The 2011 earthquake off the Pacific coast of Tohoku was the most powerful earthquake in the history of Japan and it was, until now, considered the main reason for the tsunami waves that killed almost 20,000 people.

A Magnitude 8 earthquake created a tsunami that swept through several South Pacific islands last Wednesday. The tsunami killed at least 10 people through 5 villages and was reported to reach 1.5 m in height in places. See the embedded video!
