Kilauea Volcano Produces Tephra Devils During 47th Eruption Episode
USGS scientists observed short-lived Tephra Devils forming over Kilauea’s craters during the volcano’s 47th eruptive episode last week. The phenomenon occurs when low-density tephra creates localized heat that lifts surface air into twisting columns. The next eruption is expected…
