Buildings Collapse As Quake Hits Eastern Turkey
0 Comments
8:32pm UK, Wednesday November 09, 2011

A 5.7 magnitude earthquake has hit Turkey, causing some buildings to collapse in the east of the country, according to a news agency in the country.
The tremor comes just weeks after a 7.2 magnitude quake hit the eastern province of Van, killing more than 400 people.

According to Dogan news agency, the quake brought down buildings that were damaged in last months' incident, including a hotel and an office building.

The earthquake struck at around 21.23 local time (19.23 GMT) at a depth of 4.8km.

Panicked people could be seen running through the streets, as rescue workers searched through the rubble.

The Cabildo of iron will be put in operation a webcam service that will make it possible to follow the evolution of the volcanic phenomenon that since a month ago in real time, 24 hours a day, takes place in La Restinga. The Cabildo has been working for weeks on this project, that it will happen in the next few days thanks to the collaboration of Telefónica, reported sources of the island Corporation.
At this time, Telefónica is doing necessary tests to guarantee the bandwidth required to bring stability to the signal, due to the great interest which has aroused the eruptive phenomenon of the calm sea around the world. In the coming days will be to know the IP address that internet users can see in real-time what is happening in the southernmost point of the island of El Hierro.
The implementation of this project responds to requests made to the island by private individuals and companies institution, and the stimulus which aims to give the Cabildo of iron to the spread of this phenomenon, by its scientific and tourist interest.

It's a shame Telefónica doesn't put as much effort into sorting out all the problems we paying customers have with their service. (Bitch over)

PS That's the Cabildo of El Hierro they're talking about as the literal translation of hierro is iron.

This is a giggle translation from the AVCAN facebook page.

https://www.facebook.com/pages/Actualidad-Volc%C3%A1nica-de-Canarias-AVCAN/163883668446

Now listening on the radio news, have commented as new demand that the population of El Hierro is starting to do so have teams of psychologists dealing with people that what is going wrong, something required from the outset in this emergency situation.. .by risk sísmico-volcánico on the island of the Meridian, but the truth is that he listened while I was flabbergasted to such demand, because the reality is that displaced there teams of first aid psychological / psychological intervention in situations of Crisis more than one month. A shame that little culture of emergency existing in the Islands, the involved administrations and the population itself barely has made use of this important service since they began to feel the first symptoms.

As many of you will recall, on 8 October two days before the start of the eruption!, AVCAN published an article in which indicated some of the measures of collective protection they had moved to the iron, with the intention of promoting among the population a feeling of being protected against what could happen by emergency systems. This is the link to that article:

http://www.avcan.org/?m=Noticias & a = news & N = 903

Which includes this paragraph:

"In the context of the current time of this seismic crisis, it should be mentioned that Red Cross has shifted to the island of El Hierro personnel qualified for first aid psychological care, a very useful tool for those people who feel that the current situation they can exceed or collapse." Their assistance may be helpful. If you think that you or any person in his environment may need this service, do not hesitate to get in touch with the Red Cross to volunteers carefully they channelled them to appropriate resources. "

We reiterate in mentioned in the preceding paragraph. When it was published and linked it to this forum, there were some comments stating that it was an exaggeration, that there was no need psychologists or tilas, or anything that (until then used to finish my messages with "calm and tilas"...)

It is normal that at first there is the feeling of rejection, but over time the need for REAL somehow channel the feelings of impotence, rabies, fatigue, loneliness, fear, etc. that an emergency as this generates, especially if it is so bulky in the time just assimilating...

Since AVCAN was detected from the outset that this aspect could be a problem for some sectors of the population herreña, because he had symptoms become serious by the volume that could cover (economic, social and labor crisis together around the volcano and its movements), and have been needed almost four months of earthquakes and eruption so that socially and POLÍTICAMENTE begins to demand something of this. But is that the aid has already been there since before the eruption! Think that in fact, are the unique "tirita" that until the moment SE HAN post in EL HIERRO (as far as first aid is concerned).

