Actualización 29 / 02 - 23: 55 UTC
- The day ended with only 4 earthquakes
- almost no HT
- No stain or jacuzzi
- we are very curious for the next couple of days. If the present situation continues for another week, Pevolca might decrease the alert levels

- 4 terremotos hasta el momento actual
- In the many mails we received from Joke yesterday and after midnight today (yes, she often works until after midnight), something escaped our attention. An earthquake at 05:02 yesterday morning with an epicenter to the east of the La Restinga reef (in between El Hierro and Tenerife).
In a message later yesterday and before Joke had seen this earthquake location, she told us about a stain in that same area. When climbing montaña La Restinga, she usually looks both sides of the La Restinga. She found it strange to see a stain in that part of the sea (especially as we had no more stains above the main vent for many days). She indicated the stain spot in her image series from yesterday afternoon, adding a map with the location. There are no signs that this is a viable reason for a new emission vent as the quake was reported at a depth of 20 km, but the least we can say is that this event is rather unusual and not immediately explainable, unless the stain drifted away from the main vent.

- 2 great videos for Volcano Lovers : with special thanks to AVCAN, who gave us the lead for them. We have embedded them in our Volcano News updates.

Actualización 29 / 02 - 07: 55 UTC
- 3 terremotos so far today. Magnitudes : 1.1, 0.8 and 1.3. Depths in between 7 and 12 km.
- unchanged tremor armónico
- Continua micro-seismicity
- No visible mancha o jacuzzi on the eruption webcam


Actualización 28 / 02 - 23: 55 UTC
- 8 terremotos hoy
- no revival of HT but as seen in the Las Calmas sea, degassing is still continuing
- the new depth data shows that a Surtseyan eruption is imminent IF some stronger activity would start. This may still happen during the current eruption process.
- Joke has been following a 3 night INVOLCAN information course. Tomorrow more about this course.

Actualización 28 / 02 - 19: 20 UTC
- The depth of the cone is now 100 meters according to twitter from Cabildo de El Hierro, @PrensaElHierro. They also comment that there is a decrease in seismicity, deformation and gases release.

Actualización 28 / 02 - 16: 00 UTC
- A lot of new pictures from Joke Volta, all photographed today

Actualización 28 / 02 - 14: 22 UTC
- We have learned that webcams are now working with dedicated power generators as there is a power cut in La Restinga! In the image below we can see one of the generators, top left, and the position of the webcam.

Actualización 28 / 02 - 13: 28 UTC
- Eruption webcam is back online after operators visited the site and fixed the issue.
- No jacuzzi can be seen at this moment and no further earthquakes have been recorded since this morning.

Actualización 28 / 02 - 10: 28 UTC
- Tenemos cut 2 parts of the main article as it was getting far too long. The E Hierro volcano is already an eruption in 33 parts (including this latest one). The link to part 31 and part 32 can be found at the bottom of this page.
- As written earlier in this article, the Ramon Margalef will disappear from the scene after the current bathymetry session. Spanish authorities have now published a calender of the instances who will replace Ramon Margalef. New ships from various departments will scan the bottom of the Las Calmas sea at least already during the months of March, April and May. The volcano cone will certainly be included in the various sessions.

Actualización 28 / 02 - 08: 28 UTC
- This is probably the first morning since many months that both webcams are out of order. Blind again ! Let us hope that the problems are only temporary
- Terremotos 6 hasta el momento actual. magnitudes : 0.6,0.6,0.7,1.0,0.7,1.0. Depths in between 11 and 20 km.
- unchanged tremor armónico
- Continua micro-seismicity
-
Now that the eruption goes on smoothly but far from spectacular, Joke is showing also some other views of the island. Since many months Joke has been far better than any expensive advertising campaign of the Cabildo showing the beauty of El Hierro. They simply are not aware enough of the value of Joke's images. Not even a Thank You from the authorities who are spending a lot of money on advertisements in glossy magazines, trade fairs etc. Of course we encourage these campaigns, but being a little more "enjoyed" about Jokes work should certainly not be exaggerated !

Actualización 27 / 02 - 18: 10 UTC
- A boat was seen on the webcams navigating above the vent, a forbidden navigating area, coming from the West and on its way to La Restinga port. Julio del Castillo Vivero made a short time lapse of the boat's adventure.

