Not only one of the biggest earthquake in 20 years. The quake measuring 8.9 that occurred in Japan, on Friday (11/03/2011) afternoon, was recorded as the biggest earthquake in history that ever happened in the land of Sakura's. Throughout the record of seismicity in Japan, has not been that strong earthquakes.

Japan's deadliest earthquake in recorded occurred in 1891. The quake centered in Kanto was only measuring 7.9, but killed an estimated 140,000 people in the region around Tokyo. With a strength of 8.9, the last quake was far stronger than the earthquake in the Kanto, but not too large impact on the city of Tokyo.

"We estimate many casualties fell and widespread damage," said Kevin McCue, seismologists at the Central Queensland University in Canberra, Australia, as reported by ABC Web site on Friday. However, the number of victims in Tokyo in the Kanto region is not expected as many as 120 years ago because the epicenter is far north, about 376 km from Tokyo.

Japan is located in the path of the volcano or the Pacific Ring of Fire, including areas which are often affected by the earthquake. Several large earthquake data recorded in Japan is an earthquake measuring 8.5 on the Sanriku in 1896 that killed 27,000 people and caused tsunamis as high as 25 meters. In addition, the Kobe earthquake that occurred in 1995 measuring 6.9 on the Richter scale and killed 5502 people.

Japan quake measuring 8.9 on Richter scale this. The quake occurred at 14:46 local time and was centered 376 km southeast of Tokyo. This earthquake has caused tsunamis and potentially as high as 4 meters to 10 meters tsunami. Tsunami warning extended to the Pacific, the Philippines, and Indonesia.

Co-Director of the Australian Tsunami Research Center, Professor James Goff said the earthquake that occurred this time will be able to see the strength of Japan's earthquake-resistant buildings, the efficacy of the tsunami warning, and evacuation plans. "This event will be a series of tests to them all," he said.
