05/01/2020 - 15:00h Canary Islands. - THE LA PALMA VOLCANO STILL STOPS. - ANTROPIC SIGNALS (produced by human activities) IN THE TREMOR, THE VOLCANO STILL STOPS. - REGIONAL EFFORTS AND BASE ACTIVITY IN TENERIFE. - ARTICLE ON TENERIFE SURFACE RESERVATIONS. - The volcano de la Palma is stopping, it keeps stopping, that's more than clear, but there are always things that disturb us, one of them is a strange signs in the graph of the tremor. Knowing that these brands are always reassuring and in this case they all look like very local signs, surely produced by human activities near the CENR sensor.
TREMOR GRAPHICS: There must be jobs of people near the CENR station who are causing those noise peaks in the tremor or RSAM signal, so I have had to use the TBT station tremor to see that it was nothing serious, and so on yes, it's a local noise. In the spectrogram you can't see the low frequencies of the typical magma noise that reddish the bottom, which makes me very calm. Besides, there is almost no seismicity, the volcano therefore continues to stop.
The problem is the same as always, the lack of open data that provokes such situations by not being able to contrast with other stations or media that despite being able to be public and paid with public funds, they are not.
INSIDE THE VOLCAN.

in Tenerife, several earthquakes produced by regional efforts are observed throughout the island concentrating on several points of the same.
1. - GARDEN ZONE - VILAFLOR
Follow the seismicity at 5-7 km in the area, indicating the magma bag or reservoir of the intruders passed between 2016 and 2020.

2. - PHONOLYTHIC MAGMATIC CAMERA ZONE - UCANCA
Follow the seismicity at 11-15 km in the boiler area, indicating a small pressurization by the regional efforts of the bag or phonolithic magma reservoir under the Teide-Pico Viejo and the Canadas del Teide.

3. - ZONE OF THE SMOKING SYSTEM OF THE TEID
This area continues to be seismic, indicating minor presurizations in the smoke drains that climb the Teide. In this case, it is a very very small earthquake, so much of a negative magnitude.

4. - FANCY ZONE - DORSAL NE
There is superficial microsismicity at 2-5 km, a typical situation where dispersion of opening efforts caused by regional tensions affecting the island are indicated, let's see what we have in the next few days.

5. - ENEMY VOLCAN ZONE.
And of course, the area that never fails with all this, the Enmedio volcano, with a few more earthquakes. The depth is a little rare in the first two... but oh well.

And for the end I leave what is most intriguing, a publication that talks to us about a possible operating model of the volcanic and fumarolic system of the Teide- Pico Viejo with the different parts involved, gases, aquifer, the volcano and reservoirs d and magma as well as smoking pipes using data of the geophysical compilations performed throughout the Teide building.
The most interesting thing about this study is that we may not have a large surface reservoir but 3 small ones one to 2km under the SE area of Pico Viejo, another 4-5 km just under the Teide and another about 2 km under the White Mountain. More than interesting.
