Aftershock Studies
Aftershock Studies can help answer important questions about the mainshock. Is the location determined from regional data acurrate? What is the orientation of the fault plane? How large an area ruptured?
Aftershock studies answer questions related to earthquake occurrence. What is the state of stress in the crust?
Aftershock studies answer questions about ground motion attenuation and site response for seismic hazard. What are the magnitudes of the aftershocks? What are local Q and kappa values for deep soils? What is the average site response for deep soils?