From AVCAN want to publicly acknowledge the work that so far have made security and emergency services displaced and/or located in El Hierro, and in particular to those people or organizations that altruistic mode have been collaborating as volunteers, as it is the case of the Red Cross who have been there all these weeks doing just... what to do

Posted on Avcan this morning from a Spanish person

Translated .

Araceli Santana, sorry for not having replied earlier, more than anything so don't think that you do not do case...I don't mind that you say that I am the most suspicious so nothing to forgive. can you tell me any reason to trust the Canarian tv or ign? Truths are not half truths. The Canarian tv is the TV of the Government and the "script" this preset. Ign likewise (recalls that Nemesio also are "agreed" in the dome of the ign). Haran scientists what they can but with the media that stop them...Ign changes graphics and "loses" earthquakes. The Canarian tv is a disc grated apart from giving the minimum information and say that all we are already seeing. I trust more than others such as Nemesio, Ortiz or Carracedo.(it is rare that all of them in some way disagree among if or IGN or CSIC; and the combinations arising). I am concerned, now returning to the present time, the reduction of earthquakes almost as much as mutism information because "gallo who does not sing, something has the throat", I'd rather feel the volcano "heartbeat" or listen to the "Bell" of the cat. Greetings, Araceli and can tell me what you want...

Do tides affect Volcanos ? (This subject is being discussed in relation to El Hierro on the internet at the moment)



Do tides affect volcanoes?
Tidal Lunacy

Everybody is familiar with ocean tides that cause the ocean level to go up and down, usually twice a day. We can go down to the beach and watch this tidal action along any coast in the world. On a global level, the ocean tides are actually waves whose crests are half a world apart and traveling from east to west. At most points on the globe, the tidal crest comes by about every 12.5 hours.

The engine driving this phenomenon is the gravitational attraction of, primarily, the moon, but also the sun. The earth completes one rotation every 24 hours, and the ocean tides can be imagined as a watery bulge that remains relatively stationary while the planet rotates inside. The biggest tides occur about every two weeks when the sun and moon are aligned (either full or new moon). Hence they are called the "fortnightly" tides.

Few realize that the solid earth also exhibits tidal behavior with bulges on opposite sides of the globe, also driven by the moon. At HVO, we can actually measure these tides with our tiltmeters and strainmeters. The earth's surface tilts up to 0.03 microradians in response to the apparent passage of the moon overhead. A tilt of one microradian is the tilt of a solid bar one kilometer (0.6 miles) long with one end raised by the thickness of a dime. To emphasize how small the tidal tilts are, our tiltmeters automatically alert us to the possibility of volcanic activity when tilts change more than 0.5 microradians in 5 minutes.

Who would have thought that the moon had that kind of power, not only to be able to cause the world's oceans to bulge, but also to squeeze terra firma twice a day? But it does, so it should not come as a complete shock that reputable scientists have suggested that these squeezings might influence whether a volcano will erupt or not.

The idea is that if a volcano is full of magma, the squeezing at the fortnightly tidal maximum might be just enough to overcome the resistance of the crust, push magma out, and get an eruption going. Once started, the eruption would continue on its own.

More than 25 years ago, a pair of earth scientists compared the records for 680 eruptions that occurred since 1900 and found that "the probability of an eruption is greatest at times of maximum tidal amplitude." In plainer language, volcanoes are more likely to erupt at the fortnightly (or 14-day) "high" tide.

A specific look at 52 Hawaiian eruptions since January 1832 shows the same sort of pattern. "Nearly twice as many eruptions have occurred nearer fortnightly tidal maximum than tidal minimum." HVO scientists have noted that the Pu'u 'O'o fountaining episodes each occurred remarkably close to fortnightly tidal maximums and that the first set of eruption pauses in 1990 (periods where the eruption turned off for up to a few days) occurred remarkably close to fortnightly tidal minimums.

Great! Now let's start predicting eruptions based only on this information. The fortnightly tidal maximum occurs at full and new moons, every 14 or so days. The next tidal maximum will be the new moon on November 15 - will Mauna Loa erupt then? Almost certainly not.

