Sunday 24th, March 2013Volcano -
NEWS:
9.52 Clock - a ML2, 6 quake at 8:52 clock in just 3 km depth off the west coast and at 9.40 clock a ML3, 2 earthquake at 15 km depth. After a turbulent day yesterday want, we first of all take stock. The epicenter has moved slightly to the west and south. It is now about 5 km off the west coast of El Hierro. Registered, 170 of which 15 quake and tremors over ML3, 0 The strongest earthquake brought it to ML3, 5 The output depth has changed only slightly and is in range of 12 to 16 kilometers. Some ML3, 0 earthquakes in the 12 km area of the earth's surface are likely the most advanced sector comers - mark - the roof of the magma chamber.


Let's take a left on the depth chart of the quake. The brown area in the west is the new quake surge and with the Magma area equated. On the western edge, the magma is most ascended (12 km). Here, however, seem hard rock layers to impede the further advancement. Now it is conceivable that they are towards the center of the chamber - direction Tanganasoga - vorarbeitet horizontally. The cathedral is sufficient for up to 5 km Sabinosa under the island's surface. The pressure inside the chamber must be immense. In recent days, GPS deformation values ​​were up to 4 inches measured vertically to the west and the Gulf stations. This data is up to date and never come out of the previous days. A further increase of the island surface is expected.


Since yesterday, the Ramon Margaleff is with a group of scientists back from the coast (thanks to Carlos) in action. It is a planned long research effort that is modified but certainly because of the current events. With its technical capabilities, the research vessel can in the West the sea floor (there more than 1000 m deep) scan and trace any changes. Not that another eruption is seen in the summer of 2012. remarkable still is the information policy of the island and the Gobierno de Canarias. No official announcement and no syllable in the local media. Now, however, likely to have been felt vibrations to the last house.


An open information policy we had made 2011 for the future. It reminds me now but more of a Schweigegelübte. For whom or what purpose is this good, it remains to be seen.

... and it continues unabated today. Already over 50 quake to ML3, 0 in the last hours. Everything is reminiscent of the volcano beginning in fall 2011. At that time the quake lay a little farther north under the Golfobecken. So we wait and watch further the workings of nature.

It was a short silence wakes up the volcano again. It is noticeable that the deep center has now been reduced. Was it in the last few days at 17 km, today tremors were also made ​​from 12 km depth . The magma is likely to rise further.




The epicenter is located as usual in front of the western tip of El Hierro. Where in June / July 2013, the first "undiscovered" eruption lies with today three underwater volcano. For a better classification I will this eruption site in the future as Eldiscreto II beszeichnen.

Comment by Jon Frimman.

''Please note that earthquake swarms start with an harmonic tremor pulse coming from El Hierro volcano. This means that magma is being injected at depth under heavy pressure. Currently there is an sill forming inside the volcano. If that sill is going to erupt there is no way to tell at the moment.

The ocean depth at the current location of the earthquake swarm is around 2 km to 2.5 km. So if there is an eruption it is not going to be observed on the surface on the ocean. Unless it reaches higher ground.

I am watching and writing about this on my blog as always.''

The Earth still trembling in El Hierro. Yesterday there were around 200 earthquakes of magnitudes of between 1.5 and 3.5 (lower were even more), several of which were felt by the population. According to data of the national geographical Institute (IGN) the largest earthquake occurred at midnight on the Friday to Saturday, with magnitude 3.5 and epicenter to the southwest of the punta de Orchilla. During the day yesterday, there were several larger than magnitude 3.

The depths in which these events are have been rising and even though at the beginning of the week, when it began this new batch of seismic events, all earthquakes were between 15 and 20 kilometers already yesterday some stood 11 kilometers deep and, generally, depths were lower that a few days ago. If data from seismographs are clear on the volcanic activity of the island, antennas GPS the volcanic Canary Islands Institute (Involcan) and IGN have also detected that the island continues to swell. With regard to gases, Involcan says on Facebook that have followed "the behavior of the diffuse emission of CO2 and H2S registered during the last months" through geochemical station HIE07 of ITER at the service of the Involcan.

In this sense, they report that before the recent period of anomalous seismic activity has been detected a relative increase in the diffuse emission of CO2, then and form simultaneously experience a relative decrease in the values of diffuse emission of CO2 and a relative increase in the values of diffuse emissions of H2S. "This geochemical behavior of these two volatile species supported a process of movement of magma beneath El Hierro", says the scientific institution.

