A tsunami is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and underwater explosions above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are in turn generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water from a large event.

Okawa Elementary School was an educational institution in Ishinomaki City, Miyagi Prefecture, Japan. The school was destroyed in the 2011 Tōhoku earthquake and tsunami. 74 of its 108 students, who had been sheltering in the school on the instructions of their teachers rather than evacuating to higher ground, were killed as the tsunami ran up the nearby Kitakami River. Only four of the students present when the tsunami struck the school survived. Ten of the school's eleven teachers also died. It was found that the school was unprepared for such an event, and that the scale of the tsunami had not been realized until it was too late.
