In the largest earthquakes whole districts can be devastated by the multiple consequences of ground shaking. You can calculate an event's probability with the following formula: ... How about one on an earthquake fault? An earthquake is a shock wave that radiates to the Earth's surface from underground. The Federal Democratic Republic of Nepal lies in one of the active continental collision zone of the world, the Himalaya, where the probability of Earthquake occurrence is very high. In 2007, earthquake scientists led by the USGS, CGS, and SCEC estimated that there is a 63% probability of a magnitude 6.7 or greater earthquake in the Bay Area in the next 30 years. This represents a High relative risk. Several 5.0-plus seismic events in the two years preceding Loma Prieta also served as warnings. Damage slight. The current estimates of the probability of a major earthquake on any of the numerous regional faults range up to 70 percent within the thirty-year period 2000–2029. USGS has estimated that there is a Los Angeles earthquake probability of a 75% likelihood of one or more magnitude 7.5 or greater quakes striking in the next thirty years, as of 2014.
