How rivers of hot ash and gas move when a supervolcano erupts

A new study in Nature Communications sheds light on what happens when a supervolcano erupts, providing insight on how rivers of hot ash and gas called pyroclastic flows manage to travel huge distances of over 100 miles during supereruptions. The research combines recent laboratory experiments with field data from the 1980s — some of it captured in colorful Kodachrome slides — to provide a somewhat counterintuitive finding. —> Read More
