1 Laguna del Maule (Chile)
Currently inflating at the astonishing rate of 25cm a year, above a growing body of magma just 5km beneath the surface.

2 Uturuncu (Bolivia)
A 70km-wide bulge that has been growing since the early 1990s could culminate in a gigantic eruption.

3 Alban Hills (Italy)
Just 20km south-east of Rome, this huge volcano has started to become restless following more than 30,000 quiet years.

4 Campi Flegrei (Italy)
The archetypal “restless volcano” on the edge of Naples has not erupted since 1538, but has shown worrying signs, on and off, since the 1970s.

5 Yellowstone (Wyoming, US)
No eruption for around 70,000 years, but congenitally restless.

6 Mount Fuji (Japan)
Quiet since 1707, but scientists recently warned that the volcano was in a “critical state” with a “high potential for eruption”.

7 Mammoth Mountain (California, USA)
In September 2014, up to 300 small earthquakes a day shook this part of the Long Valley supervolcano.

8 Askja (Iceland)
Swarms of small earthquakes and a crater-lake that was ice-free last winter hint at magma on the move for the first time since a major blast in 1875.

9 Mount Paektu (North Korea-China)
In 940 it hosted one of the greatest eruptions of the past 10,000 years; signs of unrest are again evident.

10 Cumbre Vieja (La Palma, Canaries)
A collapse of the unstable west flank could spawn a North Atlantic mega-tsunami.

"Hazarding a guess about when and where the next Tambora will explode is far from an exact science. Eruptions on such a scale seem to happen, on average, a few times every millennium and one estimate holds that there is a 1 in 10 chance of a comparable event in the next 50 years. The Earth does not, however, operate to a timetable so such an eruption is equally likely to occur in any single year."

a little doom porn for your weekend...

I'm glad I'm in Florida, inland and high enough not to have to worry about a tsunami. At least with the hurricanes you can see them coming.

There is a 30 percent chance of another Tambora-size eruption striking this century, according to a new global volcanic hazard report prepared for the United Nations. An international team of experts, known as the Global Volcano Model Network, culled reports of the death and destruction wrought by volcanoes and ranked the countries most likely to face such future disasters. The report, called "Global Volcanic Hazards and Risk," will be published in May by Cambridge University Press.
Indonesia remains the country most at risk of another deadly volcanic eruption, according to the new report.

far away, but a real big boom would have global consequences

We be livin' in the shadow of Mt. Ranier, just down the road from Mt. St. Helens....
Yes, I'd be more concerned about Mt. Rainer than many of the other volcanoes on the list. Mainly because people have built too close, and in the lahar routes that stretch all the way down to the ocean. If Rainer gets active huge numbers of people will be in danger. :eek:

We look at Mt. Rainier daily and wonder when not if. We are due for a major earthquake and a major lahar. I just hope not at the same time.
When you live in the Ring of Fire, you can always find something to worry about. However we don't have to worry about hurricanes, tornados, etc.
I really don't think there is any place in the world that is perfectly safe (natural calamities) so I just let nature take her course.
Have a blessed day.

more magma stuff found under Yellowstone

http://www.reuters.com/article/2015/04/23/us-science-yellowstone-idUSKBN0NE28420150423


""Deep beneath Yellowstone National Park, one of the world's most dynamic volcanic systems, lies an enormous, previously unknown reservoir of hot, partly molten rock big enough to fill up the Grand Canyon 11 times, scientists say.

Researchers on Thursday said they used a technique called seismic tomography to a produce for the first time a complete picture of the volcanic "plumbing system" at Yellowstone, from the Earth's mantle up to the surface.""
like it wasn't bad enough...

There are already mud slide maps published for Puget Sound that plot out the expected destruction. Whole cities will be washed into the Sound.

And those are just the ones on land! Scientists recently discovered a huge underwater volcano after tons of pumice wash up on Australian beaches.

"Seventy-five per cent of Earth's volcanos are actually on the sea floor and they provide heat and chemicals to the ocean that basically influence the bio-geo chemical cycles of the Earth.

"These eruptions are very frequent.

goodness yes. Lord only knows what's going on down there.
wonder if there's enough submarine volcanic to raise the ocean temp (global warming?)...

Good point. If man's activities can supposedly do it, then I'd say it's even LESS of a stretch to say that millions of years of underwater volcanoes, spewing countless million cubic meters of molten lava and scalding hot gasses into the ocean could have a discernable effect.
But still, I'm quite confident that all this can be easily countered by all of us driving Priuses and paying our carbon taxes !!!! :D:

i believe that a tsunami from cumbre vieja would cross the state. the highest point in florida is only somewhere around 380ft and most of it is around 80ft. the wave would be upwards of 150ft. so i would check a topo map to make sure that you not only survive such a tsunami but also have a way out if disease and pollution get to be a problem in the aftermath.
