What made Mount Etna’s latest eruption so rare The defining event of Monday’s eruption was the rare pyroclastic flow from the southwestern crater, not visible from a distance.

On June 2, at around 11:20 a.m. local time, a giant, superhot avalanche of ash, known as a pyroclastic flow, suddenly exploded from near Mount Etna's summit and raced down its western flank.

Mount Etna eruptions are commonly described as “Strombolian eruptions” – though as we will see, that may not apply to this event. What happened at Etna? The eruption began with an increase in pressure ...

Pyroclastic density current (PDC): A turbulent, high-density flow composed of volcanic ash, lapilli and gases that descends rapidly along a volcano’s slope following an eruption.

At least 69 people are known to have died. Most of them lived in villages on the slopes of the 3,763m-high volcano and were killed by what is known as pyroclastic flow, a searing cloud of debris.

The most recent pyroclastic flows with significant reach were recorded on Feb. 10, 2022, Oct. 23, 2021, Dec. 13, 2020, and Feb. 11, 2014, Marco Viccaro, president of Italy’s national volcanology ...
