Because of their devastating potential, there is great interest in predicting the location and time of large earthquakes. This site explains that although a great deal is known about where earthquakes are likely, there is currently no reliable way to predict the days or months when an event will occur in any specific location. The Northridge and Parkfield earthquakes along with the Loma Prieta earthquake in Califonia are all associated with the San Andreas Fault and even though earthquakes on and near the fault are expected, there is no way to tell when and where the earthquake will occur. The one well-known successful earthquake prediction for Haicheng, China earthquake in 1975, when an evacuation warning was issued the day before a magnitude 7.3 earthquake is contrasted with the 1976 Tangshan earthquake, magnitude 7.6, which caused an estimated 250,000 fatalities.
