Volcanic activity in Canary Islands 2019

[jand]

There is lots of discussions on the internet that the landslides have been caused by rainfall but other people are saying there has been no rain in the area of the landslides as the rain was just in the north of the island.

Photo attached as an example of the area of rainfall.

"ollow the seismic activity in Tenerife and other parts of the Canary Islands. Comparison of seismic information by ign and involcan: Compare Earthquakes Located in the last week (from 10 to 17 October)

63 earthquakes located in Tenerife and surroundings by involcan.
51 earthquakes located in Tenerife and surroundings by the ign.

One no longer knows what to think, but it is clear that the ign has a problem, they are staying behind with so much nonsense and disinformation and their space is being replaced by more professional people and delivered to volcanic surveillance, but with many less economic resources, That is.

1.- we have had seismic swarms in Tenerife, in several areas like in the south dorsal with a remarkable swarm with 18 microdisks located in less than an hour the night of October 11 at a depth of 5 At 8 KM AND 2 more localized earthquakes entered the 12. th. They align in direction n-s indicating local opening efforts of the dorsal from below.

2.- the area of the caldera has not been released with almost a dozen Events by large areas of it and almost all microsismicidad, that yes with some earthquakes already above magnitude 1, more important of 1.4 In the south of Pico Viejo, very close to the eruption of the noses of the teide and in what would be the caldera of ucanca about 12 km deep. This, also that just like the previous case, align in direction n-s giving an opening signal, form 120º indicating pressures from below and also tells us a small pressurization of the system of the magmatic chamber that is found by That area according to all studies. Everything goes in the same direction, it's getting ready.

3,- the teide does not pound, several earthquakes around it indicate that this pressurization, affects the hydrothermal system with some earthquakes and microdisks in the upper area, and even one of negative magnitude at only 1 km of Depth a couple of days ago. Seeing that the co2 of the guayota keeps rising that goes up, slowly, something is cooking down there to slow fire. The later the more beast will be on the way out. What we do not know is where, it seems that it will be by the caldera, but it cannot be ruled out or clearly indicate any particular site.

4.- North of the teide and west, along the northeast dorsal extends an area of seismic activity that indicates opening efforts of this area.

5. Finally is appreciated a connection or alignment with the area of the volcano in the middle, making it very clear that the system is assembling day by day and preparing to take the leap towards something more important. At the moment you have to wait and fortunately has not started seriously

At the end of the month, to that on October 27-28, we will have a new episode of intense gravitational forces with Tides that reach coefficients of 110 over a maximum of 120 that will surely affect the canary volcanic system and Who knows if we will have the annual intrusion in the form of a powerful swarm of hundreds of earthquakes as it has happened in the last 3 years (October 2016, October 2017, November 2018) in the adeje area then In later months he has migrated giving seismicity to the caldera and the south dorsal. We'll see what happens (Enrique)."

No Expert but have noticed the graph for El Hierro this morning.

On the link below click on El Hierro then click on all the other islands the lines are really thicker on El Hierro  compared to the other island graphs and El Hierro shows lots of movements and if you click on the 2nd circle El Hierro the yellow band is half way up the page.

Have added examples of Tenerife for today for comparison.

It might not mean anything but will wait to see if there are any updates or an explanation ?

" Long term earthquakes or "LP" in the northwest dorsal of Tenerife and maybe more, Canary Islands, Spain.- at 10:33 pm this morning you see a small Earthquake in the seismogram of maci But after 10 minutes a clear sign of a different Earthquake or Earthquake appears, a " long period " Earthquake or " LP " to which it has followed another 11 minutes later and more things I will explain later, As a more than possible sign of tremor.

The second Earthquake of 10:43 h UTC that if it has located the ign in the area of the nw dorsal in Santiago del teide with a magnitude of 1.6 and 14.5 km deep. More specifically it has been in the area where the road comes from the caldera and has witnessed numerous eruptions in the last 500 years as they show the numerous cones and castings of the area like the mouth of crab ( See Map).

Es2019umppr 19/10/2019 10:43:53 28.2715 14.5 km m 1.6 Mblg Santiago Del Teide. Itf

Surely they will review it, and it is not a sign, but several, and also 10 minutes later appears another sign again that has not been localized by the ign for the moment. Surely check them on Monday and change them, they lower the magnitude and will do with them what they want, but something is clear, what marks the signal, is what marks the sign, that does not take it away Nobody.

In fact this activity on the nw dorsal was predictable as it was the only number or area that we had left to move this way throughout the island of Tenerife, therefore we already have the three bibs with Seismic Swarms And Type LP earthquakes in the last 2 years. This type of signal memory indicates pressurization of fluids in depth, it's like the noise of the water network when it closes a tap and paste a blow known as a battering ram.

And if this was little, this is not everything, after these signs of these earthquakes there is another sign, different, almost an hour of spasmodic tremor and draw several horizontal lines in the sensor. This noise could be compared to the one who makes the pipes when the water flows through them very fast and sounds throughout the building. In fact this signal indicates that magma has started to move under the island after this swarm, that is inferred from this sign in the seismogram. Now it's time to wait where it goes

And now that we can wait? This magma that moves, is because it has broken something and will do it until you find another point or resistant and sealed area that will not let you migrate more where you will start to pressurize or take pressure, causing clear this the consequent seismicity associated with this pressurization That will allow us to locate where it moves.

These next days will be more than interesting, at the moment we continue with activity in the area of the south dorsal, an Earthquake in the area of the coast of fasnia of magnitude 1.5 and 24 km deep and finally A lonely Earthquake of 2.5 in the port of light of Gran Canaria (Enrique)"
