Many thanks to all the people (among them a lot of volcano lovers) who have send us donations. May we ask the people of El Hierro, reading this page, to use our I HAVE FELT IT form when they feel the current earthquakes. The way you feel it will give us some additional information on what is going on (written on December 22 at 19:46 UTC). Click on this I HAVE FELT IT link. You can write in your own language.

Happy 2016 for all those coming to look around the corner now and then.
It has been rather calm lately. Recently only the earthquake below was worth mentioning but that is already some days ago too.

2 new earthquakes . The first one a strong one at 34 km depth with a Magnitude of M3.2 and the second one a M2.2 at a depth of 30 km. The second one has approx. the same location as the first one (see map below). Something is happening down there but to be honoured as a new crisis, the number of earthquakes should increase considerably. Also to be said is that in that specific area, the magma was not able to break through the rock layers above, not even with very strong earthquakes.

A M2.4 at 30 km depth earthquake earlier today (see google map for precise location epicenter). As you can see below, the same area than the earthquake 2 days ago.

We have not forgotten about El Hierro but no more earthquakes since Sunday

2015-12-06 12:52 UTC
2 new earthquakes in the deeper zone South-West of the island (29 to 35 km). A shallower series in the 20 to 25 km range would be a significant change.

Thats a while ago. A relatively strong earthquake in the new cone eruption area. To follow up the following days and weeks.
Magnitude 2.8 at a depth of 12 km.

An earthquake to follow up. M2.7 BUT at a depth of 22 km (almost all of the other earthquakes in that area were at a depth of +30 km) right on the western tip of the island. Especially the depth is interesting. The earthquake can be based on an intrusion or can be the result of the stress of the volcano itself. The near future will give us the answer.

Contrary to what we expected during the earthquakes from last week, the western tip deformation station HI05 showed a slight deflation instead of an inflation.

No more El Hierro earthquakes since Sunday

2015-11-22 23:30 UTC
A second M2.2 at 30 km earthquake today @ 17:18 UTC - Same epicenter area

2015-11-22 14:01 UTC
3 earthquakes so far today in the Canary Islands area however only 1 can be linked to the activity below El Hierro. Magnitude : 3.1 at a depth of 33 km.
The quakes we are describing are happening in the same direct area and all at an approximate same depth. Also they are relatively powerful. Some of them are felt by the islanders.

New M2.3 @ 35 km depth earthquake to the West of Frontera. Too soon to say for sure that magma is rising again but the least we can say is that the the indications are going in that direction

2015-11-20 20:15 UTC
New slight earthquake but nevertheless in exactly the same area and at the same debt that the November 18 ones.
In 2014 this particular area got very strong earthquakes but the magma underneath was not able to break to a much more shallower depth.

El Hierro may be dormant for a while, but the earthquakes (even weak) are continuing below the island. Just waiting for another crisis and/or eruption. Iceland shows today what partly happened on El Hierro in the Las Calmas sea, a short-lived fissure eruption (remember the many whirlpools along the coast at the time of the eruption).

This evening people on the island felt an earthquake since long time. A M3.8 off the coast at the western side of the island was responsible for this. NO specific tremor on the graphs. Depth 16 km is still very deep.

We are sorry not to have posted more information on El Hierro, since late July. A lot of earthquakes in the world and now recently the Iceland Bardarbunga volcano are part of the reason. Here is the list of the El Hierro seismicity over the last 28 days.

    • Armand Vervaeck says:

      Thanks for telling us Jan, Looks that people are working in the area of the seismograph. Yesterday the same happened in between 07:00 and 17:00 (indicates human interference). Today it started at 08:00. Volcanic action is always coupled phenomenons like tremor but also volcanic earthquakes Armand

  1. Meredith says:

    The seismograph is showing some activity, a deep but small earthquake

    • I just reviewed the seismographic records of the other 6 Canary islands, when I detected that the strongest tremors obviously are since begin of December recorded at tenerifa and not at El Hierro. all other islands show similar currently quite levels ( despite a tremor in the signals) Both seimographs work but write confusing data - officially the wave recorder is "fuerra de servicio" (out of service) since over one month ( and was NOT EXCHANGED despite the ongoing crisis) . The second graph obviously has received a shock by the last and extreme solar event, a proton storm that took place on January 07 (protons > 1000.pfu.) and maybe just the computer has to be restarted.
      here the links to the data sheeds .>

      hopefully some expert here might explain us what goes on there? thanks

  2. the geological situation on the canaries is one of the most less explored in the world , One reason is: the Canaries are situated on a common kind of plateau or microplate that reaches up to 3700. Meter below zero. Offisde of that plateau the atlantic has a depth of 5000 meter in average. The thing is, the sea currents have covered that plateau ( that maybe has a rather rough shape) with at least 1- 1,5 km of sediments. that obviously makes it impossible to find out more about the shape the fundaments of the islands The most volcano systems are roughly known. The activity in El Hierro is rather a scholar event for spanish geologists :Learning by happening. Currently seismographs and GPS systems serve for all theories about an existing magma chamber and the size of the system. When Spain joined the EU, the EU kind of sponsored the first geological examination of the Canaries in modern times. the result were not published but serve meanwhile as a basic for insurances to calculate geoligical risks on Europes most frequented Holiday destination.Mainly british geologist squarmed all over the islands. What they found out was not a real joy for the Canarios, who were absolutely ripped rather ruined of by the EU, Their touroist business failed m asl most cant afford to rebuilt their houses suitable to the million of Eu laws and prescriptions . Last not least , when the geologist found A cracks runs through the southern part of la isla bonita ( La Palma) the medieval sea battle (> admiral Nellson between Spain and the British Empire started all over. ff 2

