How important are "exact' fault dimensions in assessing seismic hazard at a near site? A case study for Shivta site, Israel

The definition of source zones is a standard element in seismic hazard analysis. Often, however, there may be considerable uncertainty regarding the actual fault dimensions. A methodology that enables analysts to quantify the implications of uncertain fault dimensions for assessed seismic hazard is presented. The methodology is applied to the Shivta site in Israel. The assessed hazard is quite insensitive to changes in the fault dimensions. -from Authors
