Activity continues with little changes, but has been lower today. Lava supply to the latest sea entry seems to have stopped after it had grown to approx. 5 hectares in size by last night. Active lava flows on the surface are in the area la La Laguna, where at least one of the fronts continues to invade some of the remaining islands of uncovered land.
At the vents, mild fountaining and dense ash emissions continued most of the day, generating a plume that rose up to 4,300 m altitude and continued to drift towards the east coast, disabling operations at the airport. The situation is likely to remain like this for the next few days, unfortunately. While causing problems on the east coast, the westerly winds create relief with better air quality for the plagued Aridane valley and other areas of the western side of the island…
Volcanic tremor, and likely the flux rate of magma, have been at similar, overall comparably low values as yesterday. An interesting 3-D animation of the relief, both above and under water, and the current lava flow field can be seen in the following video:

There has not been significant ground deformation since yesterday, except a slight deflation at the station closest to the volcano. Seismic activity has been much calmer than most days, with no quake at or above magnitude 4 occurring during 24 hours (something that can change quickly, though). The National Geographic Institute (IGN) recorded 72 earthquakes in total, out of which 5 were felt. Most of them /(48) occurred in the deeper layer at depths of 30 km or more.z
