Current seismic signal at Momotombo volcano (MOMN station, INETER)
Yasur (Tanna Island, Vanuatu): Strong semi-continuous ash emissions and relatively strong strombolian explosions that eject large bombs outside the crater were reported by John Seach, a regular visitor to the volcano.
The ash falls damage vegetation near the volcano and some ash fall was reported from Erromango Island located 150 km north of Yasur. John mentions large lava bombs of 4 meters in diameter.
Momotombo (Nicaragua): A small seismic swarm occurred at the volcano today. A cluster of small earthquakes of magnitudes around 1 were detected on 6 Nov under the southern flank.

Etna (Sicily, Italy): Explosions with ejection of incandescent material from the NSEC started again. Some relatively large explosions occurred at 11:51, 12:37, and 13:06 UTC. Tremor has been rising and an earthquake swarm occurred earlier at depths of 10-20 km beneath the SW flank. This could be a sign that the next paroxysm is not far away. At the moment, the tremor has decreased again a bit. ... [more]

Shiveluch (Kamchatka): An small ash plume rising to 12,000 ft (3,6 km) was detected at 11:00 UTC by VAAC Tokyo this morning (20:00 local time), suggesting another eruption (likely partial collapse from the dome). Video data show increased incandescence at that time, confirming this interpretation. ... [more]

Stromboli (Eolian Islands, Italy): Activity has remained similar since our previous visit 9 days ago: most activity is at the NW crater (towards Ginostra), where 3 vents are active and produce mild to strong strombolian explosions (to heights of up to 250 m approx) at rates of one every 5 minutes approximately, mostly from the eastern vent and sometimes from the tall hornito to the north. The eastern vent also shows weak spattering and continuous glow, suggesting a high magma level within its conduit. ... [more]
