But if we can believe the genetic studies, did not the Supereruption 70,000 years ago (Toba) very nearly wipe us out? Granted, it did not, and may have led to innovative survival techniques (there appears to be evidence, based on louse DNA, that textiles as we know them came into being shortly after the eruption, probably to provide warmth during the period of cold that followed).

I agree, though, that geological studies that give us decades of warning are much more useful than running about madly crying that, "the Supervolcano's about to erupt!"
