6.9 : 2012/03/14 Time 09:08:38 Earthquake Details USGS
A 6.9-magnitude earthquake jolted the Pacific side of Hokkaido and north-east Japan regions on Wednesday, reports quoting the U.S. Geological Survey and Japanese Meteorological agency said.
The 6.9 quake registered 4 on the Japanese seismic intensity scale of 7 in the Kushiro area of southern Hokkaido, and in parts of Aomori and Iwate prefectures, according to the Japanese agency.
The quake, originating at a depth of 26.6 kilometer, was centered about 270 kilometers off the coast.
The Japanese Meteorological Agency issued a tsunami advisory, warning of a half-meter wave, but canceled it shortly. So far, two waves measuring 20 and 10 cm respectively reached the Japanese coast, according to NHK TV channel.
Later in the day, another quakes struck near the epicentre of Wednesday’s jolt, but there was no tsunami warning following the latest tremor, the USGS and Japanese authorities said.

There were no immediate reports of damage, Japanese media reported. Kyodo news agency says the earthquakes have reportedly left Japan’s nuclear facilities unscathed. A spokesman for Tohoku Electric Power, which operates two nuclear power plants in the country’s northeast, said the facilities were unaffected.
However, it advised to “pay attention when fishing, swimming or engaging in other activities, as there may be still slight sea-level changes for the time being.”
On Sunday, Japan marked the first anniversary of an earthquake and tsunami that killed thousands in the country, and triggered the world’s worst nuclear crisis in a quarter century.
Sakurajima Volcano in Japan — Earthquake on Camera then large eruption
Sakurajima continued its second day of violent eruptions on Tuesday, spewing hot rocks and ash, but there was no major damage in the vicinity, the Japanese Meteorological Agency said.
The agency said Monday’s powerful eruption was the most forceful since 2009.
The volcano is located in the southern prefecture of Kagoshima.
The Meteorological Agency added that the volcano has been erupting steadily for the last two years, but the eruption on Monday turned violent, throwing 50-centimetre (1 foot 6 inches) rocks nearly 1.2 miles away, the furthest since 2009.
The volcano has already had over 300 eruptions this year.
Notice the lower left camera.. and lower right camera.. clearly showing a noticeable earthquake — then an explosive daytime eruption… which revealed a steam vacuum pressure blast.
The vacuum in the blast was revealed by the steam in the caldera as it was forced up, and then sucked BACK into the caldera — in less than 1 second !
