On the morning of December 26, 2004, at 0058 UTC a 9.2 magnitude earthquake occurred off the northern coast of Sumatra. This initial quake, the second largest in recorded history, triggered a 10 minute cascade of tremors along the plate boundary in the Indian Ocean for 1200km. It is estimated the plates shifted 10m laterally and 5m vertically resulting in a release of energy and water displacement equal to 100 gigatons of TNT. The tsunami that followed affected 14 countries and killed over 200,000 people. It completely circled the globe and is believed to have caused the Earth's rotation to wobble 1 inch.
