Just read your posts on El Hierro. We are due to visit in September,will we be safe do you think and is there any precautions we should take. Many thanks

[Florence]

The precaution you need to take is not to read this thread and then you will have a lovely time.  El Hierro is just rumbling at the moment, and even if there was an eruption (which is unlikely) it will not effect Fuerteventura.

[Ronnietheblue]

Thanks so much for that, it does sound awful though, Jand obviously puts a lot of time and effort in.

El Hierro has been quietish all week although there have been shallow earthquakes.
Avcan facebook page is good to read as the comments on there are from the islanders themselves not just from El Hierro but from Gran Canaria and Tenerife.

.
,,Update 25/08 – 09:24 UTC
- A lot of action so far today. On top of 2 earthquakes to the west of Tenerife, El Hierro showed also a lot of activity including a very shallow one.
- There must be something wrong with Prof. Sagiya's GPS stations as the graphs are empty today. These graphs are automatically loaded by the GPS data provider. If the problems persist, we will alert the University.,,

RonnietheRhino I just try and report whats happening at the moment in and around El Hierro I am not a specialist I have been following this since last year and it is so  fascinating to read and learn so much about whats happening at the moment. I try and post maps and graphs so people can follow links to find out more info if they want.What the outcome will be if anything is in the hands of mother nature.

This is a comment from someone on the Avcan Facebook Page this evening . Translated.

,,
Good afternoon, without the latter 2.9, seems to me that the authorities are somewhat relaxed for my taste sismovolcanica current in the iron activity. Since the end of the series of major earthquakes in the month of July, has been quite reduced activity, but at this time it found as earthquakes were increasingly shallow, very little by little and releasing little energy, it has made them lower the traffic light and at the same time the guard, with this last swarm at more shallow depths is proving what I saythe magma much squeezed the first fifteen days, until somehow it has been finding the easiest way towards the surface, looks much better this week, which has managed to raise almost 2 Km away without barely strong earthquakes, demonstrating that when it does not progress and stagnates needed release more energy and when you release less is when progressing without much opposition. Hence this current phenomenon can be somewhat treacherous by stealth of his behavior, as AVCAN says in this post. ,,

This has been recently posted by a Spaniard on the Avcan FB page.

,,I'll be very blunt, and look to live quite far from the Canaries: It is normal in more than 15,000 earthquakes a year? is normal in the latter has risen la.profundidad swarm of earthquakes over 2kms in few days?? It is normal for an earthquake of considerable magnitude only measure from a station or at most two, and are the furthest? And it is normal for the authorities, minimizing an opportunity like few happen in this country to dissect, not for security, which is paramount in a situation like that, if not science itself .. and better not go on because need three screens to express what I think of todo.esto .. But I add to complete, now I just saw the seismogram and normality would be that there was not one, single earthquake in hours or days rather, but .. in the last half hour, the spectrogram CHIE has detected about 10 sismitos, which have volcanic activity and much .. Greetings from Barcelona,,

At the moment there are 8 earthquakes showing from 14.10 up to 16:10 on IGN.

Many thanks Jand for your informative updates, although i don't understand a lot of the scientific jargon. cancelled our holiday in feb, staying in uk instead. Hope all will be ok when the quake happens

There has been a 2.4mg this morning on the east coast betweeen Fuerteventura and Lanzarote it looks as if its  from the middle of the split of the two islands to the east.

I hope that was a joke!  Gee - jand, now that things are quietening down on El Hierro, please reassure me that you don't intend to work for Canaries tourism!

There were at least 13 shallow earthquakes yesterday around the Tanganasoga area and Joke Volta who worked together with Armand from earthquake-report.com made this commented over on the Avcan Facebook page she asks are the authorities going to say something now.
.

,,En los faldas d la Tanganasoga.entre 9,4 y 10,2 de profundidad...pero ahora parece tranquila.después esta repunte...pero sí. vaya...a ver si los autoridades se abren la boca.

On the slopes the Tanganasoga.entre d 9.4 and 10.2 depth... but now seems quiet. After this rally... but yes. go... to see if the authorities will open the mouth. ,,

[jand]

Update 02/09 – 17:33 UTC
- 3 more earthquakes
- Joke tells us that people living in Sabinosa and in other parts of the El Golfo bay are complaining about strange smells. This goes onfor at least a couple of weeks. ITER and IGN are told to take samples regularly, but the biggest complaint from the population is that nobody tells anything. Those following the events from the beginning do know that this comes not as a surprise to us. Most of the shallow 9-11 km deep quakes are centering in the El Golfo and Sabinosa area.

[jand]

Whilst its been relatively quiet in El Hierro (although there have been constant microswarms happening) today has seen the strongest earthquakes in a while.

Update 14/09 – 15:55 UTC
- As reader Pascal noticed a little earlierf, a lot of micro-quakes can be seen on the CHIE graph. They are mostly not strong enough to get enough data to be listed (or, as some people say, IGN does not want to list them to avoid frightening the people).  Honestly, we do not know it.
- We guess that IGN is about 2 hours behind listing the earthquakes
- The activity can well be seen on the CHIE graph. Clean graphs the last days or weeks with only a spike now and then, but today a lot of (mostly small) vertical lines.

Update 14/09 – 15:15 UTC
- 5 more earthquakes which brings today's subtotal to 20!
- We have a totally new pattern right now as the stronger quakes are deeper, but instead of epicenters near the lighthouse and at the western tip of the island, all the epicenters are concentrated in the El Golfo bay (below land) or in the old crater area. This means that we have 2 layers of activity in the same area : a) the weaker shallower layer mostly in the bay and in the Sabinosa area and b) the stronger deeper layer in the same greater area but so far almost all below the island itself.

