Data Update 27/11 – 23:50 

– A total of 16 earthquakes today
– Only 6 earthquakes were M 1.5 or greater
– the extremely shallow El Golfo 1.9 earthquake from this morning was not followed by other shallow quakes(luckily)
– harmonic tremor wad severe to very strong today and is still continuing that way around midnight. The IGN graph shows very strong tremor in between 20:00 and 21:00 and very strong again with a lot of powerful bursts from 22:00 on until the time of this update.

Update 27/11 – 23:30 
Jesus Perez Quintero, the person in charge for Safety at El Pinar was aboard of the Salvamar when the ship navigated to the eruption spot this morning and this afternoon (see also images Joke Volta and Ian Carson). 3 heavily shaking videos were recorded during this trip. Collecting fresh lava stones was very important for science, a risky task but also well planned.  We have embedded 1 video, the 2 others have to be viewed via the link below. These videos are the same than showed in the Avcan facebook site.  The Videos are courtesy Jesus Perez Quintero and Avcan

Update 27/11 – 19:56 – Ian Carson reports

I cannot commend enough the personnel of IGN who have been very informative and so helpful and wanting to impart knowledge and information. If this had been in the UK, we wouldn’t have got near to  the scientists or the stones. More pictures of Ian have been added to todays Picasa image report

Update 27/11 – 17:56 – Images made by Joke Volta 
Joke Volta was many hours in La Restinga today. She enjoyed being there and looking at the action. She paid a lot of attention at the Salvamar, the ship of the coast guard who went to the Jacuzzi to pick up the lava stones and pieces. Click on this image to see more pictures of what she has seen today.

Update 27/11 – 16:20 – Ian Carson reports from La Restinga 
– Scientists back confirmed been into Jacuzzi but lots of gas, sulfur and chlorine.
– Vent confirmed at 1.8 km from coast.
– Length of ship,’ Salvamar Adhara’ for comparison purposes is 21 meters.
– Steaming stones area bigger + brown stain.
– Rocks are hot when arriving at the surface, they have to use gloves to handle

Update 27/11 – 15:46 
We have to thank the Cabildo of El Hierro, Telefonica, The Presidencia of the Canary Islands, Ian Carson, Hans-Werner, Birgit, Jean-Patrick and ourselves for this great series of images from today’s activity (.. and the day is not over yet)

Data Update 27/11 – 14:24 

– Joke just wrote us to make publicity for the Sunday El Hierro Volcano show !
– A pity for the backlight in all the webcams at the moment. The eruption is still taking place.
– 12 earthquakes since midnight
– Irregular but strong harmonic tremor on the IGN graph.
– while looking at the eruption webcam, ejected material can be spotted at regular times

Update 27/11 – 13:44 
Ian just had a talk with a geologist. He confirmed that the present erupted material (as can be seen also on the picture below) is pure lava. The Restingolita stones were mixed seabed stones with new lava.
What people are seeing today is “the next step” in the eruption process. Almost over said scientists a couple of days ago, never been that active since the beginning.

Update 27/11 – 13:44 
Below a really huge lava piece which was picked up this morning by the Coast Guard boat. The boat takes a big risk is getting so near to the eruption area. If ejected and still hot, the boat can be heavily damaged by this kind of magma.

Update 27/11 – 11:49 
We have recorded the strongest part of today’s activity and time lapsed more than 1 hour recording into 8 minutes. Enjoy the activity of the El Hierro undersea volcano. The ship (after a few minutes) is a small coast guard ship taking pictures from the Restingolitas. We hope, together with you, that these pictures will arrive in the open internet later today.

Data Update 27/11 – 10:52 
– 10 earthquakes since midnight UTC
– strongest earthquake being a M 2.3
– the remaining earthquakes having a magnitude 1.3 and 1.5
– a VERY IMPORTANT new fact we have seen tonight is a shallow earthquake at a depth of ONLY 1.9 km (providing the data is correct). If new earthquakes would occur at this depth, an eruption event in the El Golfo bay cannot be excluded.
– Harmonic tremor is medium to strong at some times. The graph below gives an overview of harmonic tremor from 8 AM to 10 AM UTC or local Canary island time.

Update 27/11 – 09:14 
The activity at the eruption area gets even stronger than before. The webcam operator just zoomed out a little to have a wider scoop. Earthquake-report.com expects more action today. A stronger Jacuzzi and from time to time a swelling geyser type action.

Sunday morning action in the Las Calmas sea

Update 27/11 – 08:50 
The coast guard boat on the image will have the best pictures. What he does is however very risky as nobody can predict the start of a subaerial phase of the eruption.

Data Update 27/11 – 08:09 
– the action which started yesterday by floating smoking stones is continuing this morning,  hot pyroclastic material is floating to the surface. Just behind a weak Jacuzzi is formed. All this can be seen on the Telefonica eruption webcam.
