Earthquake statistics and prediction

Most aftershocks are too small to cause damage, but following a large mainshock one or more may be powerful enough to cause additional damage and casualties as well as also threaten the lives of rescuers searching for the injured.

Only about 25 aftershocks were recorded that occurred at a depth 35-40 km in the lower crust (Fig. 6b).A composite fault-plane solution of the aftershocks also reveals the reverse faulting with left lateral strike-slip motion.

earthquake aftershocks occurred above a rock body, with low electrical resistivity (.10 V·m), that is at depths below ;10 km. Aftershocks of the Denali fault earthquake have

Record-breaking earthquake intervals in a global catalogue ...

We also consider the aftershocks of the 2004 Parkfield earthquake and show that the record-breaking intervals are characterisedby very different statistics.

Does Aftershock Duration Scale With Mainshock Size?

Depending on the local rheology, this stress perturbation may relax either seismically in the form of aftershocks oraseismicallyin the form of post-seismic creep.
