We’re all familiar with the dangers from hurricanes, earthquakes, and tsunamis. But what about volcanoes? Well according to a recent report from the U.S. Geological Survey, threats from America’s 169 volcanoes which have either erupted or recently quieted could be significant, with 18 of these fiery mountains posing a very high danger to people and aviation. The research notes that, very disturbingly, monitoring of volcanic activity is grossly inadequate, with only about a dozen peaks receiving the attention they deserve. The scientists are urging the creation of a comprehensive early-warning system for volcanic unrest, which might be well advised before something, somewhere blows its top!
