December 4, 2022 Eruption of Stromboli

Ref #13386 states that the data from the cameras and instruments that detected phenomenon show that the tsunami was generated by the impact on the sea surface from a rather intense pyroclastic flow, similar to the one that occurred in early October (but more intense).

Ref #13390 states that on the afternoon of 4 December 2022, some volcanic events occurred involving the crater area of ​​Stromboli and the Sciara del Fuoco and which have no direct relationship with the seismic event of magnitude ML 4.6 recorded at 8:12 local time with epicenter located southwest of the island of Vulcano. At 14:10 UTC a lava overflow and a concomitant intense explosive activity started both from the northern crater area; subsequently a more intense explosion occurred from the central-southern crater area and small collapses of material were observed along the upper part of the Sciara del Fuoco. As lava overflow and explosive activity continued, one (or more) pyroclastic flow(s) was formed probably triggered by the collapse of part of the crater rim of the North sector. At 15:19 UTC there was another pyroclastic flow which lasted several minutes and produced abundant quantities of ash which temporarily blocked the view of the summit area. The fine material was dispersed by light southwesterly winds. The pyroclastic flows generated, which spread along the Sciara del Fuoco, gave rise to a large amount of ash and, once they reached the coast, generated an anomaly in the sea level which was recorded by the MEDE observation system.
