How many aftershocks can you expect after an earthquake? Globally, the probability one earthquake will be followed by a large earthquake within 3 days is somewhere just over 6%, according to USGS ...
In seismology, an aftershock is a smaller earthquake that follows a larger earthquake, in the same area of the main shock, caused as the displaced crust adjusts to the effects of the main shock. Large earthquakes can have hundreds to thousands of instrumentally detectable aftershocks, which steadily decrease in magnitude and frequency according ...

An aftershock is an earthquake that occurs after a previous earthquake, the mainshock. Rapid changes of stress between rocks, and the stress from the original earthquake are the main causes of these aftershocks, [34] along with the crust around the ruptured fault plane as it adjusts to the effects of the mainshock.

Earthquake modification techniques and modern building codes are designed to prevent total destruction of buildings for earthquakes of no greater than 8.5 on the Richter Scale. [4] Although the Richter Scale is referenced, the localized shaking intensity is one of the largest factors to be considered in building resiliency.
After an earthquake, the OES advises those affected by the earthquake to: Be alert to other possible hazards such as downed power lines. Expect possible aftershocks.
San Francisco Bay after an earthquake on Thursday, December 5 (Reuters) If you are feeling a noticeable earthquake, it is advised that you drop down onto your hands and knees before the shaking ...
A foreshock is an earthquake that occurs before a larger seismic event (the mainshock) and is related to it in both time and space. The designation of an earthquake as foreshock, mainshock or aftershock is only possible after the full sequence of events has happened. [4]
