Tsunamis

A tsunami is a series of waves created when a body of water, such as an ocean, is rapidly displaced. Due to the immense amount of water and energy involved, the effects of tsunami can be devastating.

Signs of an approaching Tsunami
Their is often no advance warning of an approaching tsunami. However, since earthquakes are often a cause of tsunami, any earthquake occurring near a body of water may generate a tsunami. A tsunami is not a single wave but a series of waves, also known as a wave train. The first wave in a tsunami is not necessarily the most destructive.
Tsunami waves can be very long (as much as 60 miles, or 100 km) and be as far as one hour apart. They are able to cross entire oceans without great loss of energy.
About 80% of all tsunamis can happed in the Pacific Ocean. Tsunamis also can be caused by landslides, volcanic explosions etc .


How can I protect myself from a tsunami?

What to do Before and During a Tsunami

- Turn on your radio to learn if there is a tsunami warning if an earthquake occurs and you are in a coastal area.
- Move inland to higher ground immediately and stay there.
- Stay away from the beach. Never go down to the beach to watch a tsunami come in. If you can see the wave you are too close to escape it.

What to Do After a Tsunami
- Stay away from flooded and damaged areas until officials say it is safe to return.
- Stay away from debris in the water; it may pose a safety hazard to boats and people.
- Save yourself - not your possessions
