Gamblers Take Odds on the Next Violent Volcanic Eruption

Mount Ranier It looks serene, but 11-to-1 says not for long.

Seismologists and geologists would love to know which volcano is going to erupt next. Now, so do bookies, odds-fixers and those with a taste for games of chance. Paddy Power, Ireland's largest bookmaker, is taking bets on which volcano around the world will next blow its top to the tune of a VEI-3 eruption. Following the recent eruption of Philippine's Mount Mayon, apparently Paddy Power was flooded with requests by -- and we're quoting here -- "punters around the globe" who wished to wager on nature's next super-destructive geo-seismic event. Apologies up front to Japan; it seems the odds are stacked against you.

A VEI-3 eruption (that's Volcanic Explosivity Index, something like a Richter Scale for volcanic activity, but with better adjectives) is considered "severe" but not uncommon, the kind of event that shook Italy's Mount Etna in 2002-2003 (by comparison, Mount St. Helens' 1980 eruption was a level 5, or "paroxysmal" according to the scale). Descriptors on the VEI scale run the gamut from VEI-0 "non-explosive" and VEI-1 "gentle", to the VEI-4 "cataclysmic" variety and on up to the strongest VEI-8 "mega-colossal" eruptions (naturally preceded by level 7 "super-colossal" and level 6, which is merely "colossal").

That is to say a little rumbling from Italy's Mount Etna may not indicate that you should bet the farm on its 28-to-1 odds, but if you notice Mauna Loa starting to belch cinder, perhaps it's time to move on that better 9-to-1 book before the line changes. Japan's Mount Unzen is deemed most likely to blow -- between '91 and '94 it generated more than 10,000 pyroclastic flows, good for odds-making but bad for the 2,000 families that lost their homes.
