In case your kids have been asking, how dangerous are the Pacific Northwest's volcanos?
These volcanoes don’t typically explode without warning. They have a baseline of earthquake, ground deformation and gas activity, even when they aren’t erupting. The pattern of that activity can be a clue to what will happen next.
Maybe tell them it's the earthquakes they should be freaked out about.
