Update 13/12 – 19:15 UTC

A new 4’48″ Julio del Castillo Vivero time lapse video. The original images have been altered to bring up detail of the steam coming out of the water (ER : water vapor not a volcanic cloud) . Time Lapse comprehending the period between 16.35 – 17.32 GMT/UTC With water bubbling and ‘jacuzzi’ style at El Mar de las Calmas, near La Restinga, El Hierro.

Update 13/12 – 17:21 UTC
People still looking at the eruption webcam can see clearly the drifting water vapor .
To prove our case,  we have been increasing the contrast of the Telefonica Cabildo Eruption webcam image and below is the result. Above the active jacuzzi you can see the foggy water vapor, below the Las Calmas sea without the steam.

Update 13/12 – 15:50 UTC
Those looking at the webcam have the daily difficulty of the backlight of the sun. Nevertheless the eruption jacuzzi, champagne area can still be seen very well on the Cabildo Eruption webcam.

Update 13/12 – 15:34 UTC
A REMARKABLE 3 minute Julio del Castillo Vivero Time Lapse video comprehending the period between 12.42 – 13.42 GMT/UTC With water bubbling and ‘jacuzzi’ style at El Mar de las Calmas, near La Restinga, El Hierro.  Julio combined 3 different elements with each other a) the image of the RTVC webcam (which has no clock !) b) a clock he connected himself to the video and c) the harmonic tremor graph from IGN. Thecombination of the tremor graph and the webcam image has not been published anywhere else as far as we know. Congratulations to Julio.

Update 13/12 – 13:34 UTC
Currently another interesting feature can be followed on the webcam(s) – see image below
We think, but we are nor sure for 100%, that the current activity above the vent looks like degassing bubbles, which means if this process continues from now on that the bubbles of the vent gas expansion reach the surface.

To make our case, we have been surfing on the internet and came out at the activity of the Eifuku volcano located at the Mariana Islands arc.  The activity of the volcano was videotaped by the Ropos rov (Remotely Operated submarine Vehicle). The vent of the volcano was in this case 1350 meter below sea level.  A similar kind of activity may be the case here. The images below are courtesy vulkaner.no.  People who want to find out more about these pictures can click on the vulkaner.no link.

Data Update 13/12 – 13:25 UTC
As we told you yesterday, Joke felt that she had to take the bus from El Pinar to La Restinga enabling her to take pictures from the Las Calmas sea and surroundings. The series below are very beautiful.  Unfortunately there was other weather today than yesterday (a cloud deck) and our experiment to show the vent making clouds has not succeeded today.  One picture in the series shows however a low cloud forming above the vent. It might have been also in this case purely coincidence  . If you want to see the pictures in full format, please click in the main picture screen.

Data Update 13/12 – 13:15 UTC
It is very unfortunate that the Guardia Civil helicopter is not flying above the vent anymore. It would enabled us to compare the present jacuzzi with the earlier ones.  Reader Penny  did send us a Cabildo Telefonica webcam capture of bulging water this morning.
– the jacuzzi is keeping his strength
– still NO earthquakes
– the tremor signal seems to have subsided a little unless IGN did some rescaling of the graph. Bursts are less frequent than this morning and yesterday.

Update 13/12 – 10:21 UTC – A round of honor to the players in the field
We remind our readers that what we witness right now at El Hierro is unprecedented volcano reporting in modern times. A Submarine volcano gradually growing from the sea floor to the surface. Thanks to the data of IGN, IEO and CSIC, the great images and videos from INVOLCAN, ITER and the GUARDIA CIVIL HELICOPTERES , the lively discussions and guiding in Spanish from AVCAN and in English from Jonfr and Volcanocafe , the webcams of the El Hierro Cabildo and Telefonica, RTVC and the Canary Island government and the El Pinar authority, the time lapse videos from Julio del Castillo Vivero, some internet sites (ER is only one of them) and last but not least the support of our volunteers, Joke Volta and Ian Carson, a submarine volcano has never been documented so much.  We thank all of them on behalf of the thousands of daily readers following this volcano birth in the earthquake-report.com website.

Update 13/12 – 10:21 UTC
– The RTVC webcam is showing a very turbulent Jacuzzi activity. The hydromagmatic bursts are having a growing impact on the surface waters and more than once the water is bulging.

Update 13/12 – 09:49 UTC
– Joke is still taking pictures at montaña Naos of this mornings cloud, jacuzzi and stain. The weather conditions are however totally different than yesterday, so we think that yesterdays vapor clouds may not be present today.
– As expected, a VERY large and powerful Jacuzzi this morning. How do we see this ? During the last couple of weeks the Telefonica Cabildo webcam had to zoom into the jacuzzi sometimes beyond the buoy (laid there a couple of weeks ago). In todays image the webcam had to zoom out to be able to get an image of the extended jacuzzi. The jacuzzi activity is growing every day

Data Update 13/12 – 06:25 UTC
– NO earthquakes
– Medium harmonic tremor with periods of strong bursts and periods of lesser bursts

Data Update 12/12 – 22:22 UTC
INVOLCAN new CO² data shows a considerable further decrease. On December 5  the amount of carbon dioxide amounted to 1560 ton daily, yesterday 978 tons.

Data Update 12/12 – 21:21 UTC
Lets talk something serious now :
– NO earthquakes today
– Medium harmonic tremor with bursts every 5 to 10 minutes (hydromagmatic activity – see link to paper below). This happened all the day long – see graph.
