Earthquakes almost always cause great destruction on the wake of its path. The most recent major earthquake hit Japan with a magnitude of 8.9 which was later adjusted to a 9.0. And to make matters worse, it was followed moments after by a 10meter tsunami.

The United States Geological Survey has listed the largest seismic events since 1900 and the recent earthquake in Japan ranked in at 4th. Read more. http://earthquake.usgs.gov/earthquakes/world/10_largest_world.php
