quote:October 30, 2011 – CANARY ISLANDS – The National Geographic Institute has confirmed this morning at the direction of the Civil Protection Plan for Volcanic Risk (Pevolca) a magnitude 3.9 earthquake struck northwest of Frontera, located in the sea at a depth of 22 miles deep. The earthquake was followed by a 3.2 magnitude aftershock which struck at a depth of 19 km. The quake, which was felt by the population, occurred at 07.46 hours and is the largest earthquake recorded in the island after the onset of the eruption south of La Restinga. The Emergency Coordination Center and Security (CECOES) received 1-1-2 calls from the towns of Isora, Guarazoca, Mocanal (Valverde) and Tigaday (Border).
The evolution of seismicity in the north of the island has increased in recent days and scientists, who are monitoring constantly all possible scenarios, still cannot ascertain what this new activity means. In this sense, they are inclined to believe that this new activity could be producing a seamount. Moreover, those responsible for the IGN have confirmed that yesterday, 62 earthquakes were reported along this region with two of them being felt by the population. The earthquake of greatest magnitude in yesterday’s swarm reached a magnitude of 3.6 on the Richter scale.
This movement has been located at sea in the Gulf area about 4 miles from the coast at a depth of 23 kilometers. It has been felt by the population with maximum intensity IV in the town of Valverde. The depths vary between 15 km and 25 km. In total, since the day July 17, 2011, the island of El Hierro has been shaken by more than 10, 615 earthquakes. According to reports from scientists at the University of Cadiz, and with reference to the deformation of the ground, this continues in two separate scenarios. The south of the island shows a remission in increasing deformation, clearly marked by the eruption process and that is evident in the data recorded in the GPS station of La Restinga. However, in the north of the island, there is an increased component of deformation component to the North and the East. (Bron
quote:31/10/2011 @ 09:36 – Over the weekend there were 148 earthquakes detected on the Island of El Hierro (from 00:01 on Saturday morning to 23:59 on Sunday night), there were 59 on Saturday, the highest one registered reached 3.6 on the Richter scale and four of these were felt by the population. Yesterday, Sunday 20th October 2011, there were 89 quakes detected, two of which reached a magnitude of 3.9 o nthe Richter scale and 7 of these were felt by the population.
quote:PEVOLVCA Scientists on El Hierro call meeting for this morning
The PEVOLCA Committee on the Island of El Hierro is meeting again this morning to review the current situation on the Island following an increase in seismic activity over the weekend, and to evaluate the information, which has sometimes been conflicting. The Committee took the decision not to take any action yesterday, but instead to wait for a more revue of analysis and meeting today.
The total count of seismic activities is difficult to keep accurate due to their frequencies, however, yesterday there were 93 recorded earthquakes, with a further 41 already being recorded before 09.00 Hrs GMT this morning.
In addition to the frequency of activity, the intensity appears to growing with 2 quakes measuring greater than 2.0 on the richter scale alone this morning.
Doubts have once again been raised about the safety of the Los Roquillos tunnel, which could hinder any attempts to evacuate the residents of the El Golfo area to the main town of Valverde to the North-East of the Island.
More news is expected later in the days once the details discussed in the meeting have been released.
This morning's Youtube clip shows a 3D graphical representation of the seismic activity that has occurred underneath the island between the 10th-30th October
quote:Second eruption imminent
Scientists analysing seismic activity on the Island of El Hierro have warned how a second volcanic eruption could be on the point of happening.
Even though scientists last week spoke of signs of the first eruption off the south coast of the island, decreasing in activity early last week. seismic activity off the opposite coast of the Island led to fears that the eruprion may simply be about to enter a new phase. Over 150 earthquakes were recorded over the course of this weekend around the areas of Frontera and El Golfo, reaching as high as 3.0 on the richter scale.
It is thought that this activity could signal that the magma is now trying to break through to the surface on the opposite side of the island.
No changes to the state of alert have been made - the Island as a whole remains on Yellow alert, with the town of La Restinga, close to the Volcanic eruption on the south coast, remaining on red alert. It has also been rumoured that the El Golfo area may also be moved up to red alert, and the Los Roquillos tunnel closed if earthquakes continue.
A senior Volcanologist, Nemesio Perez, explained to Spain's national broadcaster RTVE "What we do know is that there is activity with magma and this chapter has still not been closed," he said.
The PEVOLCA spokeswoman, Ana Vidal, confirmed the news and referred to the activity as being "great and accelerating."
Although it is a couple of days old now, this Youtube clip shows a good graphical demonstration of what may be happening or about to happen >>
The PEVOLCA committee met this morning to discuss the events of this weekend, but it was found that there is insufficient data to predict what will happen in the coming days, weeks or months.
De hoeveelheid bevingen van vandaag tot nu toe (21:04/19:04) : 252quote:31/10/2011 @ 19:29 The El Hierro underwater volcano eruption appears to again be active as magma has been reappearing on the surface of the water off the coast of La Restinga. Residents have said that the sea surface appears much darker.
quote:Data Update 01/11 – 10:37 UTC :
In our 08:19 update we mentioned a stronger harmonic tremor signal being recorded. We have to report that the harmonic tremor became even more stronger the last couple of hours (see below). A very strong harmonic tremor would increase the chance on an eruption considerably. The last earthquake IGN has listed was at 07:18 UTC. It is hard to believe that this list is complete at the moment.
quote:Important Update 01/11 – 11:24 UTC
A new El Golfo Helicopter video has been published on you tube. The quality is poor but it looks like a ‘green stain’ eruption has started in the El Golfo bay. More video will have to be conclusive, but as it coincides with the stronger harmonic tremor, it can certainly not be excluded.
We remind our readers that also in the La Restinga / Las Calmas eruption, it started with a green stain only eruption, later followed by the Jacuzzi / Burbuja and thereafter by the grey muddy like stain.
Decisive information will soon come from IGN or CSIS we reckon.

De foto van een eruptie in het noorden van El Hierro bleken dus meer gezichts bedrog dan werkelijkheid.
Maar de onderwater video beelden van de zuidkant zijn echter.
Bezig nachtje geweest.
Meer dan 69 bevingen - meesten tussen de 2 en 3 in magnitude
