Update 29/03 – 21:20 UTC
 - The BIO (Buque de Investigación Oceanográfica) has made a short bathymetry mission stop at El Hierro today during his return trip from Antarctica. Spain has an Antarctica base and during the months November to February, the Antarctic peninsula is merely ice free.


Update 29/03 – 21:04 UTC
 - The Spanish Army is really good in public relations. IGN needs to take an example on them. In a press report on the Armada Española website this evening, the bathymetry mission was highlighted.
 "El buque ha realizado varias líneas de prospección en una cuadrícula de trabajo situada en las coordenadas: 27º 40´N // 27º 30´N de latitud y 18º 05´W // 17º 55´W de longitud, para determinar el punto de mayor altura del edificio volcánico y comprobar posibles variaciones desde el último levantamiento batimétrico."
 Human translation : The vessel has done several rectangle routes under the coordinates : 27º 40´N // 27º 30´N de latitude y 18º 05´W // 17º 55´W longitude to determine the highest point of the volcano and check any possible changes since last bathymetry.

Earthquake-report.com are commenting that it is interesting that a day after the Spanish Army ship made a new bathymetric of the cone another ship was on the stain the next day but measuring what?

ER comment : nothing new here of course, at least nothing which surprises us. The jacuzzis we have seen for many days in a row are absolute signs of further degassing.  The main question remains, is there still lava coming out of the vent. The last time we know for sure that that was the case was on March 14 when the ULPGC ROV made a video recording of it.  The latest bathymetry data from CSIC did tell us that the cone was at 88 meter. But this depth was measured at the end of February ! All frequent El Hierro eruption followers have 1 major question. How deep is the crater rim at this moment ?  Is it a coincidence that the Salvamar Adhara starts filming again 1 day after that the  BIO Hesperides measured the depth of the Las Calmas sea floor or cone ?

Good video jand. Some recent articles say that the degassing is normal and are sticking to their opinion that the volcano is dead. I have my doubts and am still waiting for the Rooster tails.[]

[jand]

Hi Fifi Joke did see a colour on the stain and it was mentioned degassing does not cause colour change the erruption ongoing would cause colour changes in the sea.

Intereasting to see aswell the earthquakes are changing direction .

Its just a waiting game again .

Avcan comments re the lastest earthquakes.

On the map of seismicity of recent days, today we have a small one in the mar de las Calmas and three yesterday, two in the mar de las Calmas and another near the Gulf Coast. Antesdeayer there was one in the mar de las Calmas and then we have two to the West of the island in the sea of the day 29. These earthquakes at sea with other earthquakes of other days forming a fourth ENE-OSO alignment. The earthquakes of previous days, are aligned according to three principal axes NNE-SSW that is very well appreciated NNW-SSE with fewer points and gave both to speak and one these last days in ONO - that address that cuts across the island (Henry).

Comments on Avcan facebook page yesterday were saying the stain was growing there were three earthquakes yesterday two over 1.5mg and the third one was a 2.7mg which was in the area of Bob and was felt on the island.

Someone on Avcan Facebook commented this was felt also in La Palma?

Good morning, follow the meneitos, for a change, a 2.5 in the area of the pinewood where yesterday had 2.7 who has been able to be felt by the herreña population. If what you have sense to remember to fill the questionnaire of the IGN, is very important (Henry)

Update 03/04 – 11:49 UTC
 - a lot of microseismicity today, we expect a couple more 'measurable" earthquakes later today (microseismicity is not listed as the quakes are too weak and/or the epicenter location cannot be determined)à
 - Joke wrote to Mara-Jose Jurado to congratulate her with the  video recording (see below). José-Maria told her that it was the first time that the water was clear enough to result in good quality video. She also said that the Camera was made in Spain and thet CSIC-IGN was cooperating with the camera company to test it further. She also said that they had more interesting video, and that they will certainly release it after re-editing.
 - One of the quake epicenters was located at the western corner of the Island (see map elow). Joke told us that the area has a huge crater which was formed after a hydromagmatic historic eruption. On March 18 she has visited the area as part of one of the volcano courses she has been following.

Update 03/04 – 08:01 UTC
 Is this a sign of the awakening of the volcano ? To early to tell, but what we have seen so far today is the renewed activity of the feeder area at El Golfo. 3 of the 4 earthquake epicenters are located in the El Golfo area. The strongest M2.5 quake below the (new) volcano-vent itself.

Update 05/04 – 13:09 UTC
 - The earth is still shaking below the island. 2 new earthquakes ! IGN will have to stay a little longer.
 One at 06:31 at a depth of 19 km with a magnitude of 1.5  Here
 One at 08:00 at a depth of 12 km with a magnitude of 1.0 Here

Update 05/04 – 07:22 UTC
 - NO earthquakes since the day before yesterday

Avcan Facebook comment.

