Translated update from Enrique.
12/07/2020 - 11:30h Canary Islands. VOLCANIC
Earthquake SWARM IN TENERIFE UNDER THE BOILDER AND WEST OF PICO VIEJO. - FLUID DEPRESSURIZATION IN DEEP. - More than 350 small Long Term
Events indicating a clear depressurization of fluids by their distribution of more or less and more intense volcanic-tectonic hybrid-type previous earthquakes (or bolts) with several localized q ue allow us to put it in the Canadas.

And then, a few hours later, the swarm in the Ucanca boiler has begun with more than 350
Events registered and several dozens localized. In between socks you can see a few more tectonics.

This is not new, almost a month ago we had another one and it joins what happened in
June 2019 and much earlier in
October 2016.
It would be the fourth event of this style in 6 years, which needs to be added more than the one he spoke the day before yesterday. In fact in the previous post 640 it said "It presents itself as a triple screw that augments nothing good as it opens the magma wrench in the area to move in the next few days, so it is not discardable that we have a swarm with pressurization n included in next few days / weeks. "Today we see... and what had happened ????
For we have had another and which basically counted earlier is a depressurization of a very fluid and hot magma area with gas that passes (which moves) by a rocky narrowness at depth, like when air goes out of a balloon and this vibrates the exit zone by making a pebble that fades less as the pressure drops. In this case the valve is hot rock that opens and closes vibrating and vibrating the conduit and generating these signals.
Another way to look at it, I already commented on it is comparing it with the vocal cords that allow us to speak. The last example would be to think of the vibration and noise produced by a barracuda-type pool purifier, the more pressure the faster the fluid passes TATATATA and when the pressure is lowering the slower it is giving the blows TAC TAC. Involcán put an audition for it on YouTube and you can hear this live.

From the island they tell me that vibrations and swings are noticed, even some takeoff or dust in the area of the valley of Guimar by the Arafo volcano. Others define it as if you were on board a ship, which continue at the time of writing this post and which announces that we might still have some more movement in the swarm in the coming hours and days. Now if you play to move token and meet the Scientific Committee or / and PEVOLCA and tell us something, two in less than a month is no longer very normal, it is an abnormal situation to which you should be given the officiality or responsibility you deserve, and that the matter, which is not ballad and which has its importance.
According to that signal, it can be interpreted as hybrid
Earthquake, which has signals in both low and high frequencies. They indicate possible movement of fluids and gases.
This does not mean a new magma intrusion, but it looks like a movement in one of the reservoirs, specifically in the reservoir area located in that area between 11 and 15 km. To know if there has been a new magma intrusion we will have to monitor GPS and how the composition of gases such as CO2 and Helio evolves in the coming months to give the heading or confirmation of what exactly has happened.
Following the initial swarm about two in the morning that have located two
Events (there are more than a dozen), we have had some more of less magnitude, and as of 6 am UTC, one hour less in the Canary Islands, the tremors have begun or vibration of the conduit or narrowing that has given such a unique signal for several hours indicating the flow of gas-rich magmatic material and in the process of depressurization. Now what we need to know is where that material goes and how far and when it moves.
That's it, we could have a new swarm shortly that would indicate that the magma or flow of fluid that keeps moving in depth breaking the rock in its path in successive pressurizations, and with an increasing seismicity. This is a serious warning and indicates that this is going to get more, the system reactivates, and now we would have to monitor it more closely, which would involve a yellow traffic light as a precaution and see where it goes.
And the graph of released accumulated seismic energies doesn't need more, it keeps rising and indicating a system reactivation. Now I need more data to see how all this evolves, but the system is in clear reactivation towards an "unrest" if it continues like this, now it is just a major rebound but if it continues to rise, it will be an "unrest " in all rule (Enrique)

Although at the moment it does not represent a serious eruption warning, there are still no significant pre-eruptive parameters if it represents a path of reactivation of the volcanic system of Tenerife to worry in the mid-term (weeks or months) if you do not stop e, but surely keep on tumbling with more active phases and phases less active. If you want to go out you have to let off a lot more energy and go up, which gives us a reasonable time to get things ready.
That we will have eruption in the future, this is very clear, we have had thousands, but so far NO, this tracking of volcanic activity continues to indicate that the system activates or turns on to prepare for one in the future, of which there is no Exact date or place in the center of the Island.
As far as the type of eruption that could be the problem is that the last eruptions, except Chahorra, have been in the dorsals, and this one seems to indicate the central building and that scenario can be of two types, 1. - like the effusive eruption like that of Chahorra (Noses of Teide in 1798) or 2. - explosive as White Mountain (about 2000 years ago).
Now I leave it to them to think which one they prefer. But be warned that we could have both, first one and then the other as happened in Iceland with the Eyjafjallajökull in 2010. I encourage all the Canary Islands and I'm waiting for
Events, both from authorities and from the volcano. (Enrique)
