveal that large earthquakes induce long-term perturbations of crustal properties in the San Andreas fault zone.
