Well, the Pacific Rim on the western side is part of a tectonic plate affectionately referred to as the "Ring of Fire".  This is a huge plate that circles the better part of the Pacific Ocean.  There is a lot of subduction activity around the location of Japan, on the western side of the Ring of Fire.  This was illustrated most recently last summer as the plates shifted quite unexpectedly and cause a tsunamis of earth-shattering proportions that devastated the nuclear power supply plants on Japan's eastern shore.  A tsunamis is a huge wave generated by an earthquake type activity which causes a huge displacement of ocean water.  The waves produced by this displacement travel outwards in all directions and intensify when they near shore.  This tsunamis went very far inland, sweeping entire houses and cars back out to sea.
