HELENS · CASE STUDYThe Morning the Mountain UnzippedOn May 18, 1980, an earthquake set a weakened north flank in motion.

The disaster exposed a blind spot in warning systems built around earthquakes.09 / MOUNT ETNA · CASE STUDYEtna’s Four Nights of FireA burst of activity in February 2021 turned the Southeast Crater into a lava fountain—and sent ash and lapilli across parts of eastern Sicily.10 / MOUNT SEMERU · CASE STUDYSemeru’s Deadly River of Ash and DebrisOn December 4, 2021, hot volcanic flows and rain-remobilized sediment transformed valleys below Semeru.
