NOAA / Public Domain
  • The Japan Trench is a deep-sea trench east of the islands of Japan. The trench formed as the Pacific Plate subducted, or sank, below the Okhotsk Plate. The two plates continue to move toward each other. This movement can cause devastating earthquakes in Japan, such as a magnitude 9.0 earthquake that occurred on March 11, 2011.
