Volcanic Lightning Could Aid Hazard Response During Eruptions
Lightning and ash plume dynamics reflected eruption behavior and signaled the onset of fast-moving rock and gas flows during the 2015 eruption of Chile's Calbuco volcano.

Sound Waves Help Scientists Track Volcanic Eruptions
When sound waves hit the ground, they shake seismometers like earthquake waves. Scientists can now use these sound-induced seismic waves to investigate volcanic activity.