Update 14/09 – 13:00 UTC
- 13 more earthquakes in a very short time, but this time with mixed depths (some around 10 km, others 18 to 20 km)
- Some people are referring to a stronger tremor signal but we cannot confirm this. The stronger quake action can be seen at the CHIE graph

[jand]

Update 14/09 – 19:41 UTC
- another set of earthquakes happened at 19:34 UTC, we expect in the M1.8 range

Update 14/09 – 19:33 UTC
- HT has subsided again. We expect more earthquakes later today as we seem to have reached a new uprise in action.
- GPS data tomorrow will tell us whether this was a short-lived action or whether more is expected
- The local press (like Diario El Hierro, Canarias7) just reports increased seismicity today
- We will keep looking at it for the rest of the evening

Update 14/09 – 18:49 UTC
- Some limited harmonic tremor shows in the El Hierro graphs. The tremor might indicate that magma is on the move below the island. To the positive site, we have to stress that all the earthquakes which are listed below (and thus happened before the tremor) are in the 17 to 19 km depth range. Only one at 10 km = no immediate danger based on the listed earthquakes.
- We hope that IGN will give the people of El Hierro enough information to understand what currently is happening

Note 100 AVCAN - 14/09/2012 - 23: 59 h peninsular. -DEVELOPMENT AND MONITORING OF THE SWARM VOLCANIC EARTHQUAKE ON THE ISLAND OF EL HIERRO. 100 notes from June 24, earthquake and volcanic monitoring eb El Hierro and just today arreon we have located more than 40 earthquakes and hundreds without locating, come with a revival in any rule of the volcanic system that makes it to be again present in the Canary Islands, and in several places, not only in one volcanic, today we see more clearlyTWO SWARMS earthquake-volcanic iron mismatched or in depth or in position... The first in the Gulf to Sabinosa area to about 8-11 km deep, and the second also in the Gulf, but under border - the Llanillos, area to more depth about 18-21 km. Seeing hundreds of earthquakes detected in CHIE and the few located in the seismogram is the deep system which is generating as much stain and earthquakes in the appliances, the hours and the depths, there is something clear, there is again a new intrusion of magma at depth as he spent the last June 24... almost nothing... and the worst is that we may have more seismicity on the rise the next days... and deformation of course and we will see the gases that will continue throughout this. In the updated map of today have been 43 localized earthquakes, 12 yesterday and 7 of antesdeayer, although in the spectrogram and seismogram of CHIE are quite a few more, with more than one hundred per hour in the last hours giving a tremor, spasmodic depth where it is difficult to locate them and who have not been located and much microseismicity. In the first part of the day localizán in the area of the swarm more shallow the Gulf but the second part has been in the profound that it has reactivated with trend in the last hours to move the seismicity toward the S - is towards la Restinga.... The magnitude of the earthquakes today reaching 2.8 for the deep system and 2.6 for the surface. Today as when the eruption above plus senses earthquakes, vibrations are continuous in areas such as el Pinar, La Restinga, San Andrés, in various parts of urban Frontera and Tigaday, Los LLanillos, Las Lajas, Las Toscas, Los Mocanes, and more sites such as tip, Sabinosa, La table, El Mocanal, Tamaduste and La Caleta and up to the stand on the beaches. In some places also come accompanied by sounds and shocks and tremors are discernible in the liquid from a bottle almost throughout the island, as a tremor, probably by the continuous train of earthquakes that is suffering the island. As for odors have not reported. None has not been reported on the strange behaviour of animals. As a curious thing this morning until you liara all this I received reports of noise and vibration from other islands, specifically from la Palma and Tenerife, which occurs previously to Reactivations in iron, curious how much less. Today with so many earthquakes, reaffirm a message from Louis of very little from the previous post, inviting all to pass through the animation utility of the web AVCAN (Henry). "There will be able to confirm your intuition: in the right pane click"View last 24 hours"and keep the box marked in the box top left on the map of"Keep points": http://www.avcan.org/?m=Animacion" (Luis) remind all that it is very important if you feel something of all this, it is appropriate to report it to the IGN have documented what was in addition to the importance that has to monitor the possible area of opening of an eruptive mouth... It is very important.

It has picked up the magmatic activity in El Hierro with about 60 earthquakes

VICENTE PÉREZ | Santa Cruz de Tenerife

Seismic activity associated with the volcanic process existing in El Hierro yesterday experienced a significant upturn, with about 60 movements between 1.6 and 2.8 degrees located up after 22.00 hours, according to the data which at that time had disclosed on its website the National Geographic Institute (IGN). However, there were hundreds of other non-localized.

This activity is distributed on two levels, with a series of earthquakes originated under the sea in the Gulf against Sabinosa at depths ranging from 8 y11 kilometers and another swarm, on land, under the area of border and Los Llanillos, between 18 and 21 kilometers deep, with numerous epicentres in the Summit.

The vibrations were felt in different areas of the island, as this newspaper has seen although the IGN has only recorded that one sense, out of 2.6 degrees, to the 10.26 hours and 10 kilometers of depth to Sabinosa...

Note special 100 c, the tracking of earthquake and volcanic activity of El Hierro, still very moved, sismicamente speaking, the system moves, you're pressurizing (3.2 earthquake of a few hours ago so indicates it, may we have today some)not something more strong if you continue to pressurize and clear, this indicates still has not found a way out, so it still down there XD.On the seismicity map, today have been located 108, almost all major 2.0 and the truth is that in are last hours the seismicity is despalaza SSE in direction to la Restinga in an axis NNW - SSE from the Gulf as another eruption, but this time points to pass just below the village of la restinga... and may even El Pinar.
