The occurrence of earthquakes, faulting of Pleistocene sediments, uplifting of Pleistocene coral reefs, recent incised wadis and lava effusions in addition to hot springs all clearly indicate that southeastern Saudi Arabia is tectonically active. This paper reviews the tectonic features of southwestern Saudi Arabia and provides new approaches and maps for the interpretation of old and recent earthquake data for improved assessment of the regional tectonics. A regionalized variable approach is used to develop earthquake groundmotion hazard maps for the region, based on geostatistical methods using the kriging technique. This hazard must be considered in any design/construction of engineering structures in the region. The application of kriging for estimating the ground shaking in the study region succeeded clearly in accomplishing its ultimate aim where the generated groundmotions are well correlated with the instrumental magnitude and historical intensity of any earthquake occurrence in the study region.
