El Hierro

[Florence]

What about the seismic graphs for La La Land - I can't see any.  Is it a cover up?

[fifi]

A large earthquake in another part of the world caused the graphs to peak. The fact that some of the Canary Island graphs did not show peaks of similar size has led some Scientists and Volcano followers to believe that some stations have altered their equipment so as to not worry the population. With small scale earthquakes such as are happening in El Hierro the difference would not have been as noticeable. Donations are being offered to buy or bring in other equipment because of the need for correct data collection.

HIERRO Canary Islands (Spain) 27.73°N, 18.03°W; summit elev. 1500 m

Instituto Geográfico Nacional (IGN) reported that tremor, registered by every seismic station on El Hierro Island, continued during 12-18 October. Deformation decreased during this period, with significant inflation-deflation episodes registered by the stations located in the NW part of the island. On 12 October, at about 1430, the amplitude of the tremor signals abruptly decreased and smaller amplitudes persisted during the following days. During the afternoon of 12 October a large light-green colored area was observed in the sea to the S of La Restinga village (at the southernmost point of Hierro); the evolution of this anomaly was observed from land and by helicopter. The extension of the anomaly was controlled by the ocean currents, but a small area was detected as the emission center due to its intense discoloration and concentration. During a helicopter flight on 15 October, steamy lava fragments in this small area were observed. In the same area, during 15-17 October, frequent episodes of emission, forming big turbulent rings of gas and foaming, were observed on the sea surface. Since the night of 17 October, the amplitude of the tremor signal had decreased slowly. On 18 October, deformation further decreased and the sea-surface disruption from gases was not observed.

Geologic Summary. The triangular island of Hierro is the SW-most and least studied of the Canary Islands. The massive Hierro shield volcano is truncated by a large NW-facing escarpment formed as a result of gravitational collapse of El Golfo volcano about 130,000 years ago. The steep-sided 1500-m-high scarp towers above a low lava platform bordering 12-km-wide El Golfo Bay, and three other large submarine landslide deposits occur to the SW and SE. Three prominent rifts oriented NW, NE, and south at 120 degree angles form prominent topographic ridges. The subaerial portion of the volcano consists of flat-lying Quaternary basaltic and trachybasaltic lava flows and tuffs capped by numerous young cinder cones and lava flows. Holocene cones and flows are found both on the outer flanks and in the El Golfo depression. Hierro contains the greatest concentration of young vents in the Canary Islands. Uncertainty surrounds the report of an historical eruption in 1793.

These have been the earthquakes since 21 Oct and they seemed to have picked up again. Its reported gas was seen bubbling again yesterday in the sea and could have been one of the reasons the investigating boat was called back to port.

From Avcan

Ya van 29 sismos del día 21, lo más destacable en el mapa de la sismicidad de los últimos dias es el aumento de sismos, y tenemos la concentración de sismos en la zona marina del valle del Golfo los 3 últimos dias, que se acrecienta en las últimas horas con mas sismos en lo que parece ser un nuevo enjambre sismico, que indica la entrada de más magma en el sistema. El resto de la sismicidad sigue mas o menos dispersa pero perfectamente alineada, marcando principalmente la zona de fractura  NNW-SSE. que por cierto está alineada con la zona de erupcion en el agua. (Enrique)

Longer 29 earthquakes on March 21, highlights on the map of the seismicity of recent days is the increase in earthquakes, and we have concentration of earthquakes in the area the Valley of the Gulf marine 3 last days, which is increasing in the last hours with more earthquakes in what appears to be a new swarm sismicoindicating the entry of more magma in the system. The rest of the seismicity remains more or less dispersed but perfectly aligned, scoring mainly NNW-SSE fracture zone. by the way is aligned with the zone of erupcion in the water. (Henry)

Thanks Longships, the Kermadic Islands were mentioned as being responsible. There was a Tsunami warning given which was later cancelled.http://earthquake-report.com/2011/07/06/massive-earthquake-in-the-open-sea-far-away-from-populated-areas/

                   .....................

Current Volcanic Islands (AVCAN)
 EL HIERRO - 22 OCTOBER 2011  - Seismic activity continues to be moderate, with more moderate earthquakes located in low magnitude than other days. We continue with an important sign of tremor, with a rebound at 08:00 am and continues with more significant changes, even small explosions. The magnitude of the earthquakes between 2.3 and 1.4. New earthquakes 21.

