"Will a volcanic eruption destroy humanity? Scientists warn that world must begin preparing for explosive global catastrophe"?
This article says, "Scientists at the European Science Foundation estimate there is a 5-10% probability of a large explosive volcanic eruption by the end of the century". This article also says, "Experts have called upon world leaders to spend £2 billion a year to monitor volcanic activity and to increase the ability to respond".
We all know about the "for most of history" destruction/devastation of volcanic eruptions - but I do wonder about the true course of this news release - Is it actually about making ways for being more prepared and more ready around the Earth when one of these eruptions occcurs, or..........is it simply a way of supporting the spending of people's money at the tune of 2 billion pounds ($2.95 Billion) more per year??
This is an interesting read, with a fair amount of related information!

The world is woefully unprepared for a massive volcanic eruption that could kill millions of people and destroy much of modern society, a leading group of scientists have warned.
In a new report on the risks posed by natural disasters, experts at the European Science Foundation concluded that large volcanic eruptions posed the greatest risk human survival.
They calculated that there is between a five to 10 per cent probability of an explosive eruption large enough to cause huge numbers of deaths, alter the climate and poison the atmosphere occurring by the end of the century.
Such an eruption would be of a similar size to the explosion of Tambora on Sumbawa, Indonesia in 1815, which killed around 100,000 people at the time. The ash cloud thrown out from this eruption reached more than 26 miles (43km) into the atmosphere and triggered temperature changes that led to widespread famine and epidemics.
The summer following the Tambora eruption is known as 'the year without summer'.
The scientists warn, however, that rising population levels and increasing reliance on global travel could mean the impacts of a similar eruption could be far more severe.
Writing in their report Extreme Geohazards: Reducing the Disaster Risk and Increasing Resilience, the experts warn that there needs to be an international response to prepare for such a disaster and to monitor for similar events.

I wonder if a magnetic reversal would trigger the volcanos.

I keep saying Ranier is going to go and take out Seattle. Or maybe Yellowstone will go and take out the middle of the continental USA.
Shasta
I do worry about the Yellowstone super volcano. When that baby blows, a large swath of America and Canada will be unliveable. The ash ejecta will have world wide impact.
A good little site to feed your natural and man made disaster fears.

(Volcano info about 4/5ths the way down.)
But doesn't that mean the odds against the probability of volcanic eruption causing world extinction is 90 to 95%?
I posted another video on Yellowstone here somewhere...
What I found interesting is that the Magma Bubble under Yellowstone MOVES
Well to be more correct the plate OVER the bubble moves. The result is that what they first thought were separate volcanic events are really a chain of calderas as the tectonic plates move across the hot spot.
I just found a graphic that shows this with dates

This is the current hot spot

Possible as the pole flip is thought to be caused by the iron magma core flipping over. Those stresses could trigger a big one...
But it seems more likely the tectonic plate movement is responsible.
Take Japan for example
When the plates in Japan 'jumped' we got that mega quake and tsunami. Many blamed HAARP :P but below is the subduction zone that is Japan
(http://www.earthobservatory.sg/files/project/images/Tohoku2-bloc_diagramme_japan_earthquakes.jpg)
So Japan rides over top, and the seabed dives beneath back into the magma pool. It got stuck, snagged, but the pressure just built up. When it released Japan literally jumped 8 feet east while the plate beneath slid 33 meters west. It was that movement that caused the wave. It also shifted the planet by a measurable degree
Mt Fuji sits on the junction of THREE plates That is why Tokyo has DAILY quakes of around 4.0 EVERY day
(http://files.abovetopsecret.com/images/member/22edbe53c8b1.png)
Here is the IRIS record of quakes in Japan above 4.0 You will see several almost daily. Imagine living day to day with everything shaking, never knowing when the next big one will hit

So as you can see in the subduction graphic, the live volcanoes are related directly to the tectonic plate activity, As the plates move it triggers the eruptions.
Japan had several eruptions around and before the big quake
(http://www.earthobservatory.sg/files/project/images/Tohoku2-bloc_diagramme_japan_earthquakes.jpg)
Alaska has the same problem mostly along the Aleutian Island chain, which is in fact a row of active volcanoes The Aleutian Islands are a chain of 14 large volcanic islands and 55 smaller ones belonging to both the United States and Russia.
(http://www.aeic.alaska.edu/graphics/akseis.gif)
Now California is a different situation. Because as you can see below it is nt a subduction zone, rater a lateral zone (Oregon Washington and Vancover are subductiion) you would not get a Tsunami generated that could wipe out California
To create a tsunami you need the motion associated with a subduction jump, the 'sloshing effect' like pushing a bowl of water. Besides the epicenter needs to be off shore. Most of the San Andreas fault in on land along the coast so any shock wave would move outwards to the sea not inland from the sea

Interesting LOL We were talking of this region and today there are a series of quakes along it and one in Nevada California border a 5.4 just a little while ago
