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.

2 new earthquakes with only 1 minute difference. The strongest one west of the island but gradually the picenters are heading north.

2 new earthquakes off the South Western coast of El Hierro. Both at a depth of 33 km (same depth as most of the previous quakes in that area)

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.

2015-12-04 19:37 UTC
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.

A new one today but again at a depth of 30 km. M3.0 is relatively strong

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.

2015-11-25 13:14 UTC
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.

2015-11-21 09:08 UTC
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.

Nothing spectacular the last couple of weeks. If a sudden revival would happen we will jump in with a new information stream of course.

It's about time to report the earthquakes of the last couple of weeks (Sorry Susanna). Here is the list of the preceding weeks.

Only 2 El Hierro earthquakes since our last update, but that does not mean anything of course :)

    I have not been able to reach the El Hierro pages on the IGN site but I can get http://www.ign.es without any problems.

  2. Mafl says:

    Here is a report of a possible new stain at the point of the 1-km-Earthquake:
    http://elhierro1.blogspot.de/
    Perhaps Joke can take a look at this place, because M. Betzwieser is not longer at El Hierro.

    • Armand Vervaeck says:

      Thanks Mafl. Joke lives at the opposite site of the islands and has unfortunately no car. She has a friend however in the El Golfo part of the island.

  3. brettio says:

    Joke mentioned the shivering earthquakes. As a child in NZ with Ruapehu erupting.. there were 2 types of earthquakes we felt in Taupo. first was a kerclunk jolt (quite strong)which was followed by a large volcanic cloud. and the second was a kind of tickling grinding(weak but lasting up to 30seconds.... which was followed by lava flows. I would take the shivering feeling as a serious observation that magma could be on the move...a laymans perspective and from experience.

    Hello Armand,
    Een uitgebreid wetenschappelijk artikel op de AVCAN site (hoofdzakelijk in het Spaans) van de onderwater vulkaanuitbarsting bij LA RESTIGNA van oktober 2011 tot maart 2012. Dit artikel is van ondermeer Perez-Torrada van GEOVOL.

  5. Benjamín says:

    Armand,

    Avcan reports on facebook about a 3.4 earthquake sw of frontera with a dept of 20,5km. The ppl on hierro felt it

    • Armand Vervaeck says:

      Thanks Benjamin. I was writing the update while your comment arrived, but thanks for telling me.

  6. BerryTh says:

    Has anyone else noticed the HT being higher than 2 days ago?

  7. Peter van der Woude says:

    "Yesterday we wrote about the (very) late info from the Helium-3 detection prior to the June 24 earthquake swarm. The reason for involcan publishing this info now is they didn’t have the results until a few days a go"

    And there is not a single spectrometer in Spain to analize gasses.... hard to believe

    • Julio says:

      There might be one in Europe, but from what I understand there is also a collaboration between a University in Japan and so they use theirs.
