July 4, 2024 Eruption of Stromboli

The eruptive events began at 14:10 (UTC) on 4 July and, until 5 July included lava flows, mass wasting events, pyroclastic density currents, the opening of new vents, and the generation of small tsunami waves. The lava flows, forming a lava delta on the shoreline, continued until 11 July when a paroxysmal eruption occurred at 12:08 (UTC), interrupting the effusive activity and ending the eruption. The eruption was preceded, between the afternoon of 3 July and the morning of the 4th, by Strombolian and spattering activity, small-volume collapse events affecting the N crater area, a weakly fed lava overflow and a major explosion. The July 2024 eruption of Stromboli volcano is by far the one that has most changed the morphology of the crater terrace in the last decades. (reference #14236)

On 3 July, at 16:35 UTC, intense spattering was observed from a vent located within the N crater sector, leading to a sequence of partial collapses of the N crater rim, which also remobilized material that had been erupted in the preceding days […] At 17:02 UTC, a lava flow began from the same vent, accompanied by spattering and moderate explosions […] On 4 July, at 12:11 UTC, a major explosion occurred from the N crater and, at 14:10 UTC, a new lava flow emerged at the base of the N crater area at 700ma.s.l., advancing towards Bastimento and Filo di Fuoco, located along the northeast boundary of SdF […] Between 5–6 July, 83 landslide events were observed, effusive activity fluctuated and lava emission moved further downslope […] Explosive activity from the summit craters halted at the beginning of the effusive phase. On 11 July, at 12:08 UTC, a paroxysmal eruption occurred from the N crater area, producing an ash plume 5 km high, which dispersed towards the southwest. Shortly after, a pyroclastic flow rapidly advanced along the SdF, which triggered a small-scale tsunami wave […] In the following hours, effusive activity ceased, and no further explosions were observed, except for a minor event on 12 July, at 08:28 UTC, which was followed by a small collapse event in the N crater area.
