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 31 Mar 2021 11:27.
INGV reported continuing episodes of lava fountaining at Etna?s Southeast Crater (SEC) during the week of 22-28 March, though weather conditions often prevented visual observations. Weak Strombolian activity at SEC began at 2005 on 23 March and turned into lava fountaining at 0330 on 24 March. A lava flow from the SEC was observed at 0335 which split in two, one branch traveling toward the Valle del Bove and the other to the SE; the lava was followed by a pyroclastic flow at 0336 that traveled toward the Valle del Bove. The lava fountain produced an ash cloud that rose to 6-7 km (20,000-23,000 ft) a.s.l. and extended SSE, resulting in ashfall on the S slope and in Catania (29 km SSE). Lava fountaining gradually decreased at 0700, and by 0945 it had stopped. The lava flows continued to advance. Activity in Northeast (NEC), Bocca Nuova (BN), and Voragine (VOR) was characterized by variable intra-crater Strombolian activity, accompanied by sporadic and weak ash emissions that quickly dispersed.
On 24 March explosions at SEC continued after the lava fountaining had stopped, producing an ash plume that rose 4.5 km (15,000 ft) a.s.l. and drifted SE. At night, ashfall was reported in Milia and Trecastagni (16 km SE). Explosions stopped by 1347 that day. By 25 March the two active lava flows had ceased and began to cool. Weak Strombolian activity at SEC on 30 March resumed around 2030; intra-crater explosions continued in the NEC, BN, and VOR, the latter of which produced discontinuous ash emissions that rapidly dispersed in the summit area.
