ωнαт αяє тѕυηαмιѕ؟ • Tsunamis are series of waves in the ocean or another body of water caused by an Earthquake, Landslide, Volcanic eruption or Meteorite Impact. тѕυηαмι ƒα¢тѕ • 1. Many early geological, geographical, and oceanographic texts refer to tsunamis as "seismic sea waves." • 2. The Japanese translation for tsunami is 津波 • 3. The original Japanese term literally translates as "harbor wave." 4. Earthquakes, volcanic eruptions, underwater explosions, landslides, Earth movements, bolide impacts, and other disturbances above or below water all have the potential to create a tsunami. ∂ι∂ уσυ кησω؟ Did you know? Smaller earthquakes in Japan can start tsunamis that can only hit nearby coasts, but can also travel there in a few minutes. Did you know? Tsunamis have a small wave height offshore, and a very long wavelength which is why they generally don’t get realised at sea, forming only a slight growth mainly about 300mm above the normal sea level. They grow height when they reach shallower water. Did you know? There are only a few other languages that have a native word for this destructive wave. In the Tamil language the word is aazhi peralai, in the Acehnese language it is ie beuna or alon buluek. On Simeulue island off the western coast of Sumatra in Indonesia, in the Defayan language the word is semong also in the Sigulai language it is emong. ∂яαωвα¢к How does a Drawback occur? A drawback occurs because the tectonic plate on one side of the fault sinks during the earthquake, causing the overlaying water to move outwards with the smallest of the wave at its front. What is at Drawback? If the first part of a tsunami to reach land is a small wave called a drawback, rather than a wave crest, The water along the shoreline moves away dramatically, reveling normally hidden areas. ρι¢тυяєѕ!! тнє ιη∂ιαη σ¢єαη тѕυηαмι!! On December 26th 2004 an Earthquake of 9.3 on the richter scale struck off the Northwest coast, of the Indian island of Sumatra. Which triggered a tsunami, of 25 meters high and killed nearly 300,000 people. мσяє ƒα¢тѕ!! • 1. Tsunamis frequently happen in Japan approximately 195 times have been recorded. • 2. The 1960 Valdivia Earthquake, 1964 Alaska Earthquake and 2004 Indian Ocean Earthquake are recent examples of mega powerful earthquakes that created tsunamis that can cross entire oceans. • 3. A tsunami in the deep ocean has a wavelength of about 200 kilometers. • 4. About 80% of tsunamis occur in the Pacific Ocean, but can happen where there are large amounts of water, including lakes. вιвℓισgяαρну!! • http://en.wikipedia.org/wiki/Tsunami • http://www.ess.washington.edu/tsunami/Su matra.htm тнє єη∂ Thank you for watching my slideshow about Tsunamis!!!
