So says Simon Winchester, who wrote a book on Krakatoa. Excerpts:

But others of the 47 known VEI-8 volcanoes are more alarmingly recent. Taupo in New Zealand erupted with mega-colossal force some 22,500 years ago. The newer of the great eruptions that helped form the mountains of today’s Yellowstone national park in Wyoming took place just 640,000 years ago, and all the current signs – from such phenomena as the rhythmic slow rising and falling of the bed of the Yellowstone river, as if some giant creature is breathing far below – suggest another eruption is coming soon. When it does, it will be an American Armageddon: all of the north and west of the continent, from Vancouver to Oklahoma City, will be rendered uninhabitable, buried under scores of feet of ash. (I mentioned this once in a talk to a group of lunching ladies in Kansas City, soothing their apparent disquiet by adding that by “soon” I was speaking in geologic time, and that meant about 250,000 years, by which time all humankind would be extinct. A woman in the front row exploded with a choleric and incredulous rage: “What?” she said. “Even Americans will be extinct?”)


And yet, of all the consequences of the truly great volcanoes of the past, the phenomenon of mass extinctions of life must surely be the most profound and world-changing of all. Between two and five major extinction events occur in the world every million years or so. We humans have not thus far been privileged to observe one of them – hardly surprisingly, since they would probably occur so slowly as to be barely noticeable. However, with painstaking care, palaeontological evidence is currently being amassed to link sudden and catastrophic changes in world climate, changes that promote such extinction crises, with the known major eruptions of the past, and with what are known as flood basalt events (such as those that have been triggered specifically in the past by eruptions of Eyjafjallajökull and her neighbouring volcano in Iceland, Katla, which is herself currently well overdue for an eruption). It is a study that opens up a fascinating speculative possibility.
For what if the kind of event that we have seen this month, and which caused us all in Europe such commercial inconvenience, is in fact not just a minor volcanic hiccup, but the beginning of an event that causes in time a mass extinction of some form of earthbound life? And further, since we know from the history books that the massive eruption of Santorini once had the power to destroy one proud part of human society, what if the extinction we might be beginning to see turns out to be what will one day surely occur, and that is the extinction of us?

It’s always something, my little Roseanne Roseannadanna. Still, this analysis of the non-pocalypse of this seismic year might put your mind at ease.
