Information About

Foreshock




In particular, the East Pacific Rise Transform Fault s show foreshock activity before the main seismic event. Reviews of data of past events and their foreshocks showed that they have a low number of Aftershock s and high foreshock rates compared to continental Strike-slip Fault s. (McGuire ''et al.'', 2005)

The 9.5-magnitude Great Chilean Earthquake had a 7.9-magnitude foreshock.
