Lab experiments of fluidized granular flows entering the water shed light on the dynamics of tsunami generation by fast-moving, pyroclastic density currents at volcanic islands or coastal volcanoes.Read More »Geochemistry, Mineralogy, Volcanology
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.Read More »Geochemistry, Mineralogy, Volcanology
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.Read More »Natural Hazards
Granular flows are important in geophysics to the pyroclastic flow, debris flow, and avalanches. Understanding their complex and rich physics is therefore important in simulating their dynamics.Read More »Geochemistry, Mineralogy, Volcanology
The first results are published from experiments that aim to illuminate the physics of lava-water interactions, which can sometimes make eruptions more dangerousRead More »Geochemistry, Mineralogy, Volcanology
An artist’s impulse to recreate natural landscapes leads to fiery scientific explorations that elucidate the behavior of erupting lava and the solid shapes it becomes.Read More »Natural Hazards
Artificial volcanic plumes, fired from cannons loaded with ash plucked from the slopes of Iceland, may help researchers better monitor disruptive eruptions.Read More »
