VERY IMPORTANT Update 19/03 – 17:02 UTC
- ER reader Roland (see comments) has given us the lead to a report of the University of Las Palmas de Gran Canaria showing the still erupting submarine El Hierro volcano at a depth of 70 meter (this is 18 meter less than the last published data from the IEO High Tech bathymetry equipment!). What nobody could accomplish so far, has been done by the quite simple ROV E-Wally on board of the SOS-Oceanos, Q-Star, Atlantic Explorer ship by the scientists of the Universidad de Las Palmas the Gran Canaria.
- The images have been captured on March 14 as the date on the images reveal. The images are of course foggy as a lot of suspended material is polluting the water.
- No doubt that Q-Star and the University has also some video footage that they will probably release later on (the pictures are probably screen captures of the video).
We are however VERY PLEASED that all those who cooperated on this mission have proved :
a) that the depth of the erupting cone has decreased to 70 meter
b) that the eruptive process is not yet entirely finished (at least it was not after the date that Pevolca said that the eruption stopped).
Joke was “very excited” on March 14 after talking to the crew of the Atlantic Explorer as they stated already then that the ROV made images of glowing lava. As we could not see these images, we brought the news rather minimal.

Very Important Update 26/03 -08:21 UTC
- AVCAN was the first to bring the news semi-officially, but the joint partners Cabildo de El Hierro (Mr. Alpidio Armas) and Telefonica (Movistar) have decided that the webcams are NO longer needed to show the still active Las Calmas sea.
Multi-billion Movistar gives up on El Hierro
As feared by many of our followers, Movistar telecommunications of Spain and the Cabildo of El Hierro have decided to shut down the webcam broadcast of the submarine volcano activity at La Restinga, El Hierro.
As the cost of the operations is literally “peanuts” for such a huge telecommunications company, the major part of the people following this eruption from the beginning have a hard time to understand this decision. Thousands of webcams are operated all over the world and they are just showing the weather!
As long as CAP is operating at El Hierro, a fast reactivation of the still ongoing process is possible. After many months of following operations and time needed to get it working, we are 99.5% convinced that it will be far too late to get the webcams to work again if the volcano reactivates.
As said earlier on, the cost of operating the current webcams is almost nihil ! Why ? As we have seen the last couple of weeks, maintenance is already an absolute minimum (lenses are very rarely cleaned) and the webcam zoom, angle and other settings have internet distance commands. Bandwidth is absolutely nothing for a company like Movistar.
If Movistar and the Cabildo would decide to remove the equipment (we do not know that yet), the cost would be an X-Factor more than continuing operations.

En er zijn de afgelopen dagen weer een paar bevingen geweest die duidelijjk aanwezig waren.
Een 2.7 en een 2.5

quote:
Update 03/04 08:01 UTC
Is this a sign of the awakening of the volcano ? To early to tell, but what we have seen so far today is the renewed activity of the feeder area at El Golfo. 3 of the 4 earthquake epicenters are located in the El Golfo area. The strongest M2.5 quake below the (new) volcano-vent itself.
4 earthquakes since midnight, the last one being the strongest. The 2.5 earthquake will have been surely felt by islanders and brings the memories back from the multiple earthquake they have felt a couple of months ago.

Update 02/04 18:43 UTC
- A video published by IGN shows a lot of degassing effects at depth of 100 to 150 m. We believe that the video has been captured by the Salvamar during his excursions the last couple of days. The water was very clear while videotaping? We congratulate CSIC with this video.

Maar als je dat het complete verhaal bekijkt dan is het nog erg rustig.

5 small earthquakes on 12 May

Update Mon 14 May 18:42
A slight increase of seismic activity has been noted recently. On 12 May, 5 small quakes occurred in the western part of the island at depths of 2-17 km. It is unlikely that this is a precursor of a new eruptive phase, but rather reflects residual magma movements and minor tectonic adjustments at the recently emplaces dikes beneath the island.

Het rapport over de vulkaan uitbarsting aldus volgens Dr. Carracedo
quote:
Forty years after the Teneguía Volcano (La Palma, 1971), a submarine eruption took place off the town of La Restinga, south of El Hierro, the smallest and youngest island of the Canarian Archipelago. Precursors allowed an early detection of the event and its approximate location, suggesting it was submarine. Uncertainties derived from insufficient scientific information available to the authorities during the eruption, leading to disproportionate civil protection measures, which had an impact on the islands economy based primarily on tourism, while residents experienced extra fear and distress.

Voor de rest ff het eerder genoemde linkje volgen omdat Earthquake report het rapport van de Dr. heeft mogen publiceren

Earthquake swarm continues - new magmatic intrusion ?

Update Tue 05 Jun 11:13
The earthquake swarm at El Hierro volcano continues. Yesterday, a total of 16 quakes including one of magnitude 2.9 were recorded. The quakes are clustered around the 15-20 km depth beneath the El Golfo bay, where a new magmatic intrusion could be taking place. The harmonic tremor signal has risen slightly as well.

update Sun 03 Jun 16:43
After weeks of almost no activity, a small earthquake swarm has started yesterday. During the past 36 hours, 12 mostly very small quakes have occurred at depths mostly around 10-20 km in the area NW of Frontera. This possibly indicates that magma is still occasionally moving under the volcano, but unless the intensity of earthquake swarms increases a lot, it is not likely that a new eruption is in the making.

More volcanic activity on El Hierro
The National Geographic Institute has reported eleven earthquakes on the island of El Hierro over the last few hours of today (Thursday 14th June 2012) with a magnitude of between 1.7 and 2.8 degrees on the Richter scale. According to their website, the IGN states that these earthquakes have been recorded to the west, southwest and northwest of the town of La Frontera at depths of between 20 to 24 kilometers.

The first of these earthquakes was recorded at 04:40 to the west of La Frontera, at around 20 kilometers depth and the last, of 2.1 magnitude, at 07:48 to the North-west of La Frontera, at a depth of 21 kilometers. The earthquake of the highest intensity, 2.8 degrees on the Richter scale, was recorded at 06:05.

It has not been reported if any of these quakes have been felt by the islands population.

Magnitudes have been high, with one reaching M 2.8. All depths in between 19 and 26 km. According to IGN this is normal and part of the seismic process and not the eruption.
