Actually, the Mammoth Lakes area is the site of an ancient volcano with a quite large caldera (think of it as an "almost supervolcano"). If we get an eruption of this volcano again we may be talking the possibility of more volcanic ash spewed into the atmosphere than the Mt. Tambora eruption back in 1815 (Tambora spewed out 15 cubic miles of ash), but it won't be anywhere close to the potential amount of ash from an eruption of the supervolcano in Yellowstone National Park; scientists have estimated that the last Yellowstone eruption spewed some 50 cubic miles of volcanic ash into the atmosphere.

Thank goodness this isn't the Mammoth Lakes area, although when the 5.5 hit earlier today that was my first thought.

I hope me and mine are long gone when Yellowstone erupts.
