Lessons from a Post-Eruption Landscape
Four decades of research into biophysical responses to the 1980 eruption of Mount St. Helens have vastly improved our understanding of how landscapes react to cataclysmic disturbances.

Kīlauea Eruption Abruptly Slows Down
Volcanologists say it’s too soon to know whether the sudden drop in activity signals the end of the eruption or just a pause.

Huge Spike in Quakes Badly Damages Kīlauea Observatory
Meanwhile, some scientists say that the 35-year eruption from the Pu‘u Ō‘ō vent has ended and that the flows since 3 May are a new eruption. Others take issue with this view.

Harnessing Remote Infrasound to Study Volcanic Eruptions
Data from the 2015 eruption of Chile’s Calbuco volcano suggest the international network built to monitor nuclear explosions may also be used to detect and characterize volcanic activity.

Satellite Observations Could Help Forecast an Eruption’s End
Researchers studying past volcanic activity found they could retrospectively predict when outflows of molten rock would cease for about 40% of effusive eruptions, the kind that produces flowing lava.
