Debris from the Japan tsunami was hurled ashore in 2012 after an unusual earthquake.
Tsunamis are a series of massive waves that ripple out from the earthquake, volcanic eruption, landslide or underwater detonation that caused them. These huge waves can travel thousands of miles across ocean basins. While out at sea, wave heights are small, but as a tsunami approaches shore, the rise of the continental slope means water levels are shallower, and the wave begins to narrow and become higher.

Huge stresses beneath the surface moved plates of the Earth's crust hundreds of feet horizontally and dozens of feet vertically.
They could be repurposed for monitoring tsunamis, air pollution and global pandemics, scientists argue.
