Either waking up a bit, or rolling over. 3.6 today with a good amount of smaller quakes.

Nothing special from the news media , they are reporting the 2,9. But no statement from any geoligist, so im guessing they are still just on standby to see what develops out of this, as we all are

reply to post by Spacedman13


Yeah, I think it is quieting down for now. It snored a couple of times today with 26 very small eq's. I don't think all of them have been looked at yet, so that number will probably go down. They even have one of those negative mag eq's listed.

Seismic activity increases again at Iceland’s Krýsuvík volcano

March 6, 2011 - ICELAND – It appears that Krýsuvík volcano earthquake activity is increasing again. This time around it appears that the earthquake activity in Krýsuvík volcano has moved more to the west then last weeks earthquake activity. The biggest earthquake so far is a ML2.1 earthquake with the depth of 6.9 according to automatic data on Icelandic Met Office web page. The new earthquake area in Krýsuvík volcano. It is more to the west then the earthquake area that was making earthquakes last week. -Jonfr

Good catch! There was quite a bit of shaking yesterday with over 100 eq's. I wonder if it is going to keep it up this time, or go back to sleep.

en.vedur.is...=table

Looks like activity is back to normal for Iceland after a recent quiet spell.





I thought it may have been more affected by the recent world quake activity we've been having lately, seems like i was wrong.

Where are you spacedman?

What is happening with your volcano?

i tried starting up a new clean thread, was shut down. I honestly don´t know if i want to belong to community that has moderators that don´t listen to reason. I was told that they do pick the most informative thread when they select, but apperently "Breaking news" is more important then "Fragile Earth" so i was shut down.

But i guess i should have just posted my stuff here like always. Here´s the thread i started up www.abovetopsecret.com... .

It refers you to a another thread that has some new updates but it´s mostly the same you have seen on the news, and here´s the other thread i was originally refered to, www.abovetopsecret.com...

Some cattle has died and there´s a huge ashcloud there reached Hveragerði and was suposed to reach reykjarvík yeasterday but it didn´t. Hveragerði is over the main Hengill region to give you a refrence to location. Our airspace is opening up today at 17:00. Bit premature if you ask me , but it´s clear the goverment is not going to let this affect our tourist season at all. And the volcano seems to be quiet, which is really odd as this is the big one, im guessing that was just the warm up and there´s going to be a real fireworks show in less then a few days.

I hope it's not a warm up but just a little hug or hello from that one.

It seems it took everyone by surprise as I can't recall anyone or any "news" mentionning a possible eruption at Grimsvotn past week. At the moment it's just sit and wait.

reply to post by Spacedman13

.....But all fooling aside my friend, there is no way any man can predict when a volcano erupts. Best information i can give u is info that has allready been posted here on ats....

Star and Flag for the thread.


There have been attempts to predict the likelihood of earthquakes. The facts are also related to volcanoes.

There is this informal research M.A. Vukcevic: Earthquakes and Geomagnetic Storms

And there is also this peer reviewed research:

Relationship between global seismicity and solar activities

Abstract
The relations between sunspot numbers and earthquakes (M≧6), solar 10.7 cm radio flux and earthquakes, solar proton events and earthquakes have been analyzed in this paper. It has been found that: (1) Earthquakes occur frequently around the minimum years of solar activity. Generally, the earthquake activities are relatively less during the peak value years of solar activity, some say, around the period when magnetic polarity in the solar polar regions is reversed. (2) the earthquake frequency in the minimum period of solar activity is closely related to the maximum annual means of sunspot numbers, the maximum annual means of solar 10.7 cm radio flux and solar proton events of a whole solar cycle, and the relation between earthquake and solar proton events is closer than others. (3) As judged by above interrelationship, the period from 1995 to 1997 will be the years while earthquake activities are frequent. In the paper, the simple physical discussion has been carried out....

Planetary Configuration:

Implications for Earthquake Prediction and Occurrence in Southern Peninsular India

www.scribd.com...

ABSTRACT

Though there have been several attempts at earthquake prediction from different perspectives, this attempt aims at establishing planetary configurations as a definitive means of earthquake prediction. When two or more planets, Sun and M oon are aligned more or less in line (0o or 180o) with the Earth, then the Earth would be caught in the middle of a huge gravity struggle between the Sun and the planets. T he gravitational stresses would change the speed of the Earth in its orbit and when the speed of rotation of the earth changes the tectonic plate motion also gets affected. T he total angular momentum of planets involved in earthquake triggering mechanism can be calculated and the total force acting at the epicenter in a direction opposite to that of the earth’s rotation can also be determined. At the epicenter, the speed of rotation of the earth can be calculated with the help of available software. So the planetary forces in the opposite direction to the rotation of earth act as a triggering mechanism for the accumulated stress at faults and plate boundaries to be released abruptly. T his does not, however, mean that earthquakes will occur at all edges of the plate boundaries. Two of the parameters contributing to the triggering of an earthquake at a place are a) distance of epicenter from the planet position and b) direction of force acting at the possible epicenter. From the analysis of “ significant earthquakes” over the past 100 years from all over the world and from Southern Peninsular India, the relationship between (i) latitude, longitude, and magnitude of the tremor and (ii) distance from the planet and direction of forces acting at any point can be inferred. Such inferences already made for different localities in other parts of world have unfolded an accuracy of more than 75% with regard to earthquake prediction.

