18/12/2021 - 18:30h Canary Islands. - ERUPTION OF PALM ISLAND. - DAY 91 - (86+5). - 5 DAYS REST ON SURFACE AND STOPING. - FIRST SESMIC CALM - STILL PRESSURE AND GAS TO GO OUT, HOPEFULLY THEY COME OUT WITHOUT A LOT OF PUMP. - This ends and there are many interesting things to tell, we have the first seismic calm since
September 11 without earthquakes for hours located that there are no and in addition this calm allows to see things that with the noise of tremor not we saw, among other things the noise we humans make or noise of anthropic origin that is clearly marked in the tremor. The telesisms that are in the form of peaks are also marked, especially that of Indonesia of 7.3, but also others closer, today two peaks of earthquakes in Greenland and Italy.
This noise is also felt in the form of planes or helicopters passing by and resounding over the Taburiente boiler, forming 100% entropic signals in the TBT sensor and it is known to only occur in tropic activity hours, of 8 from the morning to 8 of the afternoon more or less.
I have been warned of the presence of gases in low areas as well as of an anomaly of gases in the bulb area, with a bubble about 50 m from the shore that they have gone to investigate, natural thing in this process if we think that to close the main conductor, gases looking for other routes and it seems there are some fumes or skins (no vapor smoke) in areas over that conductor, with some emission points.
In the main crater you can see perfectly how the gas continues to come out, tiled, besides the water vapor, as in this video of volcanic. In addition, they have formed precipitation in many areas that have been upholstered with a white color due to the rainfall of salts, carbonated surely. Yellow areas are due to sulfur deposits and possibly some more halogenized salts such as F, Cl and others.

These gases, such as CO2 or SO2 can be accumulated in low areas, basements and closed premises and move to oxygen, being dangerous to get in there as there could be breathing problems and even die of choking. We saw this in some videos a few days ago.

In fact it has come to my knowledge that many animals have been found who have suffered this in the lightbulb area where there are cats, rats and many dead birds, at least they are evacuated. The possible bubble point.
This gas pressure can be seen as LP03 low, but LP04 goes up and that indicates pressure in the lower part of the pipeline that developed following the NW dorsal. And it's that those gases have to come out somewhere.
But this is not new, there are areas that have been bubbling for years like the point of the Caldera de Taburiente, which with this volcano has renewed its energies, or even hot waters like those of Fuencaliente, whose heat comes from the volcano.

If we analyze the seismicity of the last days, we perfectly appreciate the activity in the dorsal NE ( black ) which continues, since it was the dorsal by which the deep magma climbed to the surface reservoir at 10-12km, but in changed also obese rva a relaxation of efforts with a general deflation of the island when seismically activated the interdorsal areas (yellow) and oddly there is a point of two fractures that cross in front of the port of Naos where they say the bubble is, when less curious, since the g I really did it before I knew this information.
In the last hours, since the past 6 am, there are no localized earthquakes, and it is not a mistake, barely see signs of seismicity on the Island, which is the first seismic calm lap we have since the swarm began on 11
September. This fact is one more step and confirms that the volcano has stopped, we'll see if it's finished, we have to wait a few days, for caution and because this volcano has come out palm.
We still have something to give for this finished, it has to go cooling, some areas will take years, it has to be gone degasifying and most of all people have to go back and start thinking what we will do with the slate that has put us on the na tourism. In addition to the volcanic cone, some tube of lava will have to stay, some area of the coladas field too, but I am a supporter of the reconstruction of some runners who go through the laundry as it was done with the coladas of San Juan and that much people recover their roots to that one palm land, hard as few, but with enviable
Weather, a paradise when the volcano allows it. I hope it stays still for many years. In fact between the eruption of 1949 and the previous one of the Charco in 1712, there were 237 years of calm. I'll just leave it right there. Good night.
