Inventory Of The World'S Seventh Largest Earthquake Ever

Japan's 8.9 magnitude earthquake yesterday was the largest earthquake recorded in Japan in nearly 140 years, far exceeding the 1923 Kanto earthquake.

The US geological survey detected yesterday's

Japan is located in the circum Pacific volcanic belt. It is the intersection point of the 4 plates. Therefore, it has been threatened by earthquakes for many years. About 20% of the world's most powerful earthquakes occur in Japan.

It is estimated that in Japan, at least once every 5 minutes, there will be at least 2000 shocks every year.

The largest earthquake in Japan occurred in 1933. The intensity of the earthquake was 8.1. The epicenter was 290 kilometers away from the state.

More than 3000 people were killed in the disaster, but most casualties and damage were not caused by the earthquake itself, but by the tsunami triggered by the earthquake.

The most frequent earthquake in Japan was the Kanto earthquake in 1923, when the intensity of the earthquake was 7.9, and more than 140 thousand people died in Tokyo.

The earthquake and its fires destroyed more than 694 thousand houses. The earthquake also caused tsunami waves up to 12 meters in the bay of Xiang mo.

The 7.3 magnitude Kobe earthquake, which occurred in 1995, resulted in fewer casualties and more than 6430 deaths. However, it caused about 100 billion US dollars in economic damage, which has always been the highest loss of natural disasters.

Before yesterday's earthquake, the last two major earthquakes in Japan occurred in March and November last year, respectively, with an intensity of magnitude 6.6 and 6.9.

However, because the two earthquakes occurred in a certain distance from the state, it only caused some buildings in Tokyo to shake and did not cause any death.

The third largest earthquake occurred in 2004.

Other earthquakes larger than Japan's earthquake also included the Russian earthquake in 1952, the Peru earthquake in 1868 and the North American earthquake in 1700. The intensity of the three earthquakes was 9.

According to the US Geological Survey, the most powerful earthquake in history is the Chile earthquake of May 1960.

A 9.5 magnitude earthquake in the southern Chilean waters resulted in more than 1600 deaths and nearly 2 million homeless.

The American alas California suffered a magnitude 9.2 earthquake in 1964, and the earthquake also triggered.
