Indian Ocean buckled earth's crust is 10 meters

Earthquake December 26, 2004, with the epicenter in the Indian Ocean near the Indonesian island of Sumatra and the ensuing huge tsunami caused the death of more than 155 thousand people. And not only in Indonesia but also in the whole of Southeast Asia and even in Africa.

The tsunami in Southeast Asia, virtually all experts consider to be one of the worst natural disasters in recorded history. Caused him underwater earthquake measuring 9 on the Richter scale — the most powerful in the last 45 years: it was equivalent to the energy of explosion 9.5 thousand atomic bombs dropped on Hiroshima. It was enough that the axis of the planet shifted by 3 cm, and the Earth's rotation sped up by 3 microseconds.

Geological causes of the incident due to the fact that the island of Sumatra in the north-eastern Indonesia is on the border of the tectonic plates — huge areas of the earth's crust, staying in constant motion. Plate, on which the Indian Ocean, is moving to the north-east, gradually advancing to Sumatra.

Because it is heavier than the Sumatran, we can say that the Indian Ocean "sinking" under Sumatra. Crack length in the tectonic plate was about 1 thousand km, one of the plates fell almost 10 meters Tsunami 2006 proved: the tragedy of this kind does not know borders. According to the World Health Organization, up to 5 million people in the countries located in the Indian Ocean, have lost their livelihoods.

The waves of the Indian Ocean have been all over the Pacific and even touched the Kuril Islands. However, the power of the wave generated by an earthquake near about. Sumatra, put out numerous straits. Until about. Paramushiro on which stands the North Kuril, already sunk a harmless wave height of only 29 cm

Protect themselves, and even more impossible to prevent such disasters. However, it is humanly possible — to predict a tsunami. Russian experts from the Novosibirsk State University say: if it is underwater earthquake of 8 points, and is sure to be a tsunami. Question — where it comes.

To accurately calculate where you can expect the damage, the researchers simulated the situation on a computer. More or less adequate results can be obtained if a model is a multi billion computational cells. Today, the difference in the net accounts is 3-6 km, and it is necessary, it happens — 50 m So in predicting tsunamis, like it or not — it's up to supercomputers and new, faster, more algorithms account.
