Sicily's Mount Etna bursts into life once again, sending ash and lava into the air and molten rock flowing down its slopes.

Telegraph online
Thursday 12 May 2011



The magnificent scenes at Europe's largest volcano took place in the middle of the night, Etna briefly erupting between 2am and 6am local time.

Despite the brevity of the eruption, local officials were still forced to close the airport in the nearby town of Catania, with ash covering the runways.

Etna, which is almost 11,000ft high, sits 18 miles from Catania on Sicily's east coast.

As experts study the volcano, which last erupted in January, organisers of the Giro d'Italia cycle race are considering the possibility that Sunday's ninth stage between Messina and Etna may be disrupted.

I have scrambled up Mount Etna. At the foot of the cone are olive trees, houses half buried in lava, and steel pylons deformed by heat.

Here and there are fumaroles ejecting sulphur laden steam which condenses on the stones round about, coating them with bright yellow flowers of sulphur.

Much higher up it is cold, with jets of steam blowing out of vents while just a few feet away the rocks are covered by hoare frost.

Beyond the frozen zone there is heat - radiant heat from dirty, dull red lava, conducted heat from hot rocks underfoot, heat from the many jets of steam, and above all the many craters within craters, the summit crater, fiercely hot, and impossible to approach.

Volcanoes are cool to look at from the safety of my computer, but they make be glad I live in the midwest, where volcanoes are about as common as herds of zebras and tsunamis.

Thats a geyser, and it's the west, not the midwest.

Yellowstone national park is home to a supervolcano.
Old Faithful is a gyser in Yellowstone.

I've always thought it would be cool to see a fairly calm volcanic eruption or just a lava flow in person. I don't know how I'd feel seeing it. It may either be awesome, terrifying, or both. tongue

If Yellowstone ever goes up, it will make Krakatoa look small.

See "Supervolcano" for a possible future scenario, most of the effects quoted are about right.

I was watching a special regarding Yosemite.
There wouldn't be a national park with wildlife anymore.
