That part of the earth’s solid crust closest to the surface is called bed rock. The size of the ground motion experienced at the earth’s surface is affected by the geology of the material between bed rock and the surface. "Level of Confidence" is generally used in the context of deterministic loss estimates. In a deterministic analysis, once it has been assumed that the scenario earthquake occurs, it is common to associate a level of confidence with the loss to the building(s). Typically, a 90 percent confidence level is used for the loss estimate.An earthquake is a violent and abrupt shaking of the ground, caused by movement between tectonic plates along a fault line in the earth’s crust. Earthquakes can result in the ground shaking, soil liquefaction, landslides, fissures, avalanches, fires and tsunamis.
