Japanese Volcano - Sakurajima - Erupts Again. March 23, 2011

On Search live-cam: Sakura-jima (Japan)

Interesting to watch.

...I do find it difficult to understand why some people say volcanic activity is NOT related to earthquake activity. Seems fairly obvious.

...very interesting

S&F.....agree with you on how people can't see the connection....

Why wouldnt they be? Both operate off of the high pressure of magma, and when it rises to the surface (like a viagra laced night out with ole charlie sheen on hollywood blvd in search of coked up shims) it makes volcanos blow, or the earth rattle.

I am not showing any sources reporting this.... twitter doesnt have a whole lot if anything either.

I was wondering.. do you know if this volcano erupts much? Are you worried about it? just curious...thanks..

major explosion now

is this a live link? and thanks for sharing

yes it is

and you are welcome

Thanks for reposting the live link from the OP.

...That webcam is down now - can't find anything on youtube - did you get the new eruption on video?

...Hope so!

Seems fairly clear to me that earthquakes and volcanic eruptions can be related, and result from similar processes (depending how they're tweaked).

I think Sakura-jima's ongoing eruptions are important because of all the nuclear reactors in Japan - and think it's monumentally stupid to put nuclear reactors in geophysically unstable areas.

Wanting to drive that point home. Plus, I just like volcanoes.

I was thinking the same thing. What ever possessed them to build Nuke Plants on such un-stable ground?? I thought they were a smart people?

Are you suggesting the eruptions - which started in January - caused the later earthquake elsewhere in Japan?

No. ...Just that the same dynamics that cause earthquakes might also trigger volcanic eruptions. But who knows? All I think is that it's all related - and we muck about with things at our own peril.

Never under-estimate the power of the almighty dollar.

...Maybe some US-led corporate-government consortium strong-armed the Japanese after WWII into spearheading some nuclear power project or another. ...What's the history of the development of the nuclear power industry?

That's interesting what you say... I'll have to look into that. As smart as the Japanese are no matter who made who do what... you would think they would still plan to build it on stronger/stable ground. I use to live in a town called Midland Mi.. they have a NUKE plant there.. to my knowledge is was built and to this day... nonoperational!


If a Nuke plant was built 30yrs ago... but never ran... does it still pose a huge danger? just curious...

thanx

I thought it was common knowledge that quakes triggered or were precursors to volcanic events. Yes, I know public school in the US is pretty much brainwashing and conditioning, but that is something I was taught in grade school clear through highschool. We covered the same topic in a Geology Class I took in College a few years back. There is definitely a link between volcanoes and earthquakes. If you don't believe that you haven't opened a science book in the past quarter century. I think it's clear that the two geologic events are directly connected.

Could you PLEASE post some references?

There's now a running debate about this on ATS, and in the scientific community. The naysayers probably get their funding from corporate sources, but their bull puckey is all over.

Please do - and let us know what you find!

Depends how far they got, and whether or not there are radioactive materials present.

Yeah let me gather some data here. I think I still have that Geology book from my college class too. I'll get back ASAP, sorry for not including any sources I just thought it was a pretty common knowledge... Surprises me that there is even a debate about it.

I'll return no worries, I'd do it now but I'm at work so I don't have the time to dedicate to the research atm.

Hmm it seems I am having some trouble finding a legitimate source.

I found the following article HERE:


"SEISMIC TRIGGERING OF ERUPTIONS IN THE FAR FIELD: Volcanoes and Geysers"

Annual Review of Earth and Planetary Sciences
Vol. 34: 263-291 (Volume publication date May 2006)

I can't read it because I don't have a subscription, but in the abstract it states the following :

Approximately 0.4% of explosive volcanic eruptions occur within a few days of large, distant earthquakes. This many “triggered” eruptions is much greater than expected by chance. Several mechanisms have been proposed to explain triggering through changes in magma overpressure, including the growth of bubbles, the advection of large pressures by rising bubbles, and overturn of magma chambers. Alternatively, triggered eruptions may occur through failure of rocks surrounding stored magma. All these mechanisms require a process that enhances small static stress changes caused by earthquakes or that can convert (the larger) transient, dynamic strains into permanent changes in pressure. All proposed processes, in addition to viscoelastic relaxation of stresses, can result in delayed triggering of eruptions, although quantifying the connection between earthquakes and delayed, triggered eruptions is much more challenging. Mud volcanoes and geysers also respond to distant earthquakes. Mud volcanoes that discharge mud from depths greater than many hundreds of meters may be triggered by liquefaction caused by shaking, and may thus be similar to small mud volcanoes that originate within a few meters of the surface. Changes in permeability of the matrix surrounding main geyser conduits, by opening or creating new fractures, may explain the observed changes in their eruption frequency.

So it sounds like there is a link, but they can't quite put their finger on it. Maybe I'll get a subscription so I can view the pdf. I guess I was thinking more along the lines of seismic activity being related to volcanoes.. It is easy to get seismic activity and earthquakes mixed up I suppose. Several reports show that there is an increase in seismic activity before volcano eruption. I'll keep digging if there is more interest.
