Analysis of the Sumatra-Andaman Earthquake Reveals Longest Fault Rupture EverThe great Sumatra-Andaman earthquake was an event of stunning proportions, both in its human dimensions--nearly 300,000 lives lost--and as a geological phenomenon. The sudden rupture of a huge fault beneath the Indian Ocean unleashed a devastating tsunami. It was the largest earthquake in the past 40 years and was followed by the second largest just three months later on March 28, 2005.

The new analysis gives the Sumatra-Andaman earthquake a seismic magnitude of at least 9.1, and possibly as high as 9.3. Earlier estimates had put it at magnitude 9.0. By comparison, the 1960 earthquake in Chile was magnitude 9.5, and the 1964 Alaska earthquake was magnitude 9.2.
