Abstract
This paper reports on the effects of the great Sumatra earthquake and tsunami of December 26, 2004, in and around Port Blair, the capital city of the Andaman and Nicobar Islands, India. The earthquake shaking and subsequent tsunami caused substantial damage to structures that include buildings, harbors, overhead water tanks, seaport control towers, and so on. Other important structures, for example, dams, bridges, hangars, and so on, also suffered minor damage without disrupting their functioning. Reinforced concrete structures on the islands were the worst performers, while traditionally constructed timber and masonry structures performed well in response to ground shaking. The mandatory Indian Standards were not complied within the design of many recent structures on the islands located in the most severe seismic zone in India.
