Stromboli (Eolian Islands, Italy): The new lava flow on the upper Sciara del Fuoco that started yesterday remains active and has increased a bit. Frequent incandescent rock falls detach from it and tumble down the steep slope to the shore.
At the vents in the crater terrace, strombolian explosions continue at rates of 15-20 per hour. Overall, it seems that the volcano is on an increasing trend of activity right now.
La Palma (Canary Islands (Spain)): The activity remains elevated. After yesterday’s surges of lava from a new fissure system south of the cone, lava fountains returned to the main vents at the cone, first in form of a round dome-shaped fountain of very liquid lava from the lower vent (see previous update with video), and later as a taller, more gas-rich jetting fountain from the summit vent which had been very active especially in the early phase of the eruption.
The latter activity has continued throughout a very stormy and rainy night and into this morning, then decreased a bit although it still produces fountains as of this update. The generated ash plumes rose to up to 3,500 m altitude and drifted east where it continues to disable the airport, now closed for 6 or 7 days in a row. Many airlines have canceled flights to La Palma altogether for the whole time up to spring next year due to the uncertainty whether the airport is operational or not, and whether they can actually fill seats. Requests to travel to the island likely have dropped massively, further damaging its economy that already suffered a very hard blow from the eruption.
