Updates on volcanic activity (Smithsonian)
The Smithsonian/USGS Weekly Volcanic Activity Report provides information about global volcanism on a weekly basis. Latest Etna report has been published on 10 Feb 2021 07:28.
INGV reported that Strombolian activity from all four of Etna?s summit craters, the Southeast Crater (SEC), the Northeast Crater (NEC), Bocca Nuova (BN), and Voragine (VOR), was visible during 1-7 February; the last time that had occurred was during 1998-1999. The strongest and almost continuous Strombolian explosions at SEC originated from two vents in the E part of the top of the cone. Tephra accumulated near the top of the cone and rolled down the flanks. Minor ash emissions rapidly dispersed. Less-intense Strombolian activity occurred at the S vent. Intra-crater Strombolian activity at NEC sometimes produced nighttime crater incandescence. Strombolian activity at BN sometimes ejected coarse material beyond the crater rim, and rare ash emissions that had diffuse ash content. On 5 February scientists observed explosions from three vents at the bottom of the crater that had formed cinder cones. Nearby was another cone that occasionally produced dense emissions that rapidly dispersed. Strombolian activity at VOR ejected material that sometimes rose above the crater rim and generated diffuse ash emissions. On 5 February lava flowed into BN, overlapping flows from the previous week.
