Big Tokyo earthquake expected in the coming years


25/01/2012

The probability of a strong earthquake that occurs in the Japanese capital in the next few years, much more about this than official forecasts have warned, as the researchers note.

A team of scientists from the University of Tokyo reported that the probability of an earthquake magnitude of 7 points that will occur in the region over the next four years, reaching 75%.

The government, in turn, reported that the chances of recurrence of natural disasters over the next 30 years are equal to 70%. Warning authorities followed less than a year after the massive earthquake and tsunami devastated the northeast coast of Japan.

The last time the capital of Japan, Tokyo, has suffered from a great Kanto earthquake in 1923, when the tremors of magnitude 7.9 points claimed the lives of over 100,000 people, many of them burned on the fire. Earlier, in 1855, the city was also destroyed when the earthquake struck Ansei Edo.

Experts from the research center of seismic activity at the University of Tokyo have fulfilled their calculations, based on data from the growing number of aftershocks that occurred in the capital since then, as in northeastern Japan March 11, 2011 earthquake. Thus, according to the weather service, in March last year at the Tokyo and the surrounding area have been reported on average 1.48 earthquakes with a magnitude of 3-6 points a day. Experts note that it is about 5 times more than last year to the March disaster.

The researchers said that while "it is difficult to accurately predict" the impact of the impending disaster in Tokyo, but the government and citizens need to be prepared for anything.

Recall that the earthquake magnitude 9 points that occurred in Japan last year, also brought down the cooling system at a nuclear power plant "Fukushima", which caused some damage to the reactors.

Japan is located on the tectonic crossroads called the "Pacific Ring of Fire", which is why it is considered one of the most earthquake-prone countries in the world, and the Tokyo is situated in one of its most dangerous areas.

Huge city is located at the intersection of the Eurasian, Pacific and Philippine tectonic plates, between which there is a slow constantly rubbing against each other, which creates enormous seismic pressure.
