Whoops-did I not explain too well about what happened in Japan?
So what happened in Japan was something that was called "Subduction" between two two tectonic plates. The Pacific plate and the Eurasian plate are the key players here. The Pacific Plate slid underneath the Eurasian Plate, which created a tremor that we call an earthquake. But, what caused the most damage was the tsunami that the earthquake triggered.

As you can see in the above diagram, the Pacific Plate slides under the Philippine Plate. The Pacific Plate is the "subducting" plate, while the Philippine Plate is the "overlying" plate. the Pacific Plate pushes the Philippine Plate up, which is an earthquake.
A neat fact about Subduction Zones: They are more prone to volcanoes and major earthquakes! No surprise there! Japan got hit by a major earthquake!
I hope you learned a little more about Plate Tectonics! I'll be blogging more about Plate Tectonics and my trip around the world soon! With the conclusion of Japan, we are off to the Himalayas! See you there!
(Of course, since we are underage, we cannot climb the Himalayas, so we'll settle for a day or so of sightseeing around the Himalayas and more knowledge about Tectonic Plates!)
Nice diagram of the type of boundary, and i like the fish at the bottom too
