El Hierro Volcano : Yellow alert – Salvamar Adhara spends a couple of hours above the vent “filming”

Camera used by SCIC for underwater filming
Update 30/03 – 15:42 UTC
– Joke was (of course) in the port at the return of the Salvamar Adhara who spend a couple of hours above the vent. Based on what we have seen in the past weeks and months, we know that if the Salvamar Adhara remains a while on the sea, it is not for water sampling only (takes very short time). Bathymetry was done yesterday by the BIO Hesperides, so bathymetry should be excluded too. So Joke asked Maria José Jurado, the CSIC representative on board, if she had worked with the floating video camera (it is a camera on a rope pulled by the Salvamar Adhara, not a ROV). She said yes, we did.
Joke continued asking Maria José about what she has seen on the camera. She said that she had some interesting material, but she had to analyze it further on. She also said, that when the quality would be good enough, CSIC will send it to the Gobierno de Canarias to publish the video.
Joke also asked : was there still some activity ? She said : Yes, we still see some gases coming out of the vent. Joke continued asking : also gases at the surface ? She said : NO.
We will publish Joke’s images from the boat, spectators, camera on board, a few jelly fish in a while.
ER comment : nothing new here of course, at least nothing which surprises us. The jacuzzis we have seen for many days in a row are absolute signs of further degassing. The main question remains, is there still lava coming out of the vent. The last time we know for sure that that was the case was on March 14 when the ULPGC ROV made a video recording of it. The latest bathymetry data from CSIC did tell us that the cone was at 88 meter. But this depth was measured at the end of February ! All frequent El Hierro eruption followers have 1 major question. How deep is the crater rim at this moment ? Is it a coincidence that the Salvamar Adhara starts filming again 1 day after that the BIO Hesperides measured the depth of the Las Calmas sea floor or cone ? Probably yes or probably not. At least we know that fresh erupted lava was seen by the ULPGC ROV on March 14, and there are NO indications that this pattern has changed since then. Does this mean that the depth will be less ? Not necessarily. Let us all hope that the results will be published soon in the website of the Gobierno de Canarias.
Update 30/03 – 09:59 UTC
– Joke told us that the Salvamar Adhara has just been spotted at the main vent, probably taking water samples
– On Jokes images (click on the thumbnails below), the main vent can well be seen as well as a far bigger colored area. There is doubt whether this is current coloring or a stain. We go for the stain.
Update 30/03 – 09:59 UTC
– Joke just send us a morning report. When walking down the lave fields to La Restinga, she stumbled in a AA lava field (thick sharp lava flowing out of a crater at a slow speed) but fell luckily in a lapilli field (small volcanic stones falling out of the sky during an eruption – more or less like thick ash). It is a little painful but everything is still functioning (including her cameras)
– While driving down with the bus this morning, Joke saw a jacuzzi, but in the meantime he disappeared again
– Joke told us that she saw technicians at the webcam mast ! Let’s hope that they will leave the webcams untouched as we will never see them again in time if necessary ! As politics are against any further “bad news”, we have no hope at all that they will reactivate the webcam.
– 1 earthquake since midnight.
– continuing microseismicity
– NO change in horizontal GPS deformation
Update 29/03 – 22:20 UTC
Julio del Castillo Vivero has created a fantastic high resolution panoramic image with 60 images from Joke Volta ! (they regularly share their work). The result El Hierro as a color palette
Picture info : 180 meters above sea level – Taken today (29th March) – Mountain Dácila – Finca José Pérez, locals call it Montaña La Restinga

Update 29/03 – 21:20 UTC
– The BIO (Buque de Investigación Oceanográfica) has made a short bathymetry mission stop at El Hierro today during his return trip from Antarctica. Spain has an Antarctica base and during the months November to February, the Antarctic peninsula is merely ice free.
– And to make the day complete, here are the beautiful evening images of Joke Volta
Update 29/03 – 21:04 UTC
– The Spanish Army is really good in public relations. IGN needs to take an example on them. In a press report on the Armada Española website this evening, the bathymetry mission was highlighted.
“El buque ha realizado varias líneas de prospección en una cuadrícula de trabajo situada en las coordenadas: 27º 40´N // 27º 30´N de latitud y 18º 05´W // 17º 55´W de longitud, para determinar el punto de mayor altura del edificio volcánico y comprobar posibles variaciones desde el último levantamiento batimétrico.”
Human translation : The vessel has done several rectangle routes under the coordinates : 27º 40´N // 27º 30´N de latitude y 18º 05´W // 17º 55´W longitude to determine the highest point of the volcano and check any possible changes since last bathymetry.