Although this is a fascinating correlation, there are just too many tidal maximums and too many volcanoes to base predictions on tidal cycle alone. In the Hawai'i example of 52 eruptions since January 1832, there have been nearly 3,900 tidal maximums, of which roughly 3,850 of them went by without causing an eruption. Statistically, this is about a one percent chance that any tidal maximum will affect the start of an eruption.

The correlation is more important as a clue to how volcanoes work. The effect of the tides suggests that a volcano can remain in a state of near eruption for a period of time before some threshold is exceeded and an eruption starts. There are probably many possible mechanisms for exceeding that threshold - the lunar tides are but one.

Earth Tides and Volcano Monitoring

The gravitational attraction of the Sun and the Moon produce the familiar ocean tides and the less familiar earth tides. Why are volcanologists interested in earth tides? Earth tides are cyclical, small, and slow ground movements that we use to calibrate and test sensitive volcano deformation- monitoring instruments. They might also trigger volcanic events.

The tides are slight bulges of the ocean's or Earth's surface that face the Moon and the Sun as the Earth rotates on its axis. There are actually two lunar and two solar tidal bulges, one on the closest and the other on the farthest side of the Earth. The lunar bulges are a little more than twice the height of the solar bulges. At new and full moon, the Sun and the Moon are aligned, and the lunar and the solar bulges add together for the greatest tidal range. At first- and third-quarter phases of the moon, lunar and solar tides are in opposition, and the tidal range is at a minimum. The tides go through one full cycle (a high and low tide) about once every 12 hours and one full cycle of maximum height (a spring and neap tide) about once every 14 days.

When there is a large earthquake or when you are near a source of volcanic tremor, you can feel the ground move. At other times volcanic ground movements are so small or slow that they can only be measured by seismometers, tiltmeters, strainmeters, or other sensitive geophysical sensors. Movements of magma occur over periods from minutes to days, outside the detection range of most seismometers.

The slow ground movements associated with magma moving underground can be detected with tiltmeters and strainmeters. We install these instruments deep in the ground to isolate them from the daily and yearly heating and cooling of the ground. How do we test whether they are working?

The periods of the earth tides are in the same range as those associated with magma movements, and they provide a critical test for the response of the deformation instruments. The earth tides are quite small and can only be measured with the most sensitive instruments, such as those deployed by HVO.

The forces that produce the tides are a tiny fraction of the forces that cause earthquakes and eruptions. Even though the forces are small, they can trigger an event. Scientists have found no correlation between the tides and earthquakes. Correlations between the tides and eruptions, however, have been identified.

Most people are not even aware that there are earth tides. These slow and rhythmic undulations of the Earth's surface are used by volcanologists to calibrate and test sensitive deformation- monitoring instruments. They can also trigger volcanic eruptions.

Im following Raymond Matabosch on Twitter because he has over 40 years experience of following volcanos all around the world and is in El Hierro watching what is going on. Raymond seems to think that there is another eruption due based on the C02 levels.

Update 10/22 – 13:08 UTC:
 - The French press starts to arrive at El Hierro ... but the activity has gone ...
 - Joke reports that there is ZERO to see at the moment
 - The Guardia Civil – Involcan helicopter has just made his daily overflight (Involcan is taking gas samples above the vents – see graph below) and came to greet the journalists at the viewing point
 - At 11:30 the La Restinga city council met in El Pinar to discuss solutions how to survive this crisis
 - Only 6 people are currently in La Restinga
 - and the webcam ... he is till showing the image from yesterday. We hope that the La Restinga councel will do something about it – this is truly bad publicity for El Hierro

Data Update 10/22 – 11:13 UTC:
 - Harmonic tremor and frequency are showing still activity but with a limited number of bursts.
 - Since midnight UTC the earthquake activity can be called "weak" compared to prior days. Only 8 quakes with magnitudes 1.5 or higher.
 - Max. magnitude since midnight : 2.7.
 - Shallowest earthquake being at a depth of 18 km.

