I understand playing jokes but that seems a bit serious!

30/12/2021 - 18:00h Canary Islands. - THE LA PALMA VOLCANO STILL STOPS. - THE ADVANCE LAVING FORWARD. - THE SESMIC ACTIVITY IN TENERIFE IN THE ADEJEZONE AND VILAFLOR CONTINUES TO BE NOTICED. - The Palma volcano continues to stop, there is no deep seismicity for days and the superficial seismicity (some just a few hundred meters deep) is decreasing slowly, in addition to being little concentrated and diffuse, which indicates a scattering of efforts along the way of the most active dorsal has been the NNW where the eruption point came from.

Where more seismic efforts are concentrated is in the area of the surface reservoir at 10-13 km under the old summit, where in addition the highest intensity or magnitude in the last 3 days, highlighting two of magnitude 2.3.

The volcano continues to degasify and the best thing is to see the video of yesterday's IGME, where you can see AEREA VIEW FROM YER DEL CONO.

And in some area, there are still small gas vents or fumes showing very high temperature material inside like this video from today's INVOLCAN:

Following Hawaii's example, sometimes it's easier to do things about the laundry itself without removing it and what is done is straightening and compacting the laundry area to put an alternative detour as soon as possible, which is seen perfectly in this v Idea of the cross from La Laguna, it is the most practical, fastest and economical option. There will be time to do better. By the way, firefighters are throwing water over the warmer areas to lower the temperature and avoid problems.

In Tenerife however the activity in the area of Adeje continues to remind us that this island is active and with several prominent earthquakes, but that is not a thing of now, comes from behind, and I do not talk about 2004, comes from much more back, from the decade of the 80 nothing less. I recommend you to read this PDF of the IGN that was published a little over a couple of years ago due to the occurrence of a major swamp in the area, it comes very well to catch up on how the situation is in Tenerife.

The list of the last three days, leaves us this view, with a small swarm with 3 earthquakes located on the 29th of this month between 6:38 and 6.40h and which indicates a small pressurization of the magma in that area 5-7 km and also as the area of Vilaflor notices some of that pressure and gives some seismicity:

But it is not the only thing that moves, in the area of the Caldera de Ucanca and under the Teide-Pico Viejo Building, there is another area with magma that is sensitive to these efforts and moves, specifically the reservoir or phonolithic magmatic camera that is found between 14 and 11 km deep.

However there are several areas with bags or sacks or magma reservoirs in Tenerife that give place to seismicity when the island has regional or local efforts, and that they could start moving towards the surface if they receive enough contribution from the more from the bottom as already ha past April 2004, October 2016, November 2017 etc.... but they weren't energetic enough to reach an eruption fortunately. In La Palma we had 8 swans and the 9th eruption occurred. We continue that it is not little and we are vigilant for what could happen. A greeting and a lot of encouragement. (Enrique)

Good ones. Enrique could you explain the signification of the red lines you have drawn on the maps. A million 🙏💕