This week the fifth episode of seismic crisis has lived since appeared in June 2011 a swarm of movements that resulted, in October of that year, at the start of the underwater eruption of La Restinga, which was completed in April.

- Believe it or not, but already 104 M2+ volcanic earthquakes below El Hierro so far today, that's 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.

We continue in the island of El Hierro excited as Marine geologists studying an active geological process, it is difficult to have the opportunity to investigate a submarine volcano in full development, and especially to see the reception that gave us the island whose seismic activity has been very large in yesterday and keeps us with the intrigue of being able to see how evolves volcanic activity in these days that we will be here.

After adjusting all underwater acoustic equipment, with which we are working on board b/o Ramón Margalef, have spent a night at full capacity. We were conducting a bathymetric mosaic of control volcano of La Restinga. So we have made two bathymetric surveys complementary probe multibeam, obtained at different speed to improve the density and therefore the resolution of the data. In addition have been attentive, and expectant, given the possibility to observe the emission of any plume of material from the basement using all available equipment: high-resolution seismic profiles, profiles of hydrographic probe and the module of the water column of the probe multibeam. In this sense we have located three possible points that acoustically can be explained as produced by emissions, which we interpret as possibly from gas, in the vicinity of the volcano in La Restinga, and who soon our fellow physical and chemical test stations of rosettes of bottles and CTD are already doing at the moment, to affirm or deny this character.

As something else, map of earthquakes in what we have to swarm from the night of the 17th, took 29 earthquakes of magnitude 3.0 or higher... the last 3.6 has been more northward, a little apart from the rest and indicates that tensions and pressures is are dissipating around the swarm, observing several alignments n-s.

Jon Frimaan has reported an eruption has started.

This is currently not confirmed by any authorities in Canary Islands, El Hierro Island. This view is only based on the data that I have access to and my experience in reading them. I might be wrong. But I do not think that I am. This information might and is going to change rapid in the next few hours!

Around 01:00 UTC on 25.03.2013 it seems that eruption started somewhere in El Hierro volcano. I am estimating that it started somewhere out in the sea. Since I am currently not seeing any reports yet that it has started on land so far. If that is the case, it might not be observed by people. But it might also reach land if this an fissure eruption. It is impossible to know at this stage.


Harmonic tremor as it looks normally on IGN web page. This plot has been scaled down by IGN already. Copyright of this image belongs to IGN.

This activity has been followed by several strong earthquakes in El Hierro volcano. Earthquakes that have had the magnitude 3.0 to 3.2 so far. Currently the location of this earthquakes is placed out in the ocean where the depth is around 2 km. So if that is where the eruption is taking place. Nothing is going to be seen on the surface at all during the period of this eruption. It is also impossible to know if this eruption is going to last for few hours, days or weeks. But it seems to have started for now. I do expect the possibility that more activity might follow soon. That means anything from next hours, days to weeks.

I urge people to follow there advice of there local government, police and emergency response teams in El Hierro Island if anything happens on land. Do not risk your self for this while current status is unknown. It is not worth it.

The islanders are reporting hearing rockfall.

En Sabinosa, después de una hora de rugidos, me he levantado de la cama con el último, que ha sido muy fuerte. Han sonado los muros, el suelo y los cristales. Al asomarme a la calle, he visto a todos mis vecinos en puertas y ventanas y hemos oído como caían piedras por dos lados diferentes del risco. Así que aquí estoy otra vez.In Sabinosa,

after an hour of roars, I woke up in bed with the latter, which has been very strong. They have sounded the walls, flooring and crystals. I look to the street, I have seen all my neighbors in Windows and doors and we have heard as falling stones on two different from the cliff sides. So here I am again


En Frontera no para de la 1:09. El ruído es bastante fuerte y duran bastante... Es imposible conciliar el sueño y estamos empezando a preocuparnos bastante, esto no nos gusta.

In border not for 1:09. The noise is strong enough and long enough... It is impossible to fall asleep and we are beginning to worry enough, don't like us.

Eruption seems to be over in El Hierro volcano for now

Posted on March 25, 2013 by Jón Frímann   


Send to Kindle

The eruption in El Hierro volcano seem to be over for now. This eruption only lasted for about 2 hours. It is also an question if earlier episodes of this type where in fact eruptions. Not just harmonic tremors as I did first think. I am going to check that in next few days if I can. It is however important that this type of volcano activity can happen without much warning everywhere on the fissure in El Hierro volcano. As the volcano already has clear signs of from earlier eruptions in the past.

I am going to write more details on this after some sleep. It is going to appear sometimes after 12:00 UTC at the earliest.
