Stromboli (Eolian Islands, Italy): Activity remains elevated. Lava continues to overspill from the lips of the NE crater, showing that the magma column stands high inside the conduit. Frequent strombolian explosions are reaching heights of 2-300 m and the tremor signal is strong again today.
Etna (Sicily, Italy): The eruption is still intensifying. Strombolian explosions are about to merge into lava fountains.
...12 Apr:
The eruption continued all night with strong strombolian explosions and the slow effusion of one or several lava flows from the eruptive fissure to the east. The explosions have been accompanied by loud bangs that rattled windows in many kilometers away and could be felt until the Ionian coast.
The volcanic tremor has continued to rise to very high levels (as high as during the most powerful paroxysms of the past weeks) where it has now been stagnating for the past hours. This paroxysm has been quite different from most others: It seems that so far, no true lava fountaining has occurred, rather ongoing strong explosions at a duration that is truly amazing.
