Tsunami

Tsunamis flood land and happen so quickly, they drown thousands. The power of tsunami waves destroy everything and everyone in its path, except for the few lucky ones who escape in time or find a way to survive. However, when it feels the entire ocean is sweeping over the land, escape can be nearly impossible to find.

Tsunamis

Tsunamis have occurred several times throughout history, including two fairly recent events. Friday, March 11, 2011, a magnitude 9.0 earthquake set off a tsunami that killed 15,883 people in Tohoku, Japan. This was the worst earthquake recorded in Japanese history. Another tsunami on December 26, 2004, struck eleven countries, including Sri Lanka and Indonesia. They believed it killed 169,752 people, but at least 127,294 were reported missing......................................................................................................................................................................................................................................................................................................................................................................................................................

Tsunamis are extreme ocean waves that surge to heights, sometimes 100 ft high, and fall over land. Most are caused by underwater earthquakes, landslides, and volcanic eruptions, though some have been caused by meteorites crashing into the sea. Meteorites or plate activity displaces and launches water that builds energy and height until it reaches land. Tsunamis are sudden, powerful, and often very deadly.

Most tsunamis occur in the Pacific Ocean's Ring of Fire, because of all the tectonic shifts happening there.

Though tsunamis occur quickly, the Pacific Tsunami Warning System uses seismic equipment and water level gauges to try and predict them as quickly as possible, and to measure the size and strength of the waves. This helps save lives, as does watching for warning signs (such as water close to shore being sucked out to see, which happens due to a vacuum effect the waves cause,) seeking higher ground, and not returning to vunerable areas until officials declare the land safe.
