From Kilauea to Fuego: three things you should know about volcano risk

Important points about volcanoes: location matters, explosiveness can be predicted to an extent, and fast-moving flows of volcanic materials (known as pyroclastic flows) are deadly.

More bad news for dinosaurs: Chicxulub meteorite impact triggered global volcanic eruptions on the ocean floor

Research suggests a new threat to life on Earth from the meteorite's crash: Via seismic waves, the impact triggered massive undersea eruptions, as big as any ever seen in our planet's history.
