Project on tsunami for class 10 sst?

Answer 1

Well one conclusion is to not listen to a word Ian says, it's utter BS

tsunami are a major threat to us as we tend to live by the sea in large numbers many of the world largest cities are either on the coast or on rivers a short distance inland, in terms of tsunami we have had a pretty easy ride in modern times till 2004 when we were shown the devastation they can cause, I guess Ian thinks 300,000 deaths is funny, and the more recent Japanese disaster.

Look at a little history though and you find these have happened many times It is now very likely the Minoan Civilization was decimated by a tsunami, when the volcano on Santorini erupted, the Romans and Greeks new of and described tsunami. Further back in history Hawaii is known to have been the cause of at least half a dozen mega tsunami caused by landslides of it's steep sided and unstable volcanic soils, the waves from these events are thought to have been 1000 to 1500m high so tsunami do not always require an earthquake as the trigger evidence shows at least one of these hit the coast of the U.S. another cause is impact from asteroids given that the surface of the Earth is 70% water any such impact is more likely to be in water depending on size these can produce waves as large or larger than the Hawaiian ones.

The largest known modern tsunami happened in Alaska in 1958 in Lituya Bay caused by an earthquake, luckily it was contained by the bay, but the wave created was over 500m high two fishermen were killed and two others actually managed to ride the wave and survived, that would have been one heck of a ride. As a guide the Empire State Building is 443m high.

Answer 2

it can not be made but i will help write about what are the causes,which are the places effected

Answer 3

The area of science that explains tsunami causes and effects is physics. Further divisions can be made into geology, tectonics, hydrology, and fluid dynamics.
