Caletillas Quote

Of course this tsunami threat to the peninsula is nothing to do with vulcanism in the Canaries
But under the present situation with El Hierro is is not just commonsense to include all the Canary islands in this as surely the percentage margin risk is higher now in the Canaries with the present situation ?

As per no one taking much notice I have spoken to many spanish families and spanish business people on my travels between Corralejo and Caleta and can assure you a lot of people are taking notice of what is happening in El Hierro.

As a high percentage of the English on Fuerte do not watch Spanish Tv and do no read .papers then surely this is the main reason they wont know whats going on in El Hierro?

I looked through many sites yesterday evening and sorry cant for the life of me remember where I found that graph.

Good morning guys...are they stones being thrown up on the web cam ?

Morning

It looks to me like blackstones are floating in the sea and there looks like there are lots of them ?

[SurfJames]

Morning folks....

I think they're shadows from the small waves jand.

The activity seems considerably less than yesterday. Also an on-shore wind for a change.

Data Update 25/11 – 08:26
 - 4 earthquakes since midnight UTC
 - Strongest earthquake today : M 3.1 at a depth of 20 km at 02:35 UTC
 - The shallower depth of the earthquakes from last night, was not confirmed today. The depth is again at 20 km
 - The harmonic tremor graph shows more and longer bursts than the last couple of days.-
 - Air quality at La Restinga : nothing unusual
 - Weather outlook : winds from the North East – 14 to 15 knots and wave height max. 1.6 meter (better for viewing webcams)

Update 25/11 – 08:00
 - In her "Just got up" report, Joke Volta reported a white foaming activity in the green stain
 - The eruption webcam has been redirected early this morning (we don't know whether this is the result of the tough discussion Joke had last night with Alpidio Armas, the President of the Cabildo of El Hierro). Joke said to Mr. Armas that "amateurs" are handling the webcams and that the "world" was looking at the activity, citing the number of users from outside El Hierro. She said also that this was the worst publicity the island could get.
 - If the faint activity on the eruption webcam will be confirmed later on, we have to speak of a major shift of the active vents as we have the impression that the stirring is much closer to the coast than before. We are anxiously waiting for new GPS data. (Update 08:15 : in the meantime the camera has been

Everything fits to the eruption in the North

The great spot who is leaving the volcano in La Restinga eclipsed Thursday what is happening in the North of El Hierro, where the location of small tremors in seismicity and the increase of the CO2 tax aims to more shallow magma movement.

The Seismicity in the North of El Hierro is declining to the point that on Thursday there were only three earthquakes, however, and as reported by the Committee on scientific work at the direction of the Plan of Civil protection by volcanic risk (Pevolca), have appeared "often a type of volcanic signal (lp) at stations on the North Coast». These volcanic signals long period (longer period) amount to small interrupted tremors associated with magma movement.

The Director of the National Geographic Institute (IGN), María José Blanco, rejected full mean already have sign of tremor in the North and, therefore, an eruption, but it admitted that the magma is moving significantly off the coast. And does it in positions more shallow if it attends to the concatenation of small tremors linked to a seismicity more somera in recent days in the North, between 15 and 18 kilometers deep.

In addition, these two elements is compounded an increase in the pressure of the gases in thermal magmatic system. The last measurement of diffuse emission of carbon dioxide (CO2) from the Instituto Volcanológico de Canarias (Involcan) made the day 20 round the 2,200 tonnes per day (400 tonnes more than four days earlier), a value equivalent to 6.34 times the average normal value on the island.

CO2 is the mover of the eruptions, that is why some experts have the feeling that will be before a preeruptive stage in the North.

[jand]

Update 25/11 – 13:32
 - PEVOLCA has decided that all evacuated people are allowed to return to their houses. As the La Restinga people were already allowed to sleep at home, this decision was taken to allow the return of the families of the Las Puntas area who had to be evacuated after the M 4.6 earthquake from a couple of weeks ago.
Pevolca maintains however the Red Alert for La Restinga (municipality of El Pinar) and the yellow alert for the rest of the island.
The only Civil Protection extraordinary measures that are currently maintained is the closure of the beaches of Puerto Naos and Tacorón as well as the maritime NO-GO area (radius 4 km).

One Spanish persons quote.

