Eruption updates & news from Stromboli:
Stromboli (Aeolian Islands, Italy): new small lava flow from the summit crater

The new lava flow on the evening of 25.12.
Seismic signal this morning
The activity at Stromboli has lately increased, as our colleague Marc Szlegat observed over the holidays. Since 23 December small lava overflows occurred from the eastern crater area and produced lava flows with varying length on the upper part of the Sciara del Fuoco.

Yesterday afternoon and evening, it looked as if the lava flow had increased and extended on a good portion of the Sciara where lava blocks detaching from the flow rolling down created a dense incandescent stream.
It is still unclear whether the flows come from a new vent at the eastern crater terrace or whether they are overflows of lava from an existing vent.
The seismicity is increased and in addition to the tremor, explosion and rockfall signals are elevated as well.
Such lava (over-)flows from the crater are usually relatively short-lived, but come often in phases.

On 22 November, Stromboli emitted a 3 KM high steam plume. The INGV stated that on 22 November, at 13:17 (GMT) a large seismic signal associated with an explosion occurred. The explosion was around 7 times higher than an average explosion. The explosion was followed by 10 minutes of high seismicity. [more]

The current storm over the Tyrrhenian Sea is probably causing the elevated amplitudes visible in the seismic recordings. [more]
