@ teideano Strong evidence of gaseous emissions, but the NS lineation detected (no rift W Control). Remember the plumes of IOE to N?

@ pabloj_gonzalez if those limits seemed linked to the sliding of the Gulf, there seemed to be more control structural aspects.

quote:Involcan confirms a new undersea volcanic activity occurred at El Hierro in 2012
The submarine volcanic activity occurred near the west coast of the island and was associated with seismic-deformational crisis in El Hierro recorded June 25 to July 9, 2012
Tenerife-05.02.2013. The results of a collaboration between scientists at the Volcanological Institute of the Canary Islands (Involcan), the Geological Survey of Spain (IGME) and the Hydrographic Institute of the Navy (IHHM) confirm that at the end of June 2012 there was a New undersea volcanic activity was not perceived and which has not been recorded so far.
The research of marine geophysics conducted by researchers and IHHM IGME aboard the oceanographic research vessel Hesperides, recorded last June 27, 2012 several emission plumes of volcanic material less than 2 miles along the coast west of El Hierro (volcano Lomo Black-Faro The Orchilla) at depths between 64 and 88 meters. These plumes were recorded through acoustic images which enabled the research team includes scientists from IGME, Involcan IHHM and identify the existence of volcanic material emitted from the seafloor and that came to form plumes that reached 48 meters .
This new submarine volcanic process was preceded by a series of warning signs. In HIE02 geochemical station, that has Involcan the western part of the island of Meridian, was an increase of radon activity from late April to early June 2012 getting itself to peak values 10 times higher than normal values for this season. Monitoring and measurement of isotopic ratios 3He/4He in helium dissolved in groundwater San Simón hole, located in the eastern part of the island, accused the highest emission of helium-3 recorded since the start of the recovery magma of El Hierro. Besides these geochemical precursory signals recorded a sharp increase of the seismic energy released and the number of earthquakes of magnitude above 2.5 as of June 25, 2012. Alongside the GPS Network stations Canaria (Involcan-GRAFCAN Nagoya University) measured very significant shifts in both the vertical and the horizontal, accusing elevations of about 3 centimeters during the first two days of the crisis of seismic-strain June 25 to July 9, 2012.
The cooperation between scientists from the aforementioned institutions has identified a new undersea volcanic activity on El Hierro in 2012 of great scientific importance to assess the current magmatic reactivation process under the Meridian Island, and for the purposes of prevention, but fortunately it had no impact on the security of the population. The results of this work have been accepted scientific cooperation to be presented at the next international conference of the European Geosciences Union to be held in Vienna (Austria) from 7 to 12 April 2013.

- We were disturbed in the middle of writing an update for El Hierro when the Santa Cruz Island Mega-Quake hit.
- 3 Spanish organisations (Involcan, IGME and IHHM) will publish a scientific paper at a conference in April claiming that they have found another eruption location at the south-west part of the island. The eruption was detected by the oceanographic vessel Hesperides during the fierce seismic period of the end of June / beginning July. Sonar images show, what the researchers are claiming to be volcanic plumes, eruption material released at less than 2 NM from the coast and at depths of 64 to 88 meter. The released material was thrown up to a depth of 48 meter. Involcan sees a confirmation in their findings from the strong deformation at the time and from some increased chemical values. (ER:Involcan omits one of the most important elements here : the depth of the hypocenters! There were almost no volcanic earthquakes at a this shallow depth, neither was there any evolution in shallower depth – read our extensive reporting at the time here))
Involcan got its moment of glory explaining this “new” event on all Spanish TV stations. Big news in Spain.
- For ER the big news is that these scientific organizations did wait 6 months to disclose these findings. These acoustic images were almost IMMEDIATELY available at the time the Hesperides made his research trip. NO WORD TO THE PUBLIC at that time. Since the beginning of the El Hierro eruption process, our readers have the feeling that the Spanish research institutions are not publishing all they know. The current disclosure is another proof of all this. We do not think Involcan is to be blamed for what happened (or did they wait to present their scientific paper on the conference), but other organizations surely are.

- The image below shows a new (short) period with volcanic earthquakes. The strong tremor at the start tells us that the magma reached other channels. The hypocenter depth remained however in the 16 to 18 km layer.
- The 3th map shows the deformation of the island and as could be expected with such a crisis, the activity is also confirmed in the deformation which is a mainly eastern and upwards (center and right parts of the graph)
- Another map shows the location of the epicenters of todays earthquakes. No real change vs yesterday and 2 days ago.

Als ik kijk naar het stukje van 2013-03-24 13:24 , lees ik de conclusie dat een eruptie boven het bevings gebied zou moeten komen.quote:2013-03-24 13:24 UTC
- Believe it or not, but already 104 M2+ volcanic earthquakes below El Hierro so far today, thats more activity than yesterday at this time of the day. Yesterday ended with 165 volcanic earthquakes.
- Hypocenters in the 15 to 17 km layer
- When pinting the center of the current action (last 15 earthquakes) on a Google earth map, we arrive at a seabed depth of 1800 meters
2013-03-24 08:48 UTC
- Our daily M2.5 earthquake list looks like only the Canary Islands exist today.
- The scientists who said a couple of days ago that this crisis wont end in an eruption as the strength was not enough to reach the seabed, may start to write a second opinion. The crisis goes on and is a lot stronger than the last episode. Some more facts :
- 62 M2+ earthquakes so far today = hundreds of volcanic earthquakes of we would also count the weaker ones (which IGN did at the start in 2011)
- Hypocenter or focal depths (breaking point in the layers below the island) 16 to 17 km depth (4 to 5 km deeper than yesterday).
- The epicenter locations have shifted a little to the West (main reason for the deeper hypocenters).
- Deformation statistics are very spectacular as the Sabinosa GPS has been forced upwards with 2 cm the last 24 hours (see image University of Nagoya below ). The same GPS was also forced 1 cm to the East. North/South remained the same.
quote:2013-03-23 19:15 UTC
- 134 earthquakes so far today (strongest activity since the start of this seismic crisis)
- Hypocenters gradually shallower (12 to 14 km layer) which indicates that the magma is reaching cracks in higher levels. Too far out in the sea to generate a Surtseyan eruption if a new vent would emerge (seabed depth 1000 to 1300 m)

Als ik kijk naar het stukje van 2013-03-24 13:24 , lees ik de conclusie dat een eruptie boven het bevings gebied zou moeten komen.
Als ik kijk naar de eerste eruptie site, van La Restinga, dan zaten de bevingen grotendeels onder het eiland en zeldzaam ronde de plek van de eruptie.
De recentelijk genoemde 2e eruptie plek daar in tegen zat wel in de buurt van de west kust. De bij behorende bevingen zaten iets te noord westen van de eruptie plek.
Als je gaat kijken naar het genoemde centrum van de huidige bevingen, zee bodem zit daar op 1800 meter, dan zou een eruptie mogelijk een eindje verder naar het zuiden (en ietsie oostelijker) te voorschijn komen.
Dit zal dan nog altijd verder westelijk zijn dan de laatste eruptie. En dat is dan ook gelijk weer een heel stuk dieper. En waarschijnlijk zullen we daar niets van gaan zien door de diepte.
En daar schreef EarthQuake Report ook al over

Luckily for El Hierro everything is happening out in the sea at a depth of +1500 meter. A volcano has however NO guarantee at all that the action will stay in that area. The same happened during the eruption in 2011 when the magma vent was located in a totally different area than the earthquake epicenters. This was however an exception.
