Toba event practically wiped out all forms of 'modern' human life when it happend, plunged global temps by 8c overnight or something daft. Covered it in paleoecology last term.james@alienware wrote:

That whole lake is a crater. Wow.

There is more to read at souce link but not looking good if both volcanoes erupt within the same time span.Monday, February 02, 2009: Mount Redoubt volcano in Alaska could erupt within days to weeks, say scientists at the U.S. Geological Survey, amazing the rest of us with their certainty.
Here's what makes them so sure: Magma rising toward the surface from beneath a volcano like Redoubt can cause earthquakes and other seismic rumblings. And seismic activity at Redoubt, which is 106 miles (170 km) southwest of Anchorage, has increased recently.
"If you're going to bring magma to the surface you've got to break rock, and every time rocks break at the subsurface beneath a volcano, that's an earthquake," said volcanologist Charles Mandeville of the American Museum of Natural History in New York. "They're recording a whole bunch of earthquakes almost continuously right now," he said, referring to scientists at the Alaska Volcano Observatory in Anchorage.

No sure if any one mentioned it but here is a one-two punch for you. Alaska has an active volcano that is almost ready to erupt.

Mushroom clouds are not good. Though more concern of how much ash it throws up in the atmosphere; it probably will have an impact on North America.FatherTed wrote:

That's what it looked like last time it blew
I don't really think thats a world ender though
It's the scale though. Although it looks massive, all it really might do is travel quite far and cause some atmospheric pollution. Oh, and piss off planes. I could be very wrong (i haven't done seismology yet), but i don't think this Volcano is of the size to cause any noticeable global (hell, even national) atmospheric effect.loubot wrote:
