Henry from Avcan has reported:


..In the evolution of the depth of the earthquakes, still watching in the shallow area to about 9 - 10 km, but something is different, and is that several of these shallow quakes are not in the Gulf, but in the central zone of the island..

,,In the graphic of the evolution of the seismic energy released accumulated at the moment it seems that continues, though more slowly that if from the 22nd release of energy is more or less continuous.,,

Good morning, Simon Day in La Palma to defend his theory of the collapse of Cumbre Vieja. Interesting what he says at the end of the interview on the connection between islands: "iron, La Palma and Tenerife appear to be separate volcanoes." However, there is the possibility of a connection, but to a great depth. Fifty or a hundred kilometers from the surface... There's even a suggestion that says that when an island is active, the other is not. This suggestion, which was initially made by Juan Carlos Carracedo, is very interesting to understand how the Islands were developed and how they are connected. "

Simon Day: "the consequences of a collapse of Cumbre Vieja can be very serious"..

..Therefore, it is more sooner or later, collapse. That is, La Palma has a tragic fate, sentenced to generate this chaos."We know that many collapses of this kind have occurred in the past in the Canary Islands." Are landslides that have left scars on the Islands, as a new Summit, here in La Palma; or the Valley of La Orotava and Güímar, Tenerife. So what I am talking about is a phenomenon which has its proven history. It has happened in the past and will happen again in the future. "The problem is to calculate when can happen again."..

..By the way, if someone has been set, I think that the magma moves (vibrations and microseismicity) and it seems that goes to the area of la restinga again, indicate this deformation and in fact according to IGN station HI-09 la restinga has been raised 2 cm more in the last hours and 1 cm in HI-08 (Henry),,

Good evening, we must also be aware of the central part of the island, was recorded last night another Quake 11 km. border, close to where there have been the last at these depths and that have nothing to do with the shallow Gulf swarm, that area may be candidate to a rash, especially if earthquakes out there continue to occur or if it produces a new mass of magma intrusion, which for my it would be the final by having several advanced roads and for supporting the island an overpressure, as well as indicate the GPS.

- 2 earthquakes have been added by IGN
- GPS deformations :
* No ultra-rapid data yesterday and today at La Restinga (REST), but the Rapid data (better quality) show a very strong increase  of 3 cm yesterday (against the ceiling of the graph!)
* same story at El Pinar (PINA) although the lifting was "only" 2 cm
* same story at Frontera (FRON) with a vertical lifting of about 1 cm.
We expect todays Rapid data later today (comes several hours after the Ultra Rapid data (black crosses))..

,,This is the last presented by the IGN curve with the recent deformation of the island surface at La Restinga. Those in the last days of the GPS measurements, an increase of approx. 30 mm and is now currently stands at 70 mm (arrows). The graph covers the period from June to September 2012th Consider the big picture, then there was a movement of minus 70 mm in late June to now plus 70 mm - ie approx. 140 mm, or 14 cm.





But this for the measurement point HI 09 at La Restinga strongest deformation values ​​can be either close to a magma displacement or another intrusion of magma and  gases from the Earth's interior. The pressure in the magma chamber builds up further and the surface bulges like a balloon into the air. Global view these values ​​are still low. There were already volcanic areas with a deformation of more than 300 cm.
Of the seismicity was yesterday for weeks one of the quietest days. Only two earthquakes up to ML1, 7 in El Pinar in 21 km were recorded.
For islanders and visitors there are no restrictions. Of all the geological processes on the island surface is nothing to feel and life takes its usual course.
The Canary Islands Government has now published a regulation that governs the fishing or the fishing ban around the island for the next 6 months,,

