On any given day, there are typically about 20 volcanoes erupting world-wide. Usually no one pays
much mind. That changes dramatically when a volcano poses a real threat to lots of lives due to
pyroclastic flows. As we have seen, dumping a lot of ash into the atmosphere at the wrong place
can be very disruptive. Then there are super-volcanoes like Toba that can change the planet and
everything on it - notably our species. It is a popular belief in Iceland that various volcanoes cause
other volcanoes to erupt.
