Activity at the vent of the eruption on La Palma this afternoon (image: Canarias TV live stream)

The eruption continues with no significant changes. At the vent, a lava flow is being erupted and intense ash emissions create an eruption column rising to approx. 4000 m.
Although the activity has been much less noisy recently, the continuous gas and ash emissions, often in combination with little wind has been causing lots of ash fall and poor air quality in the Ariadne Valley, which is an increasing problem.
The lava flows have advanced a bit along the active northern fronts, but the northwestern flow has not yet created a new sea entry (although it might occur soon).

Tremor remains at similar levels as during the past weeks, even a bit above average.
Earthquakes continue as well at similar numbers as before, in the same areas - mostly in 10-15 km depth under the center of Cumbre Vieja, and few, but often stronger ones at 35-40 km depth. IGN recorded a total of 101 quakes during a 24 hour interval, including 7 felt ones, with the strongest being a magnitude 4.6 event at 12:57 a.m. early today.
Deformation is showing a weak trend of deflation, suggesting that the magma reservoir is slowly emptying.