    • f*** here writing---the comment 3 times dissapeared while writing by a time out function. to contiunue: That magma on a hot spot does not make strong tremors as it does not contain gases I dont want to explain: there is a coincidence of hot spot activities to so called solar SEPs ( solar proton events) . all activity phases on the canaries sive 2011 followed solar SEP events and similarcoincident events coud be obvserved at other hot spot systems(shield volcanoes or calderas such as sakura Jima Sinabung ETna White islands) and we have a medium strong SEP one since yesterday 6 UTC with > 10 ME Protons > 10 pfu.. If the canaries have a large magmachamber, than it would be rather deep (10- 16 km compare yellowstone. around 8 km ) and is not yet filled up . I don`t know what explains that the island is lifting upwards . Recently Swiss team found out that eruptions on hot spot volcanoes( most of them supervolcanoes) dont work by overpressure caused mainly by gases a such as H2O, Hs, Co2, SH2, as common volcanic systems, they have even magma chamber so large that overpressure could not even occure. hot spot supervolcanoes break their way free even through 10 km stone ( from that momernt on when their magma chamber is filled up) just by their sheer mass and the physical Buoyancy at the upper part of the magmachamber.
      additional to the previous post: By the way...Not to say, the islands would at all rather " slippy"... The only but also most interesting thing published at that time ( research 1998)was the research vessel found the missing Northeastern flank at Mount Teide, but so far away from the island (I rememebr 30 km) that experts were astonishe (and the mystery remained) as there was not any natural force known to them ( until 2004?) that could have the force to do that. was its an gigantic flood wave reported 11.500 B C, caused by the surrender of Atlantis? PLatos report ends at the point when it says:" And Zeus spoke" (third ppart is missing) ( or threw this thunderbolt. Don`t throwna nuclear bomb into any hotspot!!!) . There is no trace found yet on the fllor of the Atlantic: How can such an island totally dissapear? If then by an seldom event which happened at Thera 1500 BC known as " minoic eruption, in real explosion,a strong activity phase had accumulated large amounts hydrogen and othere explosive gases below the island, those reacted and exploded , twhen the activity was colling down Stones from Santorin were found as far as in the arctic

    • Armand Vervaeck says:

      Sorru about that - reason is the automatic refresh who reloads the page every 15 minutes. Easy for most people just following this story, but a pain for those writing long stories. We will leave this comment untouched at this moment, but we want to make clear that this story is not our story. We report facts and we try to refer to proven mechanics of volcanoes rather than trying to speculate on the unproven elements. There are sites who are specialized in these theories.

    • thanks no problem just to write it again brought me in hurrry so i couldn`t correct it better finally

      Armand Vervaeck says:
      . We report facts

      but what are the facts? Anything what happens or is done : Tremors can`t say anything about how strong especially such a volcano might erupt.
      please correct me if i am wrong:

      If there is a magma chamber ( is suppose yes and its estimated to have 8 km in diameter and some km in depth) in this mantle plume then it does currently fill up. I think it still fills up as quakes remain in 10- 16 km depth and it may take longer to do so. as long as the magma chamber is not completely filled it will not surge further upwards and: perharps the magma will recced again as it did in March 2013
      “cite” and we try to refer to proven mechanics of volcanoes rather than trying to speculate on the unproven elements.
      so what causes the islands lifting up and subsidizing again) the magma in 12 km deep or the gases or air the inflation compresses below the island,Or: Is the island lifted up from a depth of 10 km?
      Thats with the Sun is new ( but prooven by NASA and MPI=)and someway would turn many geological theories upside down . To become a geologists requries to follow also scholar theories about what causes Earthquakes.which energy makes it.
      The things is: NASDA solar program has brought up many new knowledge about the sun, what would even require a new theorie. However if there is any change or new realisation it may take hundred years until it is recognized by everyone and will also stand in a school book.
      out of my own research
      I knew activity will increase when I saw the data of new proton storm -
      So (joking) it could do nothing else than dress myself a prophet and make some money with it

      There are sites who are specialized in ( denying?) these theories.
      NO you are making a good work. best volcano and quake site so far
      I was living on the canaries for 5 years und thus I also was interested in the Canaries geology .I also read a lot, what I wanted to say that all about the Canaries ( differently to ETna or other Hs systems) rather theory based on seimsographic and GPS data
      best regards!
      Helmut Munich/ Germany

  3. Manfred Betzwieser mentioned that there is a bad weather advisory for tonight (6 meter high waves). This would explain the increase in activity

    • Linda Kirby says:

      Could this be due to the 5.1 quake in the Atlantic Ridge?

    • Armand Vervaeck says:

      No, definitely not Linda. Probably the rsult of the waves. If so it will decrease normally tomorrow morning UTC

  4. Christiaan says:

    First of all all the best for 2014 for you Armand, the followers of this website and all the people at El Hierro.
    Looks like there have been some quakes when looking at the CTAB and CTAN stations starting after 17.00 UTC. Not yet confirmed though, so could be wrong. Maybe you can have a look.

  5. New deformation data shows an increase on many stations.

    • Armand Vervaeck says:

      Thanks Max - was a little late with my update today - remains a special situation!

  6. Henk Koning says:

    Sensors on Fuertaventura and Lanzarote show increased activity. Is there anyone who can explain this, or is this weatherrelated.
