Why so dangerous!

Tsunamis

WARNING!!

It's a very high, large wave in the ocean that is usually caused by an earthquake under the sea and that can cause great destruction when it reaches land

1- Difficult to predict and detect.2- The force of the water splashing on the shoreline is what makes them dangerous.3- They tear down houses and flood out places like people's homes and large buildings very easily.

Top tsunami prone countries/regions in the world?

• Albania • Chile • China • East Timor • India • Indonesia • Japan • Maldives • Mexico • Papua New Guinea • Peru • Philippines • Sri Lanka •Thailand • United States

How's the destructive nature of tsunamis measured?

- Wave Propagation - Warning Systems - Forecasting impacts - An instrument, known as Tsunameter, is anchored on the ocean floor and measures changes in water pressure when a tsunami passes above, developed by The Pacific Marine Environmental Laboratory.

2 Events........

Great Yaeyama Tsunami: In Yaeyama Islands, Okinawa, Japan On April 4, 1771 at about 8 A.M. Estimates of the highest seawater runup on Ishigaki Island, range between 30 meters and 85.4 meters. The tsunami put an abrupt stop to population growth on the islands, and was followed by malaria epidemics and crop failures which decreased the population further.

Pangandaran earthquake and tsunami:A 7.7 magnitude earthquake rocked the Indian Ocean seabed on July 17, 2006, 200 km south of Pangandaran, a beach famous to surfers for its perfect waves. This earthquake triggered tsunamis which height varied from 2 meters at Cilacap to 6 meters at Cimerak beach, where it swept away and flattened buildings as far as 400 metres away from the coastline. More than 800 people were reported missing or dead.
