- We continue following eventual events on the island, but the last couple of weeks all activity calmed down. The last 5 days, we only could find 2 volcanic earthquakes below the island
Lijkt er op dat de activiteit nu echt wel voorblij is.quote:2012-11-26 17:56 UTC
- NO activity whatsoever since the last 2 days - this update especially for Suzanne who thinks that we are not following up El Hierro anymore )

- Rather lot of activity today (thank you ER reader Gos for informing us). In only 35 minutes various vcery weak volcanic earthquakes below the center of the island gradually shifting to the south. Depths like the latest swarm. The next 48 hours will indicate whether this was a unique event or wether a new episode will start.

- It is getting more and more interesting again (Thanks Goz for pushing us). One of the strongest earthquakes occurred on Thursday, a M2.6 which was felt by the islanders. This stronger earthquake indicated still the strength at the +20 km layer. The other earthquakes are occurring in the shallower 10 km depth zone, but these are weak to very weak. What happened the last couple of days has almost the same patters than during the last serious swarm episode (2 layers – the strongest ones at +20, the weaker ones at the 10 km level)

- Activity continues in the somewhat deeper 17 to 21 km layer in the same Las Puntas Frontera area. As the HT remains almost flat compared to the strong amplitude yesterday afternoon, it looks that the magma has been stopped at the current stage. Only earthquakes are generated. Next 24 hours will give us a clue whether the magma will remain locked in or will find a way to another point.
- The only point to the south of the swarm is a 10.6 km depth earthquake which you can see in the list. We do not think that there is a relation in between the swarm and the isolated 10.6 km quake.

When an undersea eruption began off the volcanic island of El Hierro in 2011, research ships showed up in the Canary Islands right away to study it. One thing they found in the first days was floating rocks of a peculiar kind, like a geological frybread or fritter. Now a paper in the open-access journal Solid Earth has given them a more scientific-sounding name: xeno-pumice.

Na mijn reply op Earthquake-report zijn ook daar de reports [1] [2] over de smoking lava bombs gezet.quote:Op woensdag 25 januari 2012 18:52 schreef Tokamak het volgende:
[..]
Het water is (althans een aantal dagen geleden) nauwelijks warmer op de plek waar het wit is. Dat zijn voornamelijk gasbubbels die opstijgen. Soms raken die gasbubbels gevangen in de lava, en in een zeldzaam geval ontstaan er zo hete brokken, gevuld met gas, die naar de oppervlakte stijgen. Die veroorzaken de rookpluimen die je soms ziet. Als er hele rookwolken ontstaan, net zoals gister het geval was, dan zijn dat heel veel van die brokken.
Hier een illustratie wat er gebeurt, En als je goed oplet tijdens de activiteit, zie je ook dat die brokken/de rook zich niet in de 'jacuzzi' bevinden, maar er net achter

- More action than usual the last couple of days (but far from a new episode of course)
quote:2013-01-25 22:57 UTC
- 3 volcanic earthquakes today.
- IGN has confirmed that the stain earlier this week was because of degassing of the volcano edifice. This phenomenon can go on for some more weeks.
- The President of the Canary Islands, Mr. Ricardo Melchior, has made a statement that Involcan will get the necessary 240.000 euro to continue their work.

- A strong (for El Hierro at least) earthquake occurred at 16:27 UTC at a depth of 15 km.
No other earthquakes have been listed by IGN today, but if we watch the HT graph, we see some real changes happening. We are of course curious what the next hours will happen. The HT line is seriously thicker than this morning and the amplitude increased a little before the strong earthquake. Location of the epicenter here. The epicenter of this quake (more or less at the new volcano buildup) makes this episode even more interesting.

- Superficially it looks like yesterdays activity ended, but if you look carefully at the CHIE graph, many micro events are still occurring.
- IGN has not listed (at the time of writing) the 02:33 earthquake yet. This was a local earthquake as no other event so strong happened elsewhere in the world.
Het lijkt rustig. Maar onder de grond gebeurd van alles - het rommelt best - maar op een zwak niveau. Het komt net boven de ruis uit. Is sinds de laatste beving aanwezig - van de 31e.twitter:teideano twitterde op zaterdag 02-02-2013 om 15:28:06 And the story goes on and on at El Hierro.....Up/Down shown here.... #volcano #geology http://t.co/ktUSjfS6 reageer retweet
