A theoretical model coupled to lab experiments on turbulent jets with reversing buoyancy sheds new light on the role of wind in controlling the dynamics of volcanic eruptive columns.
In lab experiments and models, researchers uncover how ash can affect the standing shock waves of erupting volcanoes. Their findings may lead to new predictions of volcanic ash hazards.
Little seismic unrest preceded the 2014 eruption of a stratovolcano in Indonesia, which suggests that the eruption was kick-started internally by volatile-triggered overpressure.

Artificial volcanic plumes, fired from cannons loaded with ash plucked from the slopes of Iceland, may help researchers better monitor disruptive eruptions.
