Invisible electrical bursts could be cue for explosive, ash-heavy volcanic eruptions, says new research


July 1, 2021

A new study has said that monitoring lightning and invisible electrical bursts, known as “vent discharges,” at volcanoes could help predict imminent and explosive ash-rich eruptions which may be dangerous for people and planes.

In the research, published recently in the journal Geophysical Research Letters, a team of scientists led by Cassandra Smith, a volcanologist at the Alaska Volcano Observatory in Anchorage, presented their findings after monitoring 97 different volcanic explosions in order to learn more about the connection between electrical activity and volcanic activity. The field work took place at Japan’s Sakurajima volcano back in 2015.
