Trace of the fault rupture that appeared in the 1999 ChiChi Earthquake, Taiwan, closely followed the frontal slope of the north-south-trending mountain range. Foundations for major roads running along the fault have suffered serious damages. When embedded foundations bearing superstructures are forcibly shaken, their top ends can be cracked due to large inertia forces from their superstructures, and with these plastic hinges formed, the entire structure will then experience large soil deformations. The sequence of failures will be thus a key to estimate performances of these structures near active faults. Meanwhile, the 2005 Kashmir earthquake, Pakistan, formed a great number of debris sources along their activated faults. Heavy rains in the monsoon of 2006 that followed the Kashmir earthquake were responsible for raising river beds by several meters.
