U22B: The 2004 Sumatra Mega–Earthquake: Lessons From a Monster
Presented by Emile Okal, Northwestern University
Marriott, Yerba Buena, Salon 9
1300h

The Sumatra–Andaman earthquake of 26 December 2004 was the largest one in 40 years, and perhaps since the great Chilean earthquake of 1960. The death toll due to the Indian Ocean tsunami is unparalleled in recorded, and probably absolute, human history. Most significantly, it was the first mega–earthquake to occur since the explosion of information technology revolutionized both instrumentation and dissemination of data. The tsunami was recorded by technologies as diverse as satellite altimetry, broadband seismometers, infrasound, and hydroacoustic sensors, none of which was designed for that purpose. The location of the earthquake caught most of the seismological community by surprise, and has led to a humble reassessment of our vision of the seismic potential of subduction zones. The size of the earthquake was difficult to fully assess, especially in real or quasi–real time, simply because most software had never been designed to consider the relevant source durations and frequency bands. This has led to critical reviews of operational tsunami warning algorithms, and to innovative suggestions for the synergetic use of multiple technologies in this respect. From the social and engineering points of view, data gathered in the course of a comprehensive, and still ongoing, program of field surveys have revealed intriguing patterns in the delayed response of distant harbors, as stressed by the need for the continued education of communities worldwide to the hazards inherent in living in, or simply visiting, coastal areas.
