El Hierro

[jand]

The Avcan Facebook page is a good page to follow as the comments are up to date and sometimes minute by minute from people from El Hierro and also Tenerife and Gran Canaria .

Some of the  islanders on El Hierro are posting facts as they happen and it is interesting to follow if you are interested in whats happening at the moment.

The comments are in Spanish but can easily be translated by Google/Bing free translation.

Avcan are also updating graphs maps etc which again are interesting to look at.

Update 15/09 – 16:12 UTC
- 110 earthquakes. Depth 20 to 22 km. All of the epicenters (last 10) below the historic main crater. It looks like the magma has settled below the current area (no thick lines on the CHIE graph)

Update 15/09 – 13:57 UTC
- just received an Email stating that a M3.2 struck at El Hierro on 13:13. Epicenter, just north of El Pinar. This earthquakes was generated at a depth of 24 km some 2 km north of El Pinar . It was felt by the people.
- Today's total has reached 97 earthquakes

,,Yet yesterday morning, I spoke of a "model" as the volcano activity further could develop. A few hours later it was already a reality. Trigger was a tremor of ML2 2 at 10.10 am 20 km deep under the Gulf (see graph left). Followed by a quake burst as we it knew only from the beginning of the volcanic activity exactly a year ago. Set against noon then countless micro earthquake - the so-called tremor (wavy lines picture) a. Everything takes place in great depth of 19 to 23 km in the area of the main Chamber of magma. At the time should Chamber to flow in large quantities of fresh magma from even deeper layers of the Earth in the.Center point remains the old volcano mountain Tanganasoga on the Abruchkante to the Gulf. In the course of the night the quake have worked before further to the South (red dots). The foremost earthquake tips separate only 1 to 2 kilometres from the old eruption site of Eldiscreto in the South. We know from the experience of the past, how quickly the magma from can become 15 km of the Earth or sea surface. 23.39 At, there was already a tremor with ML3, 1. And this magnitude will continue to grow. You have to be a Prophet for the weekend Quake with ML4, to include 0. Then there is extreme landslide and Steinschlaggefahr especially for the steep slopes of the Golfotal! This is the real danger at the moment.,,

Avcan are reporting there have been movements and EQ'S reported on other islands.

..Also there have been reports of some earthquakes, as well as noise and vibrations from other islands, specifically from la Palma, La Gomera and Tenerife..

The island is inflating again as  expected by the movement of magma and yet no official response to the new actvity at all.

Update 16/09 – 07:46 UTC
- Until 07:35 today, IGN has listed 73 earthquakes. Magnitudes vary from M1.4 (the weakest they are listing but there are hundreds more below this Magnitude) to M2.7. Maximum magnitude decreased a little bit from yesterday (up to M3.2).
- Focal depth remains the same (no penetration into shallower layers)
- Epicenter location is fairly stable (see image below and compare it to the last images yesterday)
- NO more (listed) earthquakes in the El Golfo bay at the 10 km depth layer.
- In line with what could be expected is that the deformations are up again.
- Frontera GPS station has moved North for about 1.5 cm and was also lifted with about 2 cm.
- El Pinar GPS station showed the same movement.
- Restinga GPS station moved a little eastward, did not move along his latitude axis and was inflated most of these 3 stations.
All these data were Ultra Rapid data coming from Prof. Sagiya, a GPS authority in Japan working at the University of Nagoya.
All the mentioned stations operate automatically, which means that nu human is needed to send the data to the computers of the University. Check PINA, FRON and REST stations here.

Top left the Golfotal with La Frontera. The dashed area is about 1000 meters high cliff and about the district boundary between La Frontera and El Pinar (right). Under this green plateau (Pine Forest) with + + + located in the epicenter. There are only a few hundred meters to the Abruchkante Tanganasoga - and that makes things for rockfall and landslide hazard.
Yesterday we had about 13.13 clock in this area as the strongest quake one ML3, 2 earthquake   . within 24 km depth

Hi Triple H El Hierro is still surprising us all when you think its going to be all over the fourth fase a new intrusion of magma starts.

