Tsunami- an unusually large sea wave produced by a seaquake or undersea volcanic eruption.

A Tsunami is a series of waves that are caused by an underwater disturbance, such as an underwater earthquake. From the area of the disturbance, the waves travel outward in all directions causing ripples of waves. Earthquakes, Landslides, Volcanic Eruptions, Explosions, and Meteorites can also cause Tsunamis. Tsunamis can originate hundreds or even thousands of miles away from coastal areas. Areas at the greatest risk are those located 50 feet above sea level and within one mile of the shoreline. As the Tsunamis near the coastline, it grows to great height, and smashes into the shore causing a lot of damage. They are sometimes confused with tidal waves, even though they have nothing to do with tides.

Where do they occur?
Japan has suffered the most tsunamis in the world. Most tsunamis occur in the “Ring of Fire”, which is a zone of volcanoes and seismic activity.

Outdoor Safety Tips
· Watch the ocean for sudden low tide and exposure of the ocean floor.
· Watch out for trembling ground and ground rolling up and down in waves.
· If you are in a boat, stay at sea, far from shore.
· Listen to the radio for tsunami warnings and evacuation instruction.
· If you hear your communities’ sirens, evacuate as trained.
· Do not approach the ocean. Always seek the highest ground you can.
· Stay away from buildings that can topple.
· Stay away from bridges and other structures that could be washed away.

After the Tsunami Safety Tips
· Continue listening to NOAA Weather Radio, Coast Guard Emergency frequency stations.
· Stay out of buildings and homes that still have water remaining around it.
· When re-entering a home use extreme caution.
· Look for fire hazards, and gas leaks.
· Check to see if the building is stable.
· Open windows and doors to help dry the building.
