El Hierro

This has been taken  from a BBC Science/Horizon report .

''Scattered across the world`s oceans are a handful of rare geological time-bombs. Once unleashed they create an extraordinary phenomenon, a gigantic tidal wave, far bigger than any normal tsunami, able to cross oceans and ravage countries on the other side of the world. Only recently have scientists realised the next episode is likely to begin at the Canary Islands, off North Africa, where a wall of water will one day be created which will race across the entire Atlantic ocean at the speed of a jet airliner to devastate the east coast of the United States. America will have been struck by a mega-tsunami.

Back in 1953 two geologists travelled to a remote bay in Alaska looking for oil. They gradually realised that in the past the bay had been struck by huge waves, and wondered what could have possibly caused them. Five years later, they got their answer. In 1958 there was a landslide, in which a towering cliff collapsed into the bay, creating a wave half a kilometre high, higher than any skyscraper on Earth. The true destructive potential of landslide-generated tsunami, which scientists named "Mega-tsunami", suddenly began to be appreciated. If a modest-sized landslide in Alaska could create a wave of this size, what havoc could a really huge landslide cause?

Scientists now realise that the greatest danger comes from large volcanic islands, which are particularly prone to these massive landslides. Geologists began to look for evidence of past landslides on the sea bed, and what they saw astonished them. The sea floor around Hawaii, for instance, was covered with the remains of millions of years` worth of ancient landslides, colossal in size.

But huge landslides and the mega-tsunami that they cause are extremely rare - the last one happened 4,000 years ago on the island of Réunion. The growing concern is that the ideal conditions for just such a landslide - and consequent mega-tsunami - now exist on the island of La Palma in the Canaries. In 1949 the southern volcano on the island erupted. During the eruption an enormous crack appeared across one side of the volcano, as the western half slipped a few metres towards the Atlantic before stopping in its tracks. Although the volcano presents no danger while it is quiescent, scientists believe the western flank will give way completely during some future eruption on the summit of the volcano. In other words, any time in the next few thousand years a huge section of southern La Palma, weighing 500 thousand million tonnes, will fall into the Atlantic ocean.

What will happen when the volcano on La Palma collapses? Scientists predict that it will generate a wave that will be almost inconceivably destructive, far bigger than anything ever witnessed in modern times. It will surge across the entire Atlantic in a matter of hours, engulfing the whole US east coast, sweeping away everything in its path up to 20km inland. Boston would be hit first, followed by New York, then all the way down the coast to Miami and the Caribbean.''

The General Direction of Security and Emergencies carries out a simulacrum of emergency earthquake in Tenerife

The event, planned over two months, involved some 300 members of the Canary Islands Government, the State, the Cabildo de Tenerife and the municipality of El Rosario
print news Print this page

Authorities during the press conference of the simulacrum
The General Direction of Security and Emergencies, under the Ministry of Territorial Policy, Sustainability and Security, carried out a simulation of a seismic emergency in the municipality of El Rosario, Tenerife, with the participation of 300 troops.

Thus, under the technical direction of Security and Emergencies, a device made up of the Emergencies and Rescue Group (GES), the Canary Emergency Service (SUC), the Autonomous Police, the CECOES 112, the Emergency Military Unit ), the National Police and its unit with search dogs, and the Civil Guard with the Group of Rescue and Intervention in Mountain and with agents of Traffic.

Also participating were BRIFOR and firefighters from the Cabildo de Tenerife, the Local Police and Civil Protection of El Rosario and Cruz Roja, as well as members of the College of Fisheries and the College of Architects of Santa Cruz de Tenerife. In the simulacrum was also present, as observers, a group belonging to the army of Portugal.

The exercise was based on the assumption of a seismic movement of volcanic origin causing damage to buildings and infrastructures, with deaths, injuries of diverse consideration and evacuees that were to be housed, all in several scenarios of the municipality of El Rosario.

El simulacro ha servido para evaluar numerosos aspectos del sistema de Protección Civil, como son el Plan Municipal del Rosario, planes de evacuación de colegios, validez de las infraestructuras destinadas a albergue, desarrollo de la estructura de dirección de emergencias para múltiples víctimas en diferentes zonas, así como la organización de radiocomunicaciones en emergencia, coordinación de grupos de acción y para ejercitar técnicas específicas de rescate, desescombro y búsqueda.

The Deputy Minister of Environment and Security, Blanca Perez; the Deputy Government Delegate, Guillermo Díaz, and the Mayor of El Rosario, Escolastico Gil, agreed on the importance of doing this type of exercises to improve coordination between the different administrations involved in a scenario of this magnitude, with different scenarios and multiple victims .

Seismic Swarm on the South Ridge, Tenerife, Canary Islands, Spain.- these last 48 h have been more moved than initially appeared. There were several signs in the spectrograms that did not locate them first and have now relocated after reviewing them, at the moment we have a dozen more or less aligned in the n-s direction of the south ridge of the island of Tenerife.

