Seismic Hazard Analysis Theory and Methodology

Sayed Hemeda*

Abstract

The probabilistic approach of earthquake hazard analysis aims at estimating the likelihood (probability) that any specified level of ground motion intensity will be attained or exceeded in an arbitrary future time period due to the trigger of earthquakes from potential seismic sources.

The analytical approach used to carry out probabilistic seismic hazard analysis is described in detail by Cornell, 1968; 1971; Esteva, 1969; Merz and Cornell, 1973; Cornell and Merz, 1975 and McGuire and Arabasz, 1990. The probabilistic seismic hazard assessment requires all the available information on seismicity and geotectonics of the examined region and regional attenuation characteristics of the ground motion as well as the adoption of a stochastic model for the forecasting of future earthquake occurrences.
