simulated aftershock sequences for an m 7.8 earthquake on the ...

Aftershocks are allowed to be up to 1,000 km away from their mainshock, but are rarely generated at such large distances due to the inverse power law decay of aftershock density.

The Wonderful World of Aftershocks

Aftershocks are often seen as small, unimportant earthquakes •The National Hazard Map and engineering codes ignore them! •But aftershocks are important!

The Spatial Density of Foreshocks

If the spatial decay of r- is generated by aftershocks, then 33 why is it present before the mainshock? I will follow up the observation by showing that a 34 statistical seismicity model in which aftershocks follow the spatial decay law of r- automatically 35 generates foreshocks with the same ...

Ben-Zion and Lyakhovsky developeda solution for aftershocks decay in a damage rheology model. The solution indicates that the productivity of aftershocks decreases with increasing value of anon-dimensional material parameter R , given by the ratio of timescale for brittle deformation to ...

Aftershock moment release rates, computed by summing aftershock moments intime intervals, follow a power-law time dependence similar to Omori'slaw from minutes to months after the mainshock; furthermore, in contrast to the previously observed saturation in numbers of aftershocks shortly after ...