God knows what dodgy site you get your translation from but this is what it actually says (with a couple of corrections) Not that it was worth the effort. Try using Google translator in future.

There were 29 earthquakes on 21, the highlight on the map of the seismicity of the last days is the increase in earthquakes, and we have a concentration of earthquakes in the Gulf marine Valley the last 3 days, which has increased in the last few hours with more earthquakes in what appears to be a new seismic swarm, indicating the entry of more magma into the system. The rest of the seismicity is more or less scattered but perfectly aligned, marking the fracture zone mainly NNW-SSE. which of course is aligned with the area of eruption on the water.

By the way, an apology to every one for this alarmist posting wouldn't go amiss.

OMG please look at the ign graphs something big has set all the isalnds graphs off including Fuerte.

Next time do a bit more research before crying wolf. People don't look their best with egg on their face.

Must agree florence. I honestly believe that jand should be spoken to by Admin about needless postings and also blatant scaremongering IMO

[PHo]

I second that

[jand]

All my posts have been based on facts and are not scaremongering they are factual events that are happening at the moment.

Why should I apologise for the above statement again it was pure  fact and  if you had bothered to look at the graphs on all the islands you would have seen this and also it was something big it was the earthquake in New Zealand that had registered on the seismic graphs on the islands .

Stop twisiting my words I never said something big had happened on Fuerte or the other islands .

Hate to think what state you will be in if you do Panic jand!!

As I said before if you are so worried get off the Island  to somewhere you will feel safe,,  you are going to make yourself ill!!

I always read this forum even whilst in Fuerte. I came back home on Wednesday after 2 weeks holiday. I had to stop reading this forum because jand was actually scaring me and actually ruining my holiday with worry.

Or for the real number http://www.avcan.org/?m=Animacion IGN dont record them all.

A Surtseyan eruption here (I dont think that anything as strong is going to happen in El Hierro even though it is the same kind of eruption)[]http://www.youtube.com/watch?v=VLos2k9JOBM

Volcanic tumbleweed?[]

            What the papers are saying....



The volcanologist National Research Center


The eruption off the coast of La Restinga decreases in activity. The crack is sealed and seismic episodes recur on the island of El Hierro. Ramon Ortiz, an expert volcanologist, said that the magma is seeking a new way to the surface, but bets that the new mouth is open again under the sea. He said that there may be many other active mouths but they just do not know because it is happpening under the sea.

One of the questions he was asked....

Do you certify that the main episode is over and has generated a small magmatic eruption?

"-I would say that this episode is over, that is the principal but do not know. It was thought that if you know you know how a system will work, but in the last 20 years have confirmed that even though I know perfectly medium to long term no one can predict anything reliably. Here we knew in July that could have a rash, was a small percentage has been increasing each time until we enter a phase of level four and five, in which and the chance was almost total. We knew the area but not the exact point of eruption. It could have been in the harbor and then we had problems. Then we saw that it was more than a mile so we told them that if they came to take pictures they could not. Less than a mile could have been a total destruction. " Translated badly by Google.[] http://www.laopinion.es/sociedad/2011/10/23/episodio-acabo-haber-erupciones-puntos/375840.html

                   ................

Translated article http://www.canarias7.es/articulo.cfm?id=234831
The volcano of El Hierro is showing new signs of activation with bubbling at the sea surface and changes in the color of the stain that extends in front of the village of La Restinga.
On the other hand, last night there were 50 new earthquakes on the island, between 24 and 16 miles deep, according to scientists and intensity between 2 and 2.6 degrees. The first one was felt by the population occurred at 20.00 hours in El Pinar, 16 kilometers deep and the second of 2.6 degrees was felt this morning at the border.

 Faced with these new episodes Security General Directorate has
decided that the Emergency and Rescue Group made a reconnaissance flight. The government says we can not speak of "reactivation" of the volcano until no new ground deformation detected and completed the survey data.

On Friday, as published today in its printed edition Canarias7, local authorities describe as "normal part of the phenomenon that has occurred" in the sea bubbling some neighbors said they had seen on the evening of Friday. They noted that "scientists do not rule it but did not see it."
