Tectonic shifts triggered by last year’s huge 9.0 magnitude undersea quake have left the chamber under 16 times the minimum pressure at which an eruption can occur, researchers said.
Researchers at the National Research Institute for Earth Science and Disaster Prevention studied the tectonic movements caused by the tsunami-triggering quake on March 11, 2011 and a magnitude 6.4 quake that rocked central Japan four days later, Kyodo News reported.
They estimated that 1.6 megapascals of pressure, equivalent to atmospheric pressure of some 15.8 kilograms per square centimetre (226 pounds per square inch), was being exerted on the magma chamber.
Volcanic eruptions can be triggered by as little as 0.1 megapascals of pressure, and the reading of 1.6 megapascals is “not a small figure”, said senior researcher Eisuke Fujita, according to Kyodo.

JAPAN – Up to 323,000 people could die if three earthquakes occur simultaneously along the Nankai Trough, killing about 70 per cent of victims in subsequent tsunami, according to new predictions by two Cabinet Office panels.
The panels on Wednesday released predictions of damage that would be caused by a magnitude-9 Nankai Trough triple quake. This is the largest triple quake expected to occur in the trough–which stretches from off Shizuoka Prefecture down to Shikoku and Kyushu–with the so-called Tokai, Tonankai and Nankai earthquakes happening simultaneously.
The size of the predicted focal area is twice that of the magnitude-8.7 triple quake predicted by the government’s Central Disaster Management Council in 2003.
One of the study panels was tasked with estimating the height of tsunami and the area of inundated regions, while the other was a Read more…
The Ring Of Fire Is Roaring To Life And There Will Be Earthquakes Of Historic Importance On The West Coast Of The United States
Does it seem to you like there has been an unusual amount of seismic activity around the world lately? Well, it isn’t just your imagination. The Ring of Fire is roaring to life and that is really bad news for the west coast of the United States. Approximately 90 percent of all earthquakes and approximately 75 percent of all volcanic eruptions occur along the Ring of Fire. Considering the fact that the entire west coast of the United States lies along the Ring of Fire, we should be very concerned that the Ring of Fire is becoming more active. On Wednesday, the most powerful strike-slip earthquake ever recorded happened along the Ring of Fire. If that earthquake had happened in a major U.S. city along the west coast, the city would have been entirely destroyed. Scientists tell us that there is nearly a 100% certainty that the “Big One” will hit California at some point. In recent years we have seen Japan, Chile, Indonesia and New Zealand all get hit by historic earthquakes. It is inevitable that there will be earthquakes of historic importance on the west coast of the United States as well. So far we have been very fortunate, but that good fortune will not last indefinitely.
In a previous article, I showed that earthquakes are becoming more frequent around the globe. In 2001, there were 137 earthquakes of magnitude 6.0 or greater and in 2011 there were 205. The charts and data that I presented in that previous article show a clear Read more…
Though it was the season when Mt. Fuji has the most snow, snow is already disappearing.
From December to January, most of the snow melted only within a month. Mt. Fuji is heated.
Citizens near Mt. Fuji talks they haven’t seen such a thing.
A senior Chinese Foreign Ministry official on Wednesday lashed potential U.S. plans to collaborate with partner nations in developing a ballistic missile shield covering Asia, China Daily reported (see GSN, March 27).
U.S. Assistant Defense Secretary Madelyn Creedon in March said the Obama administration was discussing cooperative missile defense with Australia, Japan and South Korea, according to earlier reporting. Any antimissile system for the region would be based on the developing U.S. “phased adaptive approach” program to deploy land- and sea-based missile interceptors around Europe, Creedon told lawmakers.
“The Chinese government always insists that (countries) should start by maintaining global strategic stability and promoting strategic mutual trust between major powers to handle the issue of missile defense prudently,” according to Luo Zhaohui, Asian affairs chief for the Chinese Foreign Ministry.
“Building a missile defense system in the Asia-Pacific region will have negative effects on global and regional strategic stability, and go against the Read more…
Two Russian anti-submarine aircraft have flown over a Japanese destroyer preparing to shoot down a North Korean rocket if it passes over Japan’s territory, a Japanese TV channel reported on Wednesday, citing the country’s Defense Ministry.
According to the ministry, the Il-38 planes were seen on Tuesday off the south-west coast of the largest Japanese island of Honshu, where the destroyer is currently based. The ministry said that Japanese fighters accompanied the IL-38s during their flight.
The NHK TV channel suggested that the Russian planes had been collecting information on the multi-purpose combat system Aegis which is installed on the destroyer. Russian patrol aircrafts have been spotted performing reconnaissance missions, without Read more…
A Japanese bank will introduce ATMs that use palm scanners in place of cash cards, it said Wednesday.

Ogaki Kyoristu Bank said the new machines will allow customers to withdraw or deposit cash and check their balances by placing their hand on a scanner and entering their birthday plus a pin number. The ATMs will initially be installed at 10 banks, as well as a drive-through ATM and two mobile banks, from September.
Ogaiki announced the new ATMs with the slogan “You are your cash card.”
One reason the bank decided to use the new technology was the massive earthquake and tsunami that ravaged the country’s northeast coast last year, it said. Many who escaped the tsunami lost their homes, personal possessions and all forms of identification, and so were unable to access their bank accounts until weeks or months later.
Finger and palm scanners are currently used by many large Japanese banks along with cash cards as an additional safety feature, but Ogaki said it will be the first bank in the country to do away with cards Read more…