Update 17/09 – 17:05 UTC
- 84 earthquakes until 16:11 UTC
- Another 2 shallow quakes at 10 and 11 km , both in the El Golfo, Sabinosa area. The phenomena described in the last update is being confirmed with these quakes. The Sabinosa – El Golfo area has become active again. We are however unsure whether IGN has deliberately omitted the quakes in this area when the strong swarm started. If this was not the case (what we should find very normal) then we can speak of a changing pattern. The following hours will give a better idea of the situation


Image courtesy Avcan

Update 17/09 – 15:36 UTC
- Is the crust starting to show cracks ? Why are we writing this ? If IGN data are correct, we have noticed a number of shallower earthquakes the last couple of hours. Nothing to be scared off, but this is definitely a change in patterns versus earlier today and the 2 preceding days.  From 12:27 until 14:39 (less than 3 hours) we have noticed 6 under 20 km earthquakes on a total of 17.
The shallowest being a 13 km, but also a 15 km and a couple of 18 km. Is the magma the cause ? IGN would probably know it but mostly keeps his information for international science conferences a couple of months later!
The shallowest one was recorded below the Sabinosa area, the area where the other 10 km were recorded last week.
- 71 earthquakes so far

Update 17/09 – 12:45 UTC
- 52 earthquakes so far (listed by IGN until 11:06 UTC). No change in depth patterns or epicenter area. I looks more and more that the island consists of solid rock where magma has a hard time to penetrate

- Pevolca maintains the "Green Pre-Alert" status
- Joke has told us that the Spanish government does not want to finance the additional Involcan operations anymore. For this reason Involcan cannot continue some samplings at El Hierro and refuses to send additional scientists to the island.
The main reason for this attitude is that the Spanish government is continuously searching for spending cuts in order to comply with EU rules. Spain has a serious banking crisis generated by a real estate bubble, similar to the one who triggered the crisis in the USA (and later in the entire world) in 2008.

Here we go again

- 14 more earthquakes since our latest update and to our surprise a lot of single digit depths.
- One of these quakes was at a depth of 3 km but this quake may have been generated by deformation stress as no other quakes were triggered in the same layer.
- A lot of these quakes were weak volcanic earthquakes
- These new events will hardly have been felt by local people because of the combination Magnitude / depth, but must be certainly worrisome for those living in the El Golfo area.
- We truly hope that the analysis Involcan reported to have stopped have been picked up by IGN as people in the area should be informed in-depth of what is happening. In a normal volcanic environment, the potential eruption area is very well known, but in El Hierro's case, only the follow up of seismicity, deformation and sampling will lead to the prediction of  an eruption spot.
- We are sure that the IGN volcanologists are following up the events continuously as the past events (swarms from June and last week) have proofed that events can start in a couple of hours and reach high numbers of quakes in less than 24 hours.

A word from Joke Volta, yes still living on the island and worried even more than before :


Hello everybody...this must be the longest volcano reporting of the world...
For instance last week, activity was coming up, and reaching levels of about 200 quakes a day (198 te be exact)
A very short period, and a lot of quakes, if you compare it to what happened in June this year.
I was really worried, but the situation is still the same, go on with watching because yesterday's swarm in the Golfo-bay-area was shallow again (other active spot). Let's not forget the deformation, must be hugh forces, to lift up the island this way...
So...we go on reporting, wishing you all a nice weekend.
Be patient ... geological procedures can be last a long time ...

09-22 20:52 UTC

- 3 more earthquakes this afternoon
- we have the impression that the magma in the El Golfo area has found some cracks to infiltrate in the 7 to 8 km depth layers. Last week, only sporadic earthquakes were noticed at less than 10 km.

09-22 17:10 UTC

+ 2 more earthquakes, the first being a M1.6 and the second a M1.0 both at a depth of 21 km



2012-09-22 11:04 UTC

- 3 new earthquakes in mixed depth layers as you can see below.
- the last 10 epicenters are showing a mixed picture
- we do see again some earthquakes in the southern part of the island and in the Las Calmas sea. These earthquakes are situated in the 18 to 22 km depth zone
- for those people only following this site recently : last years eruption (colouring of the water, poisonous magma, floating lava, etc (see our first 30 parts below) was approx.. at the southernmost epicenter

- 4 volcanic earthquakes since midnight, all of them below the center of the island in the deeper layers
-  the strength of the center island quakes is generally stronger than the El Golfo quakes, this because the main source of magma is located in this area (last swarm in this area generated quakes until M3.2)
- GPS Deformations : PINA and REST have taken a day off today. FRON decided to continue working and showed a deflation of 6 mm and a movement of a few mm to the south.

This as recently been posted by the Manfred the German who lives on El Hierro and is writing his own blog.

,,Also, there are reports of deformations of doors and Windows which are no longer suggest, and the smell to rotten eggs in the Golfotal. No presumption, but eyewitness accounts currently be read at Avcan.Despite the declining quake, the island further deform in the height. After the latest GPS deformation has increased readings of Nagoya of University in collaboration with Involcan (Instituto Volcanologico de Canarias) since 13 September 2012 in La restinga 4.81 cm in height. While the island has moved horizontally southeastward to more 1.34 cm. Overall, the vertical bump is now at approximately 10 cm above the normal value. For El Hierro a unique value - worldwide however deformations were measured up to several meters. These facts are also and can be read at Involcan. On the reasons and suspected causes I had left out already me in recent days.Hierro - island of fear. No "subliminal" comment but the title of yesterday evening in 3sat broadcast film. No ad on this beautiful island. A psychological thriller which was partially filmed in the Golfotal and ver Odal. Creepy night and more beautiful nude photographs in Banenplantagen and one in El Hierro shot so non-existent campsite. He would have somewhere else also occur in the world. Unfortunately, he is named "Hierro" but and was also still financially supported. You must have not seen this movie.The nerves on the island are "blank", one can understand. I know and accept also some hypersensitivity. But here, too, there are limits. Any readers and visitors can decide as he was as the facts and figures and also my "subliminal" - it means, to classify conclusions has. If he decides to postpone his visit now, or to cancel, he sure has his reasons.I wear together only the information, match it, and level one after my logical expertise.If I warn against "Steinschlaggefahr" when a strong Quake in the Golfotal, I have my reasons. I know well the drop-offs and the situation on the ground and the threats it posed. Everything else is hypocrisy and belittling the situation.Not more and not less - I see that as my job - and this is appreciated. Not in vain 6-7,000 visitors visit this blog - and that at the moment daily total - page views are the last 13 months right up to read.Too many mails which daily reach me, encourage me.I do not admit also, that lump sum be stamped the readers as voyeurs, alarmists, Sensationgierige or conspiracy theorists. It is a human basic need to be something "curious" and to view what is happening in the world outside the box. The new media like the Internet make it possible.Also I would ask not to forget that in addition to the volcano had many other issues such as the "alternative energy project Gorona" in detail - presented to be noted that only on the edgeThere is no compulsion to visit this blog. There are still others - even State sources with less "subliminal" information. Everyone can decide what he reads and how he evaluates information for themselves as empowered citizens themselves.That done this topic for me.,,

,,There were no big moves the past 24 hours. Yesterday a total of 11 more quakes (IGN map above), both El Pinar and Sabinosa in the Gulf. This morning at 4.17 am a ML2, 3 tremor in 21 km deep in the coastal area of El Julan (left) on the Southwest flank. Unconfirmed reports or better rumors that yesterday afternoon from 14.30 to 16.30 unusual phenomena were observed are circulating. A white frothy bubbling "source" in the sea area west of Sabinosa. She reportedly similar to outgassing comparable to the previous Eldiscreto. Have subsided but without water discoloration and after about 2 hours and be gone again. I can not tell what is on this message off. However I had itself-greenish discoloration watch can already in this area in July and reported at the time.,,

,,Not Juan Ramon, it wasn't an inert foam displaced by sea spot. It was a bubbling alive, focused and with energy pulses, so many people became alarmed and believed that it could be a volcanic emission. It did not come from Sabinosa, because the current marina was going in the opposite direction. And if the Canary Islands Government recognizes that there have been discharges not authorized yesterday in the sea from the border, one in Sabinosa area and another in the area of Los Roques of Salmor, it is clear that what we saw was a spill...,,
