This book provides an account of the 1987 Ecuador earthquakes, evaluating the physical phenomena involved and the performance of structures and systems. It identifies and recommends cases where an in-depth study would contribute to improvement of our ability to analyze and forecast such failures and our preparedness, warning, rescue, recovery, and rehabilitation systems. The volume also describes how state-of-the-art knowledge can be applied to improve public safety and welfare.
