Thera?
Forget Thera. Yellowstone PArk is actually a Caldera. It is literally rising due to a build up of Magma in its magma chamber. Based on the gelogic recorfd it is due to blow, covering the continent in ash.

I see you also saw the Discover Channel show on mega-tsunami.

Yeah, there is also Ebino Caldera in kyushu, japan, which is the biggest, I believe (could be wrong)....but my post above was just referring to the geological present on earth, i.e. the last few thousand years; i.e. just plain old volcanos cutting off light to earth with ash versus the end -all-life-on-earth super-calderas...I would think one of those going off would be similar to the alvarez meteor impact in yucatan with regards to its effects on the biosphere.

isn't the area of northern ireland known as the giants causeway in atrium (a spectacular bunch of basalt columns) one edge of a caldera stretching between isle of man, scotland, and ireland also?

AS a New Yorker, it is reassuring to know that I can die of manything besides an Islamofascist with a nuke.
Please excuse me while I take out life insurance.
