Prepare for the big one, each eruption of the Eyjafjallajokull volcano in past 1000 years — 1821, 1612 and ~920 — triggered the vicious Katla.

(TimesOnline) – However, the danger is that the small volcano is just the beginning and that it will trigger the far more powerful volcano of Katla, which nestles beneath Myrdalsjökull glacier.
“That has to be on the table at the moment,” Dave McGarvie, senior lecturer at the Volcano Dynamics Group of the Open University, said. “And it is a much nastier piece of work.”
Icelanders agree. “This could trigger Katla, which is a vicious volcano that could cause both local and global damage,” Pall Einarsson, from the University of Iceland, said.
Tremors around Eyjafjallajokull were first recorded in early March, but precise prediction of volcanic eruption is difficult, even with the high-tech equipment available to Icelandic geologists.
Prediction from history …
“Eyjafjallajokull has blown three times in the past thousand years,” Dr McGarvie told The Times, “in 920AD, in 1612 and between 1821 and 1823. Each time it set off Katla.” The likelihood of Katla blowing could become clear “in a few weeks or a few months”, he said.

(BBC News) – The eruption of the Eyjafjallajoekull volcano in Iceland, and the travel chaos it has called, is only a “small rehearsal”, according to Iceland’s President Olafur Grimsson.
“The larger Katla volcano, right next to it, usually erupts every century, and the last eruption was in 1918. We have prepared our rescue services for such an event. It’s high time for European governments and airline authorities all over Europe and the world to start planning for the eventual Katla eruption.”

(BBC News) – The EU has said it will reduce a no-fly zone imposed after much of Europe’s airspace was closed because of the spread of volcanic ash from Iceland.
Transport minsters said there would be a core no-fly zone, another zone open to all flights and a third “caution” zone, allowing some flights. The move came as the UK, Germany, France and Belgium said they would begin to reopen airspace on Tuesday.

"But I will not let myself be reduced to silence."pretty damned likely to happen, imo. not that anyone should be surprised given this:
but look at the bright side, since the earth’s undeniably out of balance based on solid scientific evidence, gaia, as a self regulating system/organism, is going to resolve itself once the tipping point is reached. the result may very well be another little ice age.
we shall soon see.
Then there’s the Yellowstone Super volcano, which is long over due for another eruption (bye, bye North America).
Disruption to park activities with little expected loss of life is hardly “bye bye America”.
Besides, I’ve contracted out with the Republicans for my fear mongering.
I’m not interested in scare mongering – to my way of thinking there’s no use in being afraid of supervolcanos or asteroids, etc. We can’t do anything about them, so worrying is a waste of time and energy.
But the Yellowstone caldera supervolcano has in the past and is still entirely capable of covering a third of the US with significant amount of ash.
But don’t worry.

(Climate Progress) – Periods of exceptional climate change in Earth history are associated with a dynamic response from the solid Earth, involving enhanced levels of potentially hazardous geological and geomorphological activity. This response is expressed through the adjustment, modulation or triggering of a wide range of surface and crustal phenomena, including volcanic and seismic activity, submarine and sub-aerial landslides, tsunamis and landslide ‘splash’ waves glacial outburst and rock-dam failure floods, debris flows and gas-hydrate destabilisation.
Volcanic and seismic activity, tsunamis and glacial outbursts.Looking ahead, modelling studies and projection of current trends point towards increased risk in relation to a spectrum of geological and geomorphological hazards in a world warmed by anthropogenic climate change, while observations suggest that the ongoing rise in global average temperatures may already be eliciting a hazardous response from the geosphere.
Using the format adopted by McGuire, Liggins et al. focus on high-latitude regions, global oceans, non-volcanic mountainous regions and volcanic landscapes.
The sensitivity to climate change of gas hydrates, in both marine and continental settings, has long captured interest, in relation to its potential role in past episodes of rapid warming, such as in the Palaeocene-Eocene Thermal Maximum (PETM), and in the context of anthropogenic warming.
