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 30 Jun 2021 07:55.
INGV reported that there were nine episodes of lava fountaining at Etna?s Southeast Crater (SEC) during 21-27 June. The episodes were recorded shortly after midnight on 21 June, at dawn on 22 June, at dawn and sunset on 23 June, in the late morning on 24 June, at dawn and sunset on 25 June, in the afternoon on 26 June, and during the late morning of 27 June. Explosive activity was concentrated in the W part of SEC at three of the four saddle vents; some weak explosions occurred at the E vents. The episodes produced ash plumes that rose 5-10 km (16,400-32,800 ft) a.s.l. and lava flows that traveled SW and SE. Lava also began to effuse on 23 June from the vent on the SE flank of the SEC cone. INGV noted that these continuing episodes have caused the SEC cone to grow significantly, especially compared to the previous year, changing not only it?s morphology but the whole profile of Etna as well.