NOT UNDERSTAND ANYTHING! Yesterday there were signs of long period, the vertical deformations, corpse gases desarretados, and today everything is NORMAL, i.e. does already not have CRISIS SISMOVOLCÁNICA? What has gone down in the Middle? Has it disappeared the tremor? NO, follow with periodic explosions. We have several days without signs of seismicity in the N? Today no one sense of 3.1 and yesterday several earthquakes to profundiades less than 19 km and several concentrated on the coast of the Gulf against Los Llanillos, as in previous days. Have disappeared for days gases? NO, the own PEVOLCA indicated yesterday in his communiqué journal as follows: "indicate that the analysis of the Institute Volcanológico de Canarias have detected an increase of diffuse emission of CO2" and such emanations are triggered, lease: "the results reflect the registration of an upward trend of the diffuse emission of carbon dioxide (CO2) into the atmosphere by the volcanic edifice island of El Hierro who has reached the 2,186 ± 87 tonnes per day;" a value equivalent to 6.34 times the normal average value for the diffuse emission of carbon dioxide (CO2) in the island of El Hierro (345 tons per day) "what has past?" WHO IS AFRAID THE PEVOLCA? AT THE BORDER OF MAYOR? Everything indicates that, at least for now, the crisis continued sismovolcánica: to return to the situation of normality are needed at least one week or fortnight without tremor, without almost shallow earthquakes, with disappearance of gases, with.... so many things that a change from one day to another and I forgot!WE ARE STILL IN TRAFFIC LIGHT RED IN THE RESTINGA! AND YELLOW IN THE REST OF THE ISLAND! Who fits sizes despropositos and descordinaciones? The only logical answer I can think is that the PEVOLCA is not responding to a possible situation of risk in El Hierro, but economic, political pressures... If it were not because they are entirely legal responsible for the management of the risk that happens around this sismovolcánica crisis it would be to send them to hell. All the gods of Olympus I hope that does not happen to people in the coming days. And one final thought to those who say that they will have data to say this, the only thing that may have to say that against all data deás is a ball of plastic which look to the future.

Something happened about 1830 on the graph for El Hierro.

DIARIOELHIERRO.It is, drafting (14 11 25, 2011: 15 hours)
The Roquillos tunnel and roads that remained closed in El Hierro because the sísmico-volcánica phenomenon have been again opened to traffic after to confirm a reduction of seismicity on the island.
It was reported that today the Director of security and emergencies of the Canary Islands Government, Juan Santana, during the course of a conference held at the Cecoi de Valverde. Santana was accompanied by Councillor for security and emergencies of the Cabildo of El Hierro, Maria of Carmen Morales and the Director of IGN in the Canary Islands, María José Blanco.
Santana also explained that the guaguas of the military unit of emergency (UME) which were prepared for an evacuation at La Restinga, return time to the military barracks Anatolian sources of La Caleta. Also, they reopen its doors the Lagartario and the Ecomuseum of Guinea.
The only extraordinary measures for Civil protection are maintained at the moment are the prohibition of access to the coves of Pinar and Puerto Naos, as well as the maritime exclusion zone.
On the tunnel of Los Roquillos, the Pevolca requires that the General Directorate of road infrastructure will be a work in the area where there were defects in the build-up, so will be this institution, together with the Cabildo of El Hierro, where they will have to specify when and how will open the lane towards border-Valverde, which remained closed for the studies being undertaken.
These decisions are taken due to the decrease in the likelihood that occur a seismicity of high magnitude exceeding 4.5 on the Richter scale, maximum level IGME established so that landslides may occur on the slopes of the tunnel. Furthermore, quakes that are taking place are occurring at a depth of over fifteen kilometres.
On the other hand, has been to put three accelerometers in the escarpment of the adjoining slope of the border tunnel, allowing greater control of possible landslides.
As preventive measures, the equipment of the Red Cross and the EMU, as well as communications, transportable stations network and the port of advanced command (WFP) will remain in El Hierro.
EVOLUTION OF THE PROCESS
On the volcanic earthquake crisis, the Director of IGN in the Canary Islands, María José Blanco, it was reported that "we are in a more relaxed setting in the last fifteen days there has been a relevant seismicity, the magnitudes of the movements have been below the 3.7, horizontal deformation does not have a noticeable pattern and the vertical show a downward movement with the exception of the Gulf." "In the latter case, Western and Sabinosa health well point to stability", he said.
Regarding the eruptive process of La Restinga, Blancoo stated that it follows its course, as evidenced by the extent found in the tremor which confirms that the Volcano still emitting matter and depending on what it is colored differently.
Since the first bathymetry by the scientific equipment of the ship Ramón Margalef there has been a decrease in the height of the volcanic edifice, which is to say that sectoral frequent landslides of underwater eruptions there are.
While the level of emission of gases has been an increase should be specified according to the Instituto Volcanológico de Canarias (Involcan), this is understandable because magma is still moving.
Finally, María José Blanco said that the scenario about a possible eruption in the north remains open but pointed out that the situation is not clear and that it is not imminent at the time.

Translated.

The evolution of the cumulative released seismic energy curve seems is moderating its rise, releasing increasingly less energy.

This may be due to the system is relaxing or on the contrary it has become to engachar as a few days ago still is soon to be confident, that the last time he did this, ended with a 4.6, will can do this in the next few days? or will the opposite can continue relaxing, releasing increasingly less energy?

We will see that it is the case, while watching the gases and deformation, does not appear that this relaxing, especially gases (Henry)
