Volcanologists study the volcano Etna

Modern technologies help to study the volcano Etna. Etna is the highest active volcano in Europe and one of the most active in the world. It is on the east coast of Sicily. Experts constantly keep him under close surveillance. They study the causes of recent eruptions and plot terrain changes on the map.

Another activity Etna began to manifest on February 28. A stream of lava escaped from the southeastern crater.

[Emanuela de Beni, volcanologist]:
“On the reverse side you can see a new crater and a southeastern crater. On March 15, lava flowed through its lower edge. Now we will follow the terrain where lava erupts. ”

Volcanologists will study Etna’s behavior with the help of thermal imagers. Changes will also be recorded by unmanned aerial vehicles equipped with video cameras. These studies will help to make a new 3D map of the volcano.

This year, Etna surprised specialists with an unexpected phreatic explosion. Such volcanoes did not present such surprises for a long time.

[Emanuela de Beni, volcanologist]:
“On March 16, at a height of more than two thousand meters, a phreatomagmatic eruption occurred. The reason is that much snow has fallen into the lava. ”

During the steam explosion, hot stones flew into the air. As a result, injured ten people – tourists and media workers. They were right next to the crater.

Etna is a stratovolcano. It rises to 3,300 meters above sea level. However, after eruptions, its altitude may change. For example, 150 years ago the volcano was higher by almost 22 meters.

Etna has several hundred lateral craters. Once in a few months, lava starts to flow from one to the other. The volcano has been relatively calm for the past two years. The last strong eruption occurred in 1992.
