Volcano watch 2010

reply to post by PuterMan


Thanks for the info.

I'm just wondering if all of this 'caldera' action is making anyone a little anxious? I don't mean doom and gloom or all that drama, but just the fact that (it seems) suddenly we have several different calderas either becoming active or stirring at the same time? I still hold a firm belief that ALL of the volcanic activity on our planet is connected at some level; some obvious, some not....but still connected. Are we looking at a possible chain reaction to the 8.8 mag in Chile? Or is this just a coincidence, or the affect of instant, global media coverage?

I have to say there you have it. Instant global communication is not a good thing sometimes, especially when communicating doom and gloom!

You will never see the headline "Good news. Today nothing at all happened!". It just does not have the people pulling power of "Massive Volcano Erupts in Chile - Thousands evacuated." (I hope that is not prophetic!)

In connection with the Iceland eruption for example the link I posted to "Eruptions!" gives you an insight into how the Icelanders are viewing events as several posts are written by Icelandic geophysicists/geologists. They are not panicking and indeed are mentioning some of the sillier claims in the media.

It is only my own opinion but I would say that if you want to keep informed, this is the blog for you. John Search is also very good. I gave a link for him earlier in the thread.

I suppose in some respects age has a great deal to do with the reaction to news of this type. The youngsters have not heard it all before and tend to be far more panicked by a volcano erupting than those of us who count Methuselah amongst our friends!

friends!

hahaha i needed that and your right about the media .

Full-screen
Earthquake
Country: Guatemala
State: Departamento de Escuintla
Location: Nueva Concepcion
Date: 2010-03-24 : 17:08:33
Magnitude: 4.8
Depth: 80 km

Guys, i also posted in the "Icelandic Volcano Erupts" thread, you gotta see these cams its spectacular, and later when it's dark it should be awesome, right now theres a big billowing cloud comming up from something (not the fissure itself??? not sure) check it out:

Guatemala is definitely an area for concern as regards volcanoes, and of course seismic activity related..

My response to you belongs in Quake Watch however so I have posted it there

Likely steam. There is quite a bit of it about in these eruptions. This particular link had already been posted on the thread, once exactly and once as two separate parts.

As regards seeing it when it gets dark, you may but this cam is still not looking directly at the actual eruption which is just below the sight line. You will see the glow however and so far it looks a grand night here in Ireland, so maybe in Iceland as well.

apologies if posted already, i just got really excited when i checked today and saw the weather clear and this big billowing steam cloud. Maybe it's my imagination, but there seems to be a growing mound where the lava is shooting out of to the right (not the part with all the steam on the lower left) on webcam #2, i could swear that mound grew from the other night when i saw it. Any thoughts on that?

Hey Gang, check this out, about the spreading seafloor in the Galapagos... very cool


Scientists know that the GSC is an area of extension—meaning that in between the two separating plates, lava flows are slowly creating new sea floor. They also know that the rugged terrain to the west, filled with seamounts and other topographical highs, is different than the flatter, more homogenous landscape found in the east. But they're unsure how the GSC's varied features have occurred and how they relate to each other.

Hey, no problem. I took a pic of it just now and will compare tomorrow.



It did say on the Eruptions! blog I gave the link for earlier that one part of the fissure might be becoming a cone so you are probably right.

Nice one. Thanks. Do you think they might believe in Expanding Earth when they have finished?

Found an interesting Document from the lead researchers on What happened last time Laki went.

We must remember Laki isnt likely to go now. At all.

But Katla is the issue. On the mean from all available data and history she can go Caldera Style. Sometimes not. If she does it will be the same or worse than Laki event.

She is going to go within the next 2-3 yrs, she Katla always goes after the current one that is erupting.

We are without a shadow of a doubt, now in at least a 5+% chance of a Large event when Katla goes.

Its what Iceland does.

Being the only part of Atlantic Ridge above water, with big lumps of ice on it.

Ive been watching earth, volcanos for years, studied an Bsc in environmental engineering. Ive been there and done it seen it in life etc, and all I have to say is imho this event at Katla when it happens is going to be pretty and interesting or a bloody nightmare.

This has really got my antenna's twitching as such, simple stuff, look at Katla and the current volcanos history.

Look at how many times Katla big style.

Look at what happened last time something similair happened, and if you are not insane or missing a monkey from the tree as such, well you would keep a close eye on it!

A study of the historical records of what happened in Europe When Laki went last time.

One description is not good!

The most astonishing phenomenon of 1783 was the persistent and widespread sulphuric dry fog

Cardiff University - Mortality In France Laki Event - pdf

Having said that, and its just my opinion, the last event is very interesting from a historical record of huge volcanism in earths history.

Iceland as we all know has the worlds largest Flows and one event there exuded more Lava than ever before in human history.

Lakti last time though put massive amounts of sulphur into the air, the air became sulphuric over large parts of the world!

The 1783–1784 Laki fissure-fed flood lava eruption in Iceland emitted about 122 Tg of SO2 into the atmosphere and maintained a sulphuric acid (H2SO4) aerosol veil that hung over the Northern Hemisphere for at least five months

122 Tg of SO2 !

and

Eruption columns above the vents extended to 9–13 km and released 95 Tg of SO2 into the polar jet stream, enforcing a net eastward dispersion of the plumes which reacted with atmospheric moisture to produce about 180 Tg of H2SO4 aerosols.

This is amazing here to:

Contemporary observations and model calculations indicate that the eruption columns of gas and ash above the fire fountains reached heights over 13 km above the vents during the early phases and that columns more than 10 km high were maintained for the first three months [27,28,33,38]. Consequently, the Laki eruption columns reached well into the westerly jet stream which dominates the atmospheric circulation above Iceland at the tropopause level, which is 8–9 km in summer

Good document for anyone into volcanos!


Kind Regards,

Elf

The webcam of Eyjafjallajokull glacier from Thorolfsfell is great viewing - hot steam and glowing earth can be seen in the darkness... love it

Hey puterman, is it possible to annotate that image to show where you think rise is occurring?

Taa!

reply to post by MischeviousElf


Interesting stuff indeed.

Iceland as we all know has the worlds largest Flows and one event there exuded more Lava than ever before in human history.

Glad you said human history as the Deccan and Siberia traps were much larger.

Of course Giga tons of SO2 would soon put a stop to the non-existence global warming. Good job they changed it to climate change!

Well of course I did not actually say it is rising, but, I am trying to register the daytime picture with the night-time one and I am thinking they have moved the camera slightly. I will try again in daylight.

Direct link to just the one cam

Less stressful on the computer!

On Webcam 2 - View of Eyjafjallajokull glacier from Thorolfsfell - on this site: reykjavik.mydestinationinfo.com...

Question: The main eruption is on the right - what's the activity down the slope to the left of the image - I'm watching webcam at night and there appears to be lava here, too.... is this a flow or new eruption?

EDIT: Whatever it is it's getting more active by the minute... huge ejection just then...

There's a strange glow on Hekla cam!!

Do you have a better link?

reply to post by westcoast

Nope.
Can't do better than that.
sorry

I slept most of today and missed the eruption! dam

Use Moorfnz link, it works great, but one cam offline
