Lessons from (triggered) tremor
Joan Gomberg
2010, Journal of Geophysical Research B: Solid Earth (115)
I test a “clock-advance” model that implies triggered tremor is ambient tremor that occurs at a sped-up rate as a result of loading from passing seismic waves. This proposed model predicts that triggering probability is proportional to the product of the ambient tremor rate and a function describing the efficacy...
