Update 29/04 – 10:25 UTC
– A stain is present in Las Calmas sea this morning. No jacuzzi has been observed. This stain could be the remains of yesterday’s activity. Joke images will be online later today.

Update 29/04 – 10:20 UTC
– An amazing picture of the waters of the vent area which was photographed yesterday by Julio del Castillo Vivero. Colored waters with a lot of seagulls having lunch with dead fish

Update 28/04 – 23:48 UTC
As written earlier, Julio del Castillo Vivero was invited by the crew of the Atlantic Explorer to sail with them to the vent area. He wrote the following :
Hello, very good day with the Atlantic Explorer, the crew of Qstar and the scientists of ULPGC. I was above the volcano! A very special moment for me after many months following the eruption. I saw lots of seagulls above the main vent, eating dead fish, around the size of 10cm that was emerging to the surface.
The stain was very clearly visible today from the boat, with a green color, not super strong concentrated as used to, but quite clear.
I didn’t get seasick at all, it was very good. Sea was calm in the morning and then also sunny from midday.
Great day! Great people! Great images!
(ER : strange that there are still dead fish above the main vent – we also noticed on Jokes pictures in the middle of the week that a lot of seagulls were flying above the vent area.
The news coming in from the Atlantic Explorer is even more important as Joke has not seen any action in the sea today, which means that the volcano can erupt without a clear visual sign on the outside. Good to know is that seagulls on the vent area are indicating dead fish and thus erupting material and that a stain clearly indicates action which is more than degassing)

Update 28/04 – 22:55 UTC
– 1 additional earthquake today and if not revised , extremely shallow at 1 kmMagnitude 1.0. Time 21:32.Epicenter in El Golfo

Update 28/04 – 13:17 UTC
 1 earthquake since midnight. A M1.4 magnitude quake at a depth of 15 km on this location
– Julio del Castillo Vivero is on board of the Atlantic Explorer. Luckily for him the sea is calm reports Joke (an Ocean swell is even with calm weather often enough to get seasick!).  Let’s hope that Julio will have some nice pictures later today. The ROV will not be used today as the people on board of the ship have a bunch of other tasks. Julio has send the image below from the ship a little earlier. It shows the volcano cone at his present depth. We will have to wait until tonight to find out what the colors really mean.
I  a direct message to us, Julio writes : ERUPTION STILL ONGOING
