Sinabung, Vesuvius, Bardarbunga: the risks


Why in Europe and all over the word, we have to prepare us to face a volcanic crisis?

Activity has picked up considerably at the volcano during the past days. Several pyroclastic flows (dangerous hot avalanches of fragmented lava and hot gasses) traveled down the SE (and some on the NE) flanks of the volcano, threatening again the closest inhabited areas to the S of Sinabung.

But the greatest risk for Europe comes form Vesuvius.

Vesuvius is one of the most dangerous volcanoes in the world — but scientists and the civil authorities can’t agree on how to prepare for a future eruption. “There would be no modern precedent for an evacuation of this magnitude,” says Giuseppe Mastrolorenzo at the Vesuvius Volcano Observatory in Naples. “This is why Vesuvius is the most dangerous volcano in the world.”

Professor Magnús Tumi Guðmundsson, professor of geophysics at the University of Iceland´s Institute of Earth Sciences and the foremost Icelandic expert on subglacial eruptions outlines the three following scenarios:

1) The eruption at Holuhraun stops and with it the depletion of the magma reservoir of the Bardarbunga system also stops.
2) The eruption at Holuhraun continues as does the depletion with an accompanying subsidence at the Bardarbunga caldera. (As this goes on, the risk of possibility #3 increases, our note).
3) The deflation reaches a critical point where part of the roof of the Bardarbunga caldera collapses which allows water, liquid or in the form of ice, to interact directly with the magmatic main body. (This will lead to a series of very violent explosions which will only stop when either the body of water/ice or the body of magma are exhausted, our note).

Poco dopo la mezzanotte di venerdì 29/08/2014 è iniziata una piccola eruzione con emissione di lava e fumo da fratture in prossimità del vulcano.

Il traffico aereo al momento non ha subito ritardi, anche se l’allarme è tornato al livello rosso. Nei prossimi giorni ci si può aspettare un peggioramento a causa dei venti che potrebbero spingere la nube di ceneri verso sud, sull’oceano atlantico.

A livello locale il maggior rischio è costituito dai ghiacci che ricoprono il vulcano che potrebbero sciogliersi a causa dell’eruzione provocando allagamenti.

Nel caso si verificasse lo scenario N° 3. Il problema è serio anche per quanto riguarda il clima, se la quantità di ceneri immesse in atmosfera fosse davvero abbondante, potrebbe influenzare il clima di tutta l’Europa provocando una piccola era glaciale nei prossimi anni. I danni economici, soprattutto per l’agricoltura sarebbero enormi.

Watts Up With That?

Eric Worrall writes: The British and Icelandic MET offices are expressing concern about the possible effect on the climate, of a potentially enormous volcanic eruption in Iceland.

Iceland-Bardarbunga-VolcanoAccording to The Express, a UK daily newspaper;

“BRITAIN could freeze in YEARS of super-cold winters and miserable summers if the  erupts, experts have warned.

Britain could face a freezing winter if the Icelandic volcano erupts Britain could face a freezing winter if the Icelandic volcano erupts.
Depending on the force of the explosion, minute particles thrust beyond the earth’s atmosphere can trigger DECADES of chaotic weather patterns.

The first effect could be a bitterly cold winter to arrive in weeks with thermometers plunging into minus figures and not rising long before next summer.

The Icelandic Met Office has this week warned of “strong indications of ongoing magma movement” around the volcano prompting them to raise the aviation warning to orange, the…
