Pressure in Mount Fuji is now higher than last eruption, warn experts

Mount Fuji 'under more pressure than last eruption'

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.

So in 1707, was it a big one, like a doom explosion.

If not, nothing to see here folks

Maybe I'm missing something...but how would they have measured this in 1707, much less have a record of it that survived this long?

From Global Volcanism Program


The conical form of Fuji-san, Japan's highest and most noted volcano, belies its complex origin. The modern postglacial stratovolcano is constructed above a group of overlapping volcanoes, remnants of which form irregularities on Fuji's profile. Growth of the Younger Fuji volcano began with a period of voluminous lava flows from 11,000 to 8000 years before present (BP), accounting for four-fifths of the volume of the Younger Fuji volcano. Minor explosive eruptions dominated activity from 8000 to 4500 BP, with another period of major lava flows occurring from 4500 to 3000 BP. Subsequently, intermittent major explosive eruptions occurred, with subordinate lava flows and small pyroclastic flows. Summit eruptions dominated from 3000 to 2000 BP, after which flank vents were active. The extensive basaltic lava flows from the summit and some of the more than 100 flank cones and vents blocked drainages against the Tertiary Misaka Mountains on the north side of the volcano, forming the Fuji Five Lakes, popular resort destinations. The last confirmed eruption of this dominantly basaltic volcano in 1707 was Fuji's largest during historical time. It deposited ash on Edo (Tokyo) and formed a large new crater on the east flank.

Thats what I was thinking...

[link to www.tipsofallsorts.com]

The earthquake measuring device in the link was made by the Chinese in 132AD. I have actually seen one of these work in San Fansisco, CA it worked at a 1.0 EQ I think that is pretty good for those dumb Chinese people in 132AD........

So here you go this is an EQ measuring device from 132AD. It piced up a quake in 135AD 600 miles away. Those dumb Chinese people that dare challange our electronice from 132AD. Think about it!

They measured it from space I think

IWTB - Looks like we have lot of dormant volacanos suddenly becoming active. Have you researched on this ? any reasons?

Is this a super volcano?

We just give him a Diaper like we done
with Fuko-Boy, oh my God that was
soooooooooo smelly!

I would not be surprised to see him
belching.

crustal earth displacmemt, the mother of ALL DOOM.....

not good. just like all the other things going on geologically lately.

How big was the last blow off?

My biggest fear is that Mt Fuji might erupt sideways like Mt St Helens did.

If it erupted sideways towards Tokyo (100 kms away), and the volcano caused a very large pyroclastic flow towards Tokyo it would be a massive disaster.



I hope it doesn't happen because the death toll would be huge.

Not good for Japan. They just can't catch a break!
Although, they did invade my people's land, murdered my mother's biological family, and cause my mother to live 4 years in a Korean orphanage.

Good find..Maybe a "Release of back pressure"
is needed for a "HAPPY ENDING" for this potential Doom. But really.. A Multi megaton explosion of Fuji would be disastrous to the surrounding area. What used to be farmland is now industrial areas.

Mt Fuji erupted every 30 years in the past and it has been 300 years. This could be the BIG ONE.

Yes it does look like it will be a big one, especially with those very high pressure measurements !

But, will it happen in our lifetime ? It waited 300 years, who's to say it won't wait another 30 or 40 ?

Basically what we know about volcanoes is exactly how much we now about earthquakes...which is squat !

Yes a big Mt Fuji eruption "could" be major DOOM

If the current pressure is 16 times the minimum needed for an eruption to occur ... what is preventing the volcano from erupting? Especially since 16 times is a huge amount of pressure!

HAARP

It'll be great to watch!!

Spectacular!!

Great catch!!! Not so good to Japan...

How would they know if the pressure is higher than it was in 1707? Was there even the ability to know that kind of thing back then?

What movie is that from?
Love the special effects.
