Volcanoes have always been a threat to humanity - although more on a local then a global scale. But scientist just recently discovered so called supervolcanos (for some good information visit this BBC section). Their eruption could devastate huge areas and influence global climate. If this thing blow Mount St. Helen will look like a tiny firecracker.

So is the end near? Nobody knows for sure. Seismic and volcanic observations are made constantly and the area is certainly active, but there are clear indicators if this thing goes off tomorrow or in a thousand years.