Update 10/22 – 10:55 UTC:
 Joke just arrived at Montaña Naos (Naos mountain) a viewpoint area 150 meter above sea level.  She reports that a faint eruption zone is forming again, but without bubbles in the middle like we have seen the prior days

Could this be the calm before the storm?

[fifi]

Could be Surfjames, tremor has started to increase again and an increase in gasses has been mentioned several times as an indication of an eruption on the way. http://www.ign.es/ign/head/volcaSenalesAnterioresDia.do?nombreFichero=CHIE_2011-11-10&ver=s&estacion=CHIE&Anio=2011&Mes=11&Dia=10&tipo=1

Soar CO2 levels in El Hierro
 Canary Institute Volcano Island detected in 1,400 tons of carbon dioxide

PEDRO WAR – SPECIAL ENVOY THE IRON CO2 levels have skyrocketed in El Hierro in the last hours. If last week's rate of emission of carbon dioxide and was 3.5 times higher than normal, with more than 1,200 tons per day around the island building, yesterday the figures identified by scientists at the Institute of the Canary Islands Volcano (non-tip) already exceeded the 1,400 tons per day in a place where the emission is normal average of 340 tonnes. Over 900 tonnes of CO2 per day and is considered an abnormal emission of carbon dioxide. CO2 is the first gas that emerges from the depths in a volcanic eruption and could mean that the magma moves with intensity for a out. Normally, the release of CO2 is a warning of a possible eruption. http://www.laprovincia.es/especiales/2011/11/10/disparan-niveles-co2-hierro/414654.html

[jand]

Yes Fifi you can see the harmonic tremors increasing on this graph and there look like burst of explosions again  (I think that is shown by the gaps in the green).

They are definitely much bigger than they were anyway jand.

Thats interesting....have a look at the same graph for some of the other Islands....the gap is even larger?

[fifi]

I think its the one mouth just scanned at different times jand.


The team of the Spanish Institute of Oceanography (IEO), aboard the
Ramon Margalef ship has been able to observe the rapid growth of undersea volcano
El Hierro by maps made on different days.
The first image shows the morphology of the area on October 24, 14 days
after the eruption began and the second represents the same area four
days later and it can be seen considerable growth in both the cone
as volcanic casting
             ............................
I was reading somewhere this morning that they need the base to widen a bit more before it gets really explosive...will try and see where I read it and post it here.

Above post translated.

Report of Canarian renowned geologist Juan j. Coello Bravo on the material referred to informally as "restingolita", the most characteristic of the products emitted to date by the underwater eruption that is currently recorded in the South Ridge of the island of El Hierro.




ON THE ORIGIN OF THE "RESTINGOLITA"


Bravo Juan j. Coello
Geologist


Santa Cruz de Tenerife, to November 9, 2011



I. introduction


This brief report is drawn up following consideration of visu of several samples of the material referred to informally as "restingolita". Its production only responds to own needs of the author of register, order and interpret the observations and the data available to date. This necessity arises from scarcity and dispersion of the information on this subject, of undoubted interest for the geology of the Canary Islands and the future of the ongoing volcanic crisis, have provided the scientific community and the public in general the members of the Advisory Committee of the volcanic emergency and plan some research centres involved in the study of the eruption in progress. Its development does not therefore meet the formal request of any agency or individual.


The author is grateful to the director of the Museum of nature and the man of Tenerife, D. Lazarus Sánchez-Pinto, provide for personally, these samples.



II. structure and composition of the restingolitas


The restingolitas, informal name applied to the most characteristic of the products emitted to date by the underwater eruption that is currently recorded in the South Ridge of the island of El Hierro, are floating fragments of size decimétrico - perhaps until metric - and forms with globular trend of glass volcanic vaculares and light. Some of which have been able to be observed by the author seem to present an outgoing or bump elongated as a keel. Its presence in surface was detected for the first time 10/15/2011, 5 days after the start of recording volcanic tremor in the area of the eruption by seismographs of the National Geographic Institute (IGN) (Figure 1).
