Japan was jolted by a 8.9 magnitude earthquake on Friday, March 11th at 2:46pm local time. At the time of this posting, the LA Times is reporting over a 1,000 fatalities from the earthquake and tsunami that followed. This earthquake is the most powerful earthquake to hit Japan in recorded history. The earthquake occurred as a result of thrust faulting on or near the subduction zone interface plate boundary between the Pacific and North America plates. The earthquake was centered in the Pacific Ocean near the East Coast of the main Japanese island of Honshu. More than 50 aftershocks followed, with the strongest measuring 7.1. Scientists said the quake ranked as the fifth-largest earthquake in the world since 1900 and released nearly 8,000 times more energy than one that devastated Christchurch, New Zealand, last month. There is no estimate of the amount of monetary loss as a result from this disaster at this time.

Exponent has compiled a list of technical, relief, and news information about the earthquake and tsunami.
