Scientists witnessed lava flow from Europe’s highest volcano, Mount Etna. Volcanologists are using advanced technology to study the eruption and monitor the volcano. They use thermal imaging, lava flow mapping, and GPS measurement, along with drones to captures images. All of this technology is being used to better understand the volcano.
After relative dormancy for the past two years, Etna showed increased activity a month ago. Explosions and minor eruptions have been the result of hot lava meeting with cold snow and ice while flowing down of the volcano. Once the lava melts the snow, it becomes water, and then trapped steam bursts through, spewing debris.
Etna’s last major eruption was in 1992.
