La Palma (Canary Islands (Spain)): The lava flow remains active, and has already constructed a sizeable new lava delta reaching out perhaps a few 100 m into the sea. At the active cone, the lower vent continues to produce a lava fountain and feed the main lava flow.
The vents at the summit were seen generating dense ash columns drifting east towards the ocean. Here are some impressions of how the scene looked at around 1 p.m. today.
...29 Sep:
Since the violent re-start of activity on Monday evening, the eruption has been going on with more or less stable lava output from the vent, and volcanic tremor has been stable. During this morning, a tendency of increasing activity seems to be manifesting itself.
Interestingly, more quakes have started to occur again, mostly at 10-15 km depth under the central part of the volcano. There were 6 quakes of magnitude 3.0 or above and 21 quakes between 2.0 and 3.0. The latest magnitude 3+ quake occurred only 1.5 hours ago, at 11.13 a.m., and was felt again by the local population.

Late last night, the lava flow reached the sea.
As the eruption continues to effuse lava at steady rate, the most advanced lava flow made rapid advance it seems during yesterday. It looks that it traveled approx. 1 km, passing north of the cinder cone of Montana Todoque to arrive and descend at the sea cliff at Playa Nueva.
