Abstract

Three examples of landslides triggered by earthquakes have been examined to consider the natural variability of the slope forming materials, and the uncertainties surrounding input ground motions. These were the landslides at Villa Del Monte, California, Tachia Gorge, Taiwan and Las Colinas, El Salvador which were triggered by the Loma Prieta, (MW=7.0, 1989), Chi Chi, (MW=7.6, 1999) and El Salvador (MW=7.6, 2001) earthquakes respectively. The results of these analyses show a large scatter in the calculated factors of safety for earthquake conditions, some of which indicated stability when failure actually occurred.
