PUERTO MONTT, Chile (Reuters) - A towering plume of ash from an erupting volcano in Chile's remote Patagonia could collapse back down to devastate the surrounding area, a leading expert warned on Friday.
Luis Lara, a geologist and volcano expert with the government's geology and mining agency Sernageomin, says his models show the vast column of ash, which has soared 7.5 miles
into the air, at a critical stage.
A sudden collapse would shroud vast areas with hot gas, ash and molten rock, killing anything in its way.
Authorities have evacuated thousands of people from the immediate vicinity of Chaiten volcano, 760 miles south of the capital Santiago, and are forcibly removing people within a 30 mile radius.
Chaiten began erupting eight days ago for the first time in thousands of years.
"We are at a critical point of this phase given the characteristics (of the eruption) have remained the same for several days," Lara said.
"The volcano is now at its limit and one possibility is that the column could collapse quickly, generating flows of pyroclastic material down its ravines," he added. "But there are also other scenarios, such as the energy of the eruption being released more gradually."
In a worst case scenario, the flows of ash and fiery material could reach the fjord Chaiten sits on, sending a series of small waves fanning out toward settlements up to 125 miles away across the water.
Lara says the volcano could rumble on for years. He suggested the town of Chaiten, 6 miles from the volcano and now deserted, should be moved.
"In an ideal world, I would move the town somewhere else more protected," Lara said. He would not risk living there.
The cloud has also caked towns on the Argentine side of the border with ash. Satellite images show a white stripe smeared across the continent.
However ash that had drifted as far as Buenos Aires dissipated on Friday, and some airlines which canceled flights overnight resumed service.
Chile is home to 2,000 volcanoes, 500 of which experts say are potentially active. Around 60 have erupted over the past 450 years.

Is it OK to speculate that this might contribute to climate change now?
Not to be outdone, East Texas has its own collapsed dome but it isn't emitting hot gas, ash and molten rock yet.
Has AlGore made it to the summit yet?
IT’S STILL BLOWING????
Spielberg is jealous of that light show.
Someone should send him.
Is it the end of the world, as we know it?
Wow! Great Photos!
Here goes global cooling!
Every now and then a big volcano goes off and it cools the earth slightly for a couple of years. Mother nature knows what she's doing!
Not hard to imagine why the ancients thought there were gods inside that mountain.
If this keeps up, it could end the drought in Australia.
Mt. Pinatubo belched more bad stuff into the air than all of mankind has for the past 150 years. After this eruption Id have to say WE ARE ALL DOOMED!. Bush’s fault of course.
Do you mean global warming will be coming....I’m hoping and praying....please, oh please, give us some warmth...we’re tired of this da*n cold!!!
WOW!
That is an awesome sight. I wonder if the UN or EPA will cite the volcano for air pollution?
bd....would you mind using your ping list? These pictures are AWESOME!!
Is it the end of the world, as we know it?
I hope not, I got a mortgage to pay off... on second thought.
The Earth is a living entity with volcanic zits, some which lie dormant for long periods of time, this year was its turn to plume up after 9300plus years since its last eruption..
The Martians are obviously using the cover of this eruption to beam into their Tri-Pod Machines.
Are those lightning shots for real? They look AWESOME!!.......
Bump for those pix!
Actually it’s a continuation of the world as we know it.
“Are those lightning shots for real? They look AWESOME!!.......”
According to the site I got those from, the hot air/ash ionizes the air causing lightning storms. Pretty cool.
AMAZING PHOTOS
Does anyone here know how to take night time photos like that?
I can’t even take a decent picture of a moonscape over the valley in my front yard
How about we just move the volcano about 10 miles south east of D.C. We could then evacuate the place except for congress. I bet they would move fast on some bills Polise and Reed have been stalling on so they could call a recess!
These are long-exposure photos.
Looks like the shutter was open for atleast 30+ seconds, for the camera to register that many flashes of individual lightning.
You have to leave the shutter open.
I would really like to get high res versions of the first two pics for my wallpaper changer.
Amazing photos!
Those are some cool pictures. I am not making light of the disaster, but wow!
Depending on the lens set that your camera has, and the manual modes that it supports, you can try the ‘shutter priority mode,’ use a tripod and a remote shutter release, or the timer function in lieu of it, and toy around with the exposure timings, to get a good, noise-free shot.
Of course, I’m assuming that you use a digital camera, at minimum one of the DSLR-ish prosumer models.
My chilli’s good, but it ain’t THAT good!.............
I don't know, but I feel fine.
“You have to leave the shutter open.”
And the camera on the tripod.
And run like hell!

Since volcanic ash naturally releases particulates that block sunlight, this could solve all our global warming problems - at no expense to US taxpayers or the economy.
Assuming, of course, it doesn’t start an ice age.
oops sorry about the double post......
Of course not. But we'll all be told not to have wood burning fireplaces and summer barbecues to cut down on global warming.
Very funny!
Lets see? billions of tons of ash spewed into the atmosphere. Sounds like GLOBAL COOLING TO ME. The question is will Al Gore come out of hiding and proclaims a global cooling trend?
“What’s with the one green bolt in the two lightning photos, I wonder? “
Scientifically, or metaphorically?
Ash doesn’t cause cooling. Sulfur Dioxide does.
It’s not emitting much sulfur dioxide as volcanoes go.
And it’s actually not THAT enormous of an eruption, which I’m sure people will find hard to believe. It’s no Pinatubo.
Also the further away from the equator the less climate effect a volcano has.
I wouldn’t anticipate any climate effects from this at all.
