An explosion has occurred at the Bocca Nuova crater of Etna this October 10 at 1:26 p.m. UTC / 3:26 p.m. local.

This is the first activity observed at the Bocca Nuova after its filling by the products issued during the eruptions of the Voragine in December 2015 and May 2016.

The explosion was recorded by thermal cameras of Montagnola (EMOT) and Bronte (EBT); she was accompanied by a small ash plume amount to a few hundred meters above the summit.

This explosion produced a seismic signal, which is then repeated more weakly, with a stronger earthquake at 15:16 UTC.

The cloud cover prevented any visual observation or thermal camera.

In Turrialba, tremor of moderate magnitude was recorded during the night of 9 to 10 October and in the morning of 10, with a passive emission of ash, whose height did not exceed 300 meters above the crater .

These issues continued during the day, continuously, but with a variable volume.

The winds have scattered the ashes to the northeast in the morning, before  moving southwest in the afternoon.
