damn weather

Was that the one you posted yesterday wondering whether there was already some melting?

 

I just hope the eruption doesn't start until sometime after 4:00 tomorrow (as I'm flying home from working in Sweden then

hi norfolk yep thats the one

 

heres the volcano info

 

Bárdarbunga, a large central volcano, had its last major eruption in 1477 when it produced a large ash and pumice fall-out deposit. It also produced the largest known lava flow during the past 10,000 years on earth (more than 21 cubic kilometers of volume).

Background:

The volcano is hidden beneath the northwestern part of the Vatnajökull glacier, and contains a 700-m-deep caldera that is hidden beneath ice and has extensive flank fissures, from where eruptions have taken place: the Veidivötn fissure extends for over 100 km to the SW, almost reaching Torfajökull volcano, while the Trollagigar fissure extends 50 km to the NE touching Askja volcano.A major risk from Bárdarbunga are jökulhlaups (glacier-outburst floods), that can be hazardous for areas in all directions around Bárdarbunga.

with the past there and the sheer amount of earthquakes and the harmonic reading its safe to say huge is possible

 

however will it break the huge ice there?

 

no-one really knows

 

but if it does it could be a biggie

Cheers John,

 

Thanks for the info

 

I'm most interested in Ash production.  Do you know, or can you point me to some documentation about ash production from Volcanoes?  I would have thought that water ingress would b much more likely to create ash than a 'dry' eruption.  We all know how water reacts with (extreme) heat, there's a hell of a lot of water in that glacier

hi norfolk

 

hope that helps

 

re the water reaction i agree that could be a problem.

been keeping an eye on this as will be a good source re the flood risk there

not perfect view but getting there

not perfect view but getting there

 

 

That looks to have progressed from the previous still featuring the melt water, is that a vent opened.?

[john pike]

hi lorenzo

 

very hard to tell and now the stills are too unclear to tell again

 

will post a clear one as soon as one appears though

[LincolnSnowstorm]

Wonder how long the web cam will last? ....if it blows! 

for example  http://www.jonfr.com/volcano/ Quote " The caldera is filled with 700 meter thick ice so an eruption in it would be extremely bad"

this is the cam for bardarbunga which is the main watch (its on the far right about half way up the screen)

 

cannot see it due to the weather

the link above and the pictures i am watching is from

Kverkfjöll volcano

this is because earthquakes are high there too and so are the harmonics

 

sorry for the confusion

Great link really insightful, this part is completely new to me, they plan to demolish roads ! Also looks like the build up on the Caldera is of some note.

 

"They wouldn't take it, all three bridges would be gone in an instant," he says. He adds that scientists cannot predict the scale of the floods, and that they may be smaller in scale. Right now equipment is being put into place to help break the roads and relieve pressure from the man-made structures if a managable flood was imminent.

So with one stage two and one stage four volcano do you think they are effecting each other and we could see two for the price one so to speak?

Liked this graph from @weather_king on Twitter.

 

Really tells it's own story..

Wow, the 1996 event is dwarfed by the current activity!

couple of images I saw earlier that I saved

nice 3d visual...notice small quakes as shallow as 600 meters ...just a case of waiting for big ones. http://baering.github.io/

erupting volcano off Japan could cause tsunami

Wednesday 20 Aug 2014 5:00a.m.

The small, but growing, island appeared last year and quickly engulfed the already-existing island of Nishinoshima (Reuters)

 

 

 

 

An erupting volcanic island that is expanding off Japan could trigger a tsunami if its freshly-formed lava slopes collapse into the sea, scientists say.

The small, but growing, island appeared last year and quickly engulfed the already-existing island of Nishinoshima, around 1000 kilometres south of Tokyo.

It now covers 1.26 square kilometres.

The island's craters are currently spewing out 200,000 cubic metres of lava every day - enough to fill 80 Olympic swimming pools - which is accumulating in its east, scientists said.

"If lava continues to mount on the eastern area, part of the island's slopes could collapse and cause a tsunami," warned Fukashi Maeno, assistant professor of the Earthquake Research Institute at the University of Tokyo.

 

He said a rockfall of 12 million cubic metres of lava would generate a one metre tsunami that could travel faster than a bullet train, hitting the island of Chichijima - 130kms away - in around 18 minutes, he said.

Chichijima, home to about 2000 people, is the largest island in the Ogasawara archipelago, a wild and remote chain that is administratively part of Tokyo.

quakes beween 12-1 on here really picked up

 

[john pike]

these were showing last night at 3am

not sure what this is showing
