Etna's youngest and most active crater has risen to a record 3,357 meters above sea level, reported
“Thanks to the analysis and processing of satelliteFrom the images, we saw that the southeastern crater is now much higher than its “big brother”, the northeastern crater, which for 40 years was the undisputed peak of Etna,” says the INGV press release.

This sudden growth spurt is a resultabout 50 eruptions in the southeastern crater since February 16, 2021, which led to a “noticeable change in the shape of the volcano,” INGV said. Scientists discovered the explosive growth when analyzing images taken by the Pléiades satellites taken on July 13 and 25. The data has an error of about 3 m.
After the eruption of the northeast crater in 1980and in 1981 it reached a maximum height of 3350 m. But this height decreased over the years, when the edges of the crater collapsed. As of the summer of 2018, the northeastern crater was 3326 m high.
It is believed that Mount Etna originated as an underwater volcano that slowly rose above sea level, erupting over and over again, gradually increasing in height due to solidified lava.
