Japan's 20 volcanoes became alive after Tohoku EQ, expecting another 9.0

Japan’s Meteorological Agency on Friday warned that the country’s 20 volcanoes became alive due to the massive March 11 earthquake, and a study said earthquake over 9.0-magnitude might hit Japan again.

The Agency said volcanic explosion occurred after earthquake several times in history and people should maintain vigilance against this tendency.

The number of earthquakes above M 6.0 reached 77 on March. 74 out of them occurred in quake-hit region were aftershocks. The number is 50 times over the same period last year.

The largest aftershock on April 7 has killed 4 people, injured at least 166, and caused a power outage over 2.61 million households, according to Japan’s police officials.  The Meteorological Agency warned aftershocks above 6.0 M like the April 7 would probably hit Japan again.

Meanwhile, quakes of the  country’s 20 volcanoes occurred more frequently after the massive March 11 earthquake, especially, the FujiHakone, and Aso-San.

A massive 9.0 magnitude earthquake hit off the northeastern coast of Japan on March 11, 2011, triggering a massive tsunami which caused alerts to go up along the pacific basin.

The National Police Agency reported at 10:00 a.m., April 8, the death toll rose to 12,731.  The number of reported missing declined to 14,706. (Earth Issues)

Jacques Snyman | Siyavuna Development Centre commented on The Watchers: The massive earth changes that is becoming more and more apparent on a global scale is cause for great concern, especially if you're a city dweller. Learning how to grow your own organic foodstuffs, along with implementing this knowledge, is an important first step towards attaining some sort of basic self sustainability. Imagine the supermarket runs out of supplies tomorrow......what will you do?
