Volcanic activity worldwide 7 Nov 2013: Etna

Explsion from Etna's New SE crater in the afternoon
Etna (Sicily, Italy): Intermittent strombolian explosions continue to occur every 10-15 minutes from the New SE crater. Tremor levels are fluctuating with no clear tendency (yet).
Current tremor amplitude (ECPNZ station, INGV Catania)
Strombolian explosions have continued throughout the night and and this morning with little variations. Tremor has been rising overall, then dropped and now risen again. Judging from this, the volcano seems still "undecided" whether and when to head towards the expected 15th New SE crater paroxysm.
The following time-lapse shows the activity over the past 20 hours:

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]
