In the early 1960s‚ the emergence of the theory of plate tectonics started a revolution in the earth sciences. Since then‚ scientists have verified and refined this theory‚ and now have a much better understanding of how our planet has been shaped by plate-tectonic processes. We now know that‚ directly or indirectly‚ plate tectonics influences nearly all geologic processes‚ past and present. Indeed‚ the notion that the entire Earth’s surface is continually shifting has profoundly changed the way

many different ways that tsunamis can form. One of them is by underwater earthquakes and underwater landslides. There are two kinds of underwater earthquakes‚ tectonic and subduction. When tectonic earthquakes occur‚ the seafloor becomes deformed‚ forcing displacement of water thus causing tsunamis. The other earthquake‚ subduction earthquakes act very differently. Tectonic plates slip under each other‚ creating a massive disturbance in the water and the land under it and also forces displacement of

The plate tectonic theory is the theory that describes large amounts of movements in the Earths lithosphere‚ whereby Continental and Oceanic crust is moved‚ destroyed and made from this. The idea of plate tectonics builds on other concepts such as continental drift‚ where continental plates over millions of years move‚ however the concept of continental drift was not accepted for some time‚ and there were many other theories to suggest that something else took place‚ as the idea of the earth moving

A tsunami are the effect of a natural primary hazards meaning that they are a secondary hazard‚ mostly the result of tectonic activity. The Boxing Day tsunami was caused by the subduction of the indo-Australian plate boundary underneath the Eurasian plate (240km off the coast of Indonesia). In contrast‚ the Japan tsunami was caused by the Pacific Plate subducting under the North American plate. The Asian and the Japan tsunami’s both

was a very violent earthquake of magnitude 9.3 on the Richter scale. It was the biggest earthquake ever recorded after the one in Chile on 22 May 1960‚ with a magnitude of 9.5. It originated at 00:58:53 GMT (7:58:53 AM local time)‚ on a fault in a subduction area between the Indo-Australian plate and the Burma plate (which forms part of the larger Eurasian plate (see fig. 1)‚ with the hypocenter at a depth of about 30 km‚ 160 km east of Sumatra. The coordinates of the epicentre are: latitude 3° 19’