- Cabildo de El Hierro has created an application which has some nice information on El Hierro. The application is for iPhones and Android smartphones and can be downloaded free of charge. Haga clic aquí para mas información.
- Morning images of Joke Volta

Actualización 26 / 02 - 09: 46 UTC
- We have been busy since many hours in reporting earthquakes in Taiwan (M6.1) and Siberia (M6.8), both very dangerous but for various reasons without major damage or casualties. Links to these extensive in-depth articles can be found on the frontpage
- 2 terremotos desde la medianoche
- no visible stain or jacuzzi this morning but continuing micro-seismicity (very weak earthquakes)


Actualización 25 / 02 - 23: 35 UTC
- We have ended the day with Terremotos 14 enumerados. The latest 7 at depths varying in between 10 and 12 km.
- Involcan / Guardia Civil helicopteres video from yesterday February 24

Actualización 25 / 02 - 16: 20 UTC
- 7 terremotos hasta el momento actual
- we have the feeling that the activity is increasing slowly. The faint jacuzzi is still visible on the webcam
- we have just added 4 pictures from Joke. Click on the thumbnails below to watch them.

Actualización 25 / 02 - 13: 20 UTC
- 5 terremotos so far today. Rather new is that 2 of these earthquakes has been located at a depth of 33 and 34 km. Epicenter of both are below the island itself
- el jacuzzi is back alive, faint indeed, but just like yesterday it can well be seen on the eruption webcam, even with the sun glare of the afternoon
- ER lector Sissel could not sleep well last night and recorded the webcam. Spooky lights are traveling the Las Calmas sea. The webcam operator, who is doing a great job, was focusing on the ship later in the night and created another eruption-like image. We are fearing now that when the real eruption starts, we might think it is the Ramon Margalef !

Actualización 25 / 02 - 08: 53 UTC
- 3 terremotos so far today. Magnitudes : 1.1, 1.2 and 1.3. All epicenters below land, but the locations are more and more to the Orcilla area (the lighthouse west of Tacoron).
- no change in tremor armónico
- Continua micro-seismicity
- no (webcam) visible stain this morning, although the haze over the vent area is still present
- after the more intensive (and very detailed) geology course at La Restinga where Joke was informed about all geology aspects of the island, INVOLCAN will give an evening course at El Pinar on February 28, 29 and March 1. It looks a little silly to us that 2 different organizations are organizing a course almost at the same time. A "light" version of the geology course which Joke followed should have been a great way of honoring the preparation work of Mr. Ramon Casillas Ruiz.
- Each time some action is tgoing on near or above the vent(s), Involcan / Guardia Civil Helicopteres is present to make a detailed image / video / measurement report of what is going on. Below the (less spectacular) images of yesterday's helicopter flight/ Click on the thumbnails to see the series in our Picasaweb.

Actualización 24 / 02 - 23: 15 UTC
- 6 terremotos hoy
- Tremor armónico to minimum values
- Los population of El Hierro has currently 1403 foreign residents. Most of them (725) are residing in Frontera, 447 in Valverde and 231 in El Pinar. Joke told me before that a lot of the foreign residents are from Venezuela. Apart from Chavez also the link with migrating family members leaving Europe (or Africa) towards South America plays an important role. Most of these immigrants, some of them escaping from the Franco rule, sailed from El Hierro. They could hide very well for the military or the police before starting their dangerous trip.

Actualización 24 / 02 - 14: 48 UTC
- We have a clear reactivation of the volcanic activity
- a faint jacuzzi is present all day long
- HT seems to pick up a little bit
- 5 terremotos hoy
-Ramon Margalef is still cruising not only in front pf the coast, but also near the main vent

Actualización 24 / 02 - 11: 36 UTC
- an additional earthquake occurred at 09:16 and brings the total to 4 today.
- Los image below is quiet spectacular. We have some faint jacuzzi since this morning, but the distorted image above the vent shows that the total wide of the picture (wide angle at the moment) has a higher temperature than the rest of the sea. We haven't seen this since a while ! The image is showed as captured from the webcam.

- minimal harmonic tremor (like the last couple of days)
- the webcam shows a faint jacuzzi this morning (not permanent, but often enough to see it)
- Benthos Buceos, one of the diving companies at El Hierro, made a dive along the southern coast recently. They were happy that the sea recovered partly from the total marine life destruction from last October
