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 23 Jun 2021 07:36.
INGV reported that there were several episodes of lava fountaining at Etna?s Southeast Crater (SEC) during 14-23 June, and additional periods of Strombolian activity and ash emissions. The lava fountaining episodes were recorded during 1332-1450 on 16 June, 2220 on 18 June to 0210 on 19 June, 2040-2215 on 19 June, 1131 on 20 June to 0214 on 21 June, overnight during 21-22 June, and in the early hours of 22 and 23 June. Each episode began with Strombolian activity which was followed by lava fountaining and crater overflows sending lava down the flanks. Ash plumes that rose as high as 4.7 km above the summit and sometimes caused ashfall in areas downwind. Lava flows on 16 June descended the SW and SE flanks, and those produced on 21 June traveled about 1 km SW, towards Monte Frumento Supino, and stopped at 2,900 m elevation. The lava fountains on 21 June were notably tall.