If the seismicity of the last few months is observed, the active zone on the south ridge in the last few days is aligned with the activity area in pico viejo and associated to the Northwest Ridge in the last two weeks.

If we go to the seismicity of the last 3 months it is appreciated that both this swarm on the South Ridge, and the activity of the old peak in cañadas, as activity in the valley area is in a nw alignment - SSE. The difference between these points of activity is that it is increasingly (Enrique).

''Swarm on the island of Tenerife

Since the 28th of October, until this time (15:00 UTC on 31 October), the National Geographic Institute has located 22 earthquakes with epicenters near the population of vilaflor, in the south of the Island of Tenerife. The depth of the events is between 3 AND 9 km and its magnitude between 0,8 and 2,0 mblg. None of them have been felt by the population. Another three events with similar features were also located in the same area last July.
This Swarm-shaped seismic activity lies within the parameters of normality in active volcanic areas, as is the island of Tenerife, and does not risk the population.
At the ign's GPS deformation stations on the island of Tenerife, there have not been any values that may be considered abnormal.

''Seismic-volcanic swarm on the South Ridge, Tenerife, Canary Islands, Spain. In principle today no new low-magnitude earthquakes have been published in the ign catalogue, although if it appears to have been recorded, as some of the low-magnitude earthquakes are observed in the spectrogram of the seismic station that could be some Earthquakes more in the area and which could be localized and published in the ign catalog when reviewing the data as examples are the signs that are valued at: 05:07, 05:47.

In the earthquake map of the last 90 days, the latest Seismic Swarms Can be fully appreciated with a concentration in the form of in-depth grapes and a set of surface events rather than clear. In addition to the one in the s-SW area of pico viejo continuously, it looks like we have had two points in the red-Purple time of the south ridge these last days and the one we had north of the complex Teide-Pico Viejo in yellow.

Little more can be added today but wait to see if this is a timely pick-up and it stops and no more is known in years or on the contrary it is reactive past a few days. (Enrique).''

Latest report from Enrique regarding a possible LP earthquake Tenerife this morning .

Firstly I have also copied one explanation of an LP earthquake :

''You also get long-period (LP) earthquakes under volcanoes as bubbles form and escape from the magma during its ascent. Unlike VT earthquakes, LP earthquakes gradually begin and then fade away rather than being abrupt events. So, if a swarm of earthquakes under a volcano is a combination of VT and LP events, it is a pretty good sign that the earthquakes are being caused by magma moving into shallower parts of the volcano. However, as the magma gets closer to the surface, VT events tend to go down as LP events increase. They can also occur as hybrid (or mixed) earthquakes that have some of the VT and LP characteristics. ''

''Volcanic.- possible long-term earthquake this morning, Tenerife, Canary Islands, Spain.- this morning between 02:35 and 02:39 at station is clearly visible the presence of one that could be an earthquake LP or long period in a clear way. Let's see what they say at ign or involcan, but this signal is important.
Although its origin is still unclear, it seems to indicate that it is a long-term earthquake. The signal in question also appears in other ign stations such as or the, which is a powerful natural signal, with sufficient energy to be recorded by several seasons, discarding the possibility of local noise Or a local signal, derived from human activities. (Enrique).
I leave you some documents on volcanic seismicity both before and during an eruption that are more than interesting when you know what is going on with how little you see in the spectrograms, as shown in the images of this Post.

At the moment nothing unusual, simply a sign that has the whole aspect of a long-term earthquake, which has already occurred on January 14 this year 2017 or more recently on September 18, 2017. (Enrique).

Volcanic stones have recently been found in the sea near to  beach in Gran Canaria.

''Volcanic pumitas appear on the beach of La Garita
05.11.2017 | 00:03
The beach of La Garita appeared yesterday afternoon with pumice and volcanic bombs in some areas of its coastline, as neighbors from the coastal neighborhood could observe, who even took some of the water. These floating stones emerge after the emanations of the eruptive process and come out afloat and the marine current brings them, in this case to the coast of Telde, although they are not dangerous.''

Latest report by Enrique regarding the new earthquakes listed by IGN.

Translated.

''Seismicity in Tenerife, Canary Islands, Spain.- in the revision of the ign data have appeared several earthquakes and exponential in the catalog that had not been located before. I will start by those who have located in the area of the swarm of wines, a little more to the east of where the seismicity occurred a few months ago and in what would be the extension of the south ridge to the north. In addition, a couple of earthquakes have appeared in the area of the volcano in the middle and on the coast of fasnia in what would be the extension of the nw ridge.

Finally today, there have been a couple of localized earthquakes located in the area and fasnia area. If we look carefully at this new seismicity, we see that they are re-placed at 120 degrees, but this time between dorsal and dorsal in what would be the dorsal areas. In fact the earthquake earthquake is in the area where the swarm of early October 2016 took place in the prolongation of the ne ridge.

In the center of all this we have the area s of the old pico viejo - el teide in las cañadas. (Enrique).''
