Earthquake For well-understood faults the probability that a segment may rupture during the next few decades can be estimated. Some heavy furniture moved; a few instances of fallen plaster. In the largest earthquakes whole districts can be devastated by the multiple consequences of ground shaking. The term probability refers to the likelihood of an event occurring. 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. However, the probability of an earthquake higher than Magnitude 6.1 to occur from the same source is low. For well-understood faults the probability that a segment may rupture during the next few decades can be estimated. 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. There is still a 50 percent chance for one or more magnitude 7.0 earthquakes In the San Francisco Bay Area in the next 30 years, and the probability of a repeat of the 1906 quake is significant. Within the next 30 years the probability is: 60% that an earthquake measuring magnitude 6.7; 46% that an earthquake measuring magnitude 7; 31% that an earthquake measuring magnitude 7.5; will occur in the Los Angeles region. 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. This provides the design spectral coordinates S DS and S D1. Earthquake Hazard Potential Effects of Shaking ; A/White : Very small probability of experiencing damaging earthquake effects. Several 5.0-plus seismic events in the two years preceding Loma Prieta also served as warnings.