Note 500 AVCAN - earthquake activity - VOLCANIC - island of HIERRO - 05 April 2012-10: 15 pm peninsular - earthquake and volcanic activity continues low to very low, today without localized seismicity at the moment, although still see something of microsismicidad detected but not located in the spectrogram of the sensor of CHIE (and some clearer at 06 sismito; 32 UTC). The signal of volcanic tremor in the eruptive area of la Restinga has disappeared or is so low that not located it instruments and cannot be taken for extingido, having reached zero Toolkit. New earthquakes 0. 4 The day before yesterday. Yesterday 0. Today will be 0. In total van 12565 earthquakes located in El Hierro by IGN from 9: 00 a.m. of the day 19 July 2011. On the map the seismicity of this year 2012 in red (605), over that of the previous year 2011 in yellow (11952) and the earthquakes of 4.0 or greater in purple (5) (Enrique).

Update 06/04 – 08:13 UTC
 - NO earthquakes since midnight
 - The (horizontal) deformation of the island remains almost unchanged. Some scientists think that the volcano may keep his inflated position for a much longer time. Unfortunately IGN does not publish the vertical deformation.  This kind of "selective" publishing feeds the "conspiracy" followers.  They think that if you hide some information, you are trying to fool public opinion.
 - Carmen Romero Ruiz, a researcher specialized in volcanic geomorphology at the University of La Laguna, has found evidence of many El Hierro eruptions during the last  centuries.  Some signs are pointing to 2 eruptions in the 17th century and even more in pre-hispanic times. She also said that a submarine eruption has occurred in 1793 . Interesting to know also is that the island of La Palma has had approx. 20 eruptive periods the last 2500 year.
 - The Cornide De Saavedra is still navigating along the La Restinga coast. Results however seem to be TOP SECRET as we haven't seen any results from the BIO Hesperides neither.

Update 08/04 – 11:55 UTC
 - Joke Volta reports she saw a jacuzzi this morning. Also, in the past the days it has become increasingly difficult to distinguish the jacuzzi from strong currents at Las Calmas sea. She has taken photographs which will be online later today.
 - First earthquake of the day: 10:09 UTC M 0.7 SW El Pinar.


--------------------------------------------------------------------------------

Update 07/04 – 18:10 UTC
 - NO earthquakes since a couple of days (bad news for activity lovers)
 - The bathymetry results of the BIO Hesperides from approx. 1 week ago (Polar Oceanographic research vessel) are indicating NO change of the cone depth. (source : Diario de Avisos)
 - The ministry of health of the Canary Islands has a website which indicates whether it is safe to swim at some beaches. At El Hierro, some beaches like Tacoron and the lighthouse are seemingly "forgotten" says Joke.
 - The video below has been published by INVOLCAN in cooperation with the Guardia Civil Helicopter unit (yes, the people responsible for almost all El Hierro helicopter footage). The 15 minute video shows beautiful images of the overflight of the still active Pico del Teide, Tenerife's sky high beautiful volcano.

Update 11/04 – 08:28 UTC
 - 1 Magnitude 1.1 earthquake at a depth of 20 km to the SW of El Pinar (approx. 10 km from La Restinga !)
 - An AVCAN commenter mentioned a link to a very interesting document on Volcano lave tubes speleology at El Hierro. Click here to consult the document, but in case you are going to use it, please be careful !
 - A group of Senators from the Spanish parliament  (1 per fraction) will make an incentive tour to El Hierro, next Thursday. If weather and conditions are allowing it, the visiting group may make a boat tour to the volcano vent. Senators and a volcano, an explosive cocktail ?

OT there has been an 8.6mg earthquake near Sumatra this morning.

They are still having earthquakes in the area some every five minutes.

OT but ETNA is errupting again live webcam link shown below.

Update 12/04 – 14:06 UTC
 - ETNA (Italy) is currently having a new paroxysm or eruption (thank you Er reader Roland for informing us). Click here for our Volcano News page with links to the best webcams.  Julio del Castillo Vivero made a time lapse of today's Etna eruption. Enjoy the beauty of nature.

Update 12/04 – 09:22 UTC
 - Joke reports that a stain has been seen in the Las Calmas sea. She is talking about a short reactivation of the volcano yesterday afternoon. Joke says that the stain was confirmed by the IGN people. In a first reaction Roman Ortiz has related the stain to the Sumatra earthquake ...
 - From our side, following with large in-depth articles on every world quake, we are stressing that the increase of the amplitudes in the CHIE graph are all of them related to very strong to massive earthquakes in different parts of the world. (Mexico x3 + Sumatra). Scientists do not agree on a direct relation in between earthquakes (even very powerful earthquakes) and volcano activity.
 - A ship is currently executing a bathymetry mission in front of the La Restinga coast. Julio del Castillo Vivero  reports that it will be probably the Oceanographic ship Las Palmas (A52)

Lets hope the Senator from Madrid listens to Joke about reconnecting the webcam.

pdate 13/04 – 14:20 UTC
 - High visit at La Restinga this morning.  Senators (Spanish parliament Madrid) have been informed about the El Hierro eruption. IGN and CSIC scientists have given explanatory sessions on the activity. As promised earlier today, Joke could profit from a few free moments from a senator and asked him to support the call of the International Community to get the webcams back. Whenever this Senator (we know his name) would be able to bring our webcam back, we will print a huge image in this site thanking him for his support to the good cause !