,,The scientific meeting the night of the volcanoes in Fuencaliente, has served to contrast such divergent positions on the volcanology in La Palma as Simon Day, who presented the model of the catastrophe that would cause the slippage of Cumbre Vieja or, on the contrary, the proposal of the prestigious Spanish geologist Luis González de Vallejo, who defends the "great stability" of this volcanic edificeposition much less impact media as above, but with a solid scientific basis;Vallejo González was overwhelming to the several hundred people who gathered in Fuencaliente and stressed that the building Cumbre Vieja is "very stable", even more than the Teide-Pico Viejo, with a payback period of this phenomenon which was 80,000 years. This fixes one of the uncertainties generated by the theory of Simon Day, which is unable to forward a time frame to the collapse that forecasts of this volcano, i.e., that according to the British scientist could be this year or within several thousand years. In fact, specified that major landslides in the Canary Islands and in the Atlantic Islands generally occur because they grow very fast on a very weak base, which tends to give up due to lack of stability. In the case of Cumbre Vieja, estimated that still remain you more than a thousand meters so lost that stability and a large landslide might occur.Lizards along with coralThe Complutense University geologist stressed that this conclusion responds to scientific evidence, not to the development of theories, in a clear allusion to Day. González de Vallejo has participated in a study that is still in phase of publication and that goes to show for the first time that in the Canary Islands have been mega-tsunami (giant waves of more than 50 meters) and the causes that generated them.Among the conclusions is that in the Canary Islands even though there was evidence of the existence of large landslides that caused mega tsunamis to come into contact with the sea, now have confirmed scientifically, to discover for the first time in the Islands 'tsunami deposit', that were not known until now."There have been many landslides (La Orotava, new Summit, the Gulf) in the Canary Islands, but fortunately we have found deposits of tsunamis, because if not continue at the level of speculation", explained. The places where you have made these findings are in Agaete (Gran Canaria); Teno (Tenerife); and high stone (Lanzarote). It is of "huge tsunami deposits, probably the best preserved and most complete in the world". Scientists have found in these locations fauna marina along with continental on high surfaces. "We found lizards along with corals," he explained.A few tsunamis have much seniority and produced by landslides resulting from the fact that the Islands 'grow to extremely fast speeds".,,

Note that 3 are in the swarm of the Gulf and the last three seem a superficial enjambrito that has been at the center of ls island between 10.5 and 12 km, who joins this morning 10 km a bit more to the North. Today we continue as previous days, have you noticed any tremor, noises or knocks, in some areas of the island. Also have noticed again vibrations in many areas of the Gulf (Sabinosa, the Llanillos, Los Mocanes, Las toscas, leads and Tigaday), El Mocanal, San Andrés, Tamaduste, el Pinar and la Restinga. As for odors have not reported. As for the strange behaviour of animals have not reported. Events of whistles, hums and dizziness have also been reported with pain in the ear drums, phenomenon that is produced by a resonance in the ears of high frequency sounds. For who wants to know more about the buzzing, here is the wikipedia page, and the truth is that also has occurred in Hawaii. http://en.wikipedia.org/wiki/The_Hum remind everyone that it is very important if you feel something of all this, it is convenient to report it to the IGN have documented what was in addition to the importance that has in case of monitoring the possible opening of an eruptive mouth area... It is very important. (Enrique

Joke Volta asked this question to Enrique from Avcan:

,,

Enrique answered :

(AVCAN) No Joke I think, I think rather indicating otherwise, the island is subject to regional efforts that are affecting all the hotspots with magma moving under the island... and my personal opinion is that I think that these efforts could be prelude of an activity more intense earthquake-volcanic the next few days, something that will come possibly preceded by several moderate earthquakes in the area of the Atlantic Ridge, hopefully it's not so...

Comments on the Avcan Facebook Page by Maria Diaz:

,,La dirección (a gran escala) de todos los sismos canarios es más o menos NE-SW, en paralelo a los ejes mayores de las islas más alargadas (Lanzarote, Fuerteventura, Tenerife), aunque luego aparecen otros ejes menores en otras muchas direcciones. Ese gran eje de sismos e islas ¿indica por donde aprietan las placas continentales en movimientoo es debido a otro fenómeno?

Address (large-scale) of all the Canary Islands earthquakes is more or less NE-SW, in parallel to the axes of the more elongated Islands (Lanzarote, Fuerteventura, Tenerife), but then appear the other axes children in many other directions. That big shaft of earthquakes and Islands do indicates where tightened continental plates in proceedure is due to another phenomenon,,
