December 12, 2008 - Four years ago a massive earthquake near the coast of Sumatra set off a tsunami that killed more than 225,000 people in countries as far away as Sri Lanka and Thailand. A recent report in Science Magazine (subscription required) infers earthquake supercycles from sea level changes recorded in the region's corals. In view of these supercycles scientists predict that there is a high likelihood of another hugely destructive earthquake and tsunami in the next 20-30 years. A fault line running by the Mentawai Islands is the most likely epicenter. The 2004 tsunami was caused by an earthquake under the seabed that produced waves up to 100 ft high.
