Foreshocks
Some scientists have tried to use foreshocks to help predict upcoming earthquakes, but the 1975 Haicheng earthquake in China is one of the few successes. On the East Pacific Rise however, transform faults show quite predictable foreshock behaviour before the main seismic event. Reviews of data of past events and their foreshocks showed that they have a low number of aftershocks and high foreshock rates compared to continental strike-slip faults. (McGuire et al., 2005)
