The ongoing highly elevated activity at the volcano resulted in a spectacular, billowing pyroclastic flow tumbling down the Sciara del Fuoco this morning at about 07:20 local time.
INGV volcanologists concluded that a part of the rim of the crater (likely North)had collapsed that culminated in hot rock falls traveling beyond the coastline above water for about several dozens-to-hundred meters. Ash plumes separating from the flow (so-called phoenix clouds) rose several hundred meters above the volcano. The pyroclastic flow triggered 2 cm high sea waves registered by the tsunami warning system.
The event has been associated with a new lava flow as well, emerging from a vent in the summit area and simultaneously descending with the pyroclastic density current and pouring into the sea.
A period of high amplitude tremor accompanied the crater rim collapse, currently continues at medium-high values.

After days/weeks of increased activity (which included a major explosion and 2 effusive events) at #stromboli, this morning a partial collapse of the crater rim generated a flow and initiated a lava effusion. Ondametric gauges recorded a 2-cm tsunami@LGS_UNIFI pic.twitter.com/P2vPmmX4ne

Dopo il flusso piroclastico principale di questa mattina, lungo la Sciara del Fuoco dello #Stromboli stanno continuando a formarsi alcuni flussi minori che interessano tutto il pendio settentrionale del vulcano, allo stesso tempo la colata di lava continua a riversarsi in mare. pic.twitter.com/35RkkW4CEM
