A rumbling volcano on Indonesia's Sumatra island spewed clouds of smoke and ash high into the air Friday, the latest in a series of violent eruptions.
Farmers continue tending to their crops and people in local towns put on masks to go shopping as ash rains down from the sky.
A little while ago there was a short interview published with Professor in geophysics, Páll Einarsson. In the interview it seemed like he was stating that Bárdarbunga, Grimsvötn, Hekla and Katla all were preparing to erupt shortly.
First of all let me state that I deeply respect Páll as a geophysicist, problem is just that he is probably the most misquoted and misinterpreted scientist on the planet. The problem is that he is talking about geological timeframes and he uses words like “shortly” and “soon” in that context and then the journalist happily thinks he is talking about the next few weeks…
And I won't be around when it does.
About one-third of the active volcanoes in the U.S. have erupted—some of them repeatedly—within the past two centuries.
...“but most of the really dangerous volcanoes haven’t erupted in modern instrumental times.”
Almost half of the active volcanoes in the country don’t have adequate seismometers
Hawaii’s Kilauea, Washington’s Mt. St. Helens, and Wyoming’s Yellowstone all have extensive monitoring. But many volcanoes in the Cascades have only a couple of far-field sensors, several geologists told me. The Pacific Northwest, which includes high-population areas in close proximity to active volcanoes, is of particular concern for public safety.
Flight CHAOS looms for Brits as Iceland volcanoes 'ready to BLOW' into ash cloud hell
But volcanologist Rymer, who says all four volcanoes are now "waking up", warns: “The increased seismicity (earthquakes) is a sign of an impending eruption and so we are on our guard.
“There certainly will be another eruption at one of these volcanoes, but at the moment we do not have an indication that this is imminent.
