Strong quake hits central Japan, with minor tsunami observed

TOKYO — A strong 6.6-magnitude earthquake struck central Japan early Tuesday, with minor initial waves of tsunami observed in the region, the meteorological agency said.

The quake hit at 5:07 am (2007 GMT) at a depth of 20 kilometres (12 miles) in the Pacific off Shizuoka prefecture, west of Tokyo, the Agency said.

"I felt both strong horizontal and vertical shaking," Atsushi Imai, a city official at Izu, eastern Shizuoka, told Japan's public broadcaster NHK.

"It was so strong that I have never experienced before," Imai said. "Light objects fell from shelves. I have not seen signs of any major damage for now."

As an observed tsunami, the ocean surface surged by some 40 centimetres (16 inches) at Omaezaki, Shizuoka, the weather agency said.

The Hamaoka nuclear plant in Shizuoka made an immediate halt at operating two nuclear reactors due to the quake, the Chubu Electric Power Co. said.

"The reactor number four and five made an emergency stop. No abnormalities are seen at the plant," said a company official.

The quake also rocked buildings in Tokyo, but no damage was reported in the capital.

Around 20 percent of the world's most powerful earthquakes strike Japan.

Speaking of Tokyo earthquakes, Here 's an acct of the 1923 Great Kanto quake(kanto is the level plain on which Tokyo was built .
Japan has a long tragic history of QE's since time immemorial, and today the Japanese are as advanced in EQ prep as any country. Sitting at edge of two tectonic plates directly above a subduction zone makes japan an extremely active zone for EQ's

The 1923 Great Kantō earthquake (関東大震災, Kantō daishinsai?) struck the Kantō plain on the Japanese main island of Honshū at 11:58:44 am JST on September 1, 1923. Varied accounts hold that the duration of the earthquake was between 4 and 10 minutes.

The quake had a magnitude of 8.3 on the Richter scale, with its focus deep beneath Izu Ōshima Island in Sagami Bay. It devastated Tokyo, the port city of Yokohama, surrounding prefectures of Chiba, Kanagawa, and Shizuoka, and caused widespread damage throughout the Kantō region.[1] The power and intensity of the earthquake is easy to underestimate, but the 1923 earthquake managed to move the 93-ton Great Buddha statue at Kamakura. The statue slid forward almost two feet.[2]

Casualty estimates range from about 100,000 to 142,000 deaths, the latter figure including approximately 40,000 who went missing and were presumed dead. According to the Japanese construction company Kajima Kobori Research's report of September 2005, there were 105,000 confirmed deaths in the 1923 quake.[3][4][5]