eruption Grímsvötn
Monitor the situation

23. May 2011 - kl.18: 45

Common base and service IES report was released at. 17:00.

The height of the smoke has been around for 5 to 9 miles past times than it should be remembered that the very sharp winds on site which may affect the hill. Side Mocha Circle is to the south. At 8 km and higher east winds and then goes that part of smoke in the west.

Much volcanic ash was from Vik in Myrdal and east Öræfajökull. Most volcanic ash has been in the vicinity of Kirkjubaejarklaustur. Ash dust has been observed in many students from the country's northwest side. Has declined since the volcano yesterday. No lava was a crater in the morning.

IMO, recently received a loan from lidar National Centre for atmospherics Science (NCAS) in the UK. Lidar instrument is based on a laser beam shooting into the air and measure its reflectance. The device had been installed under Eyjafjoll to measure fokösku but was transferred yesterday to the Department to monitor the ashes over the pitch. On at. 20 last night took the device to show an increasing amount of ash in the air and remained there through the night.

IMO located on Miðnesheiði, near airport. Starring veðursjá variant is to monitor rainfall, which measures the reflection from water droplets in the atmosphere. It has been shown that veðursjáin can also be used well to monitor eruption smoke but she sees her reflection in the various arguments eruption partical smoke.

The glacier eruption revealed that Veðursjáin was useful tools, but the distance to eruption center (which was 160 km) reduced somewhat from the quality of the data. Because of this it was decided to purchase a transportable X-band tic veðursjá and get another loan from italian civil protection during the purchase. Mobile veðursjáin is now located near Kirkjubæjarklaustur or in the 80km distance from the eruption site Grímsvötn. Employees We monitor the development of the volcanic eruption with two veðursjám.

23. May 2011 - 14:45

The eruption tension was rumbling s.l. night and still is. Longest tension have remained roughly 40 minutes. earthquake activity has been low. The smoke has been in the 8-10 km altitude so far this day. GPS devices that show the movement suggests that active magma in the magma chamber under Grímsfjall.

East and northeast directions states across the country today and ash has been to the southwest and south in the lower layers. Widely expected to ash fall, although perhaps most notably the northwest corner of the country. Wind will go north later, first in the lower laws, but in the upper layers in the evening and night. Map showing the distribution of ash is under construction and will be published later today.

22. May 2011

The eruption is much stronger than it was in 2004 Grímsvötn and somewhat more powerful than the eruption of the eruption. Today the smoke has been for about 10 km and again at 11 km. Veðursjá new mobile service that was performed in the vicinity of Vatnajökull shows this trend. Confirming that erupted in Grímsvötn is in their box near the place which erupted in 2004. Last ran from 31st Grímsvötn October 2010, a little water has gathered together and thin ice on the carton. When Grímsvötn erupted in 1998 and 2004 there was a Glacier Burst shortly after the eruption began. Is not expected to corresponding conditions are down now and do not expect the ice circuit.

Meteorological Station joint report and IES was released at 22.05.2011. 17. Overall, has declined slightly since the eruption was at its peak last night when the magma flow may have reached over 10 thousand tons per second. Fluid flow afternoon is considered in the order of 2-5 tonnes per second. No lava was a crater in the morning.

21. May 2011

At about 17:30 today, began to measure increased restlessness with sources in or near Grímsvötn and eruption is now started. From the plane was on route from Akureyri to Reykjavik and from 18 to 20,000 feet saw mocha than it does now from Egilsstadir to Selfoss.rticle

There´s a feature now on www.vedur.is... that shows you the predicted flow for the ashfall.

"Hádegi" means noon
"miðnætti" means midnight

And the gray dot means area´s there have been reported ashfall on areas

Never mind, these things happen but I have to say that I cannot understand the logic of shutting down a site by an Icelander in favour of one by a Brit. Not logical Mr Spock.

Seems to me that the tremors are declining slowly looking at the GRF tremor plots. I note that the report you posted said that the eruption was stronger than the 2004 eruption. I am assuming that because we did not hear anything about that one in Europe that it passed quietly by and caused no problems.

Do you have any idea how much stronger this one is supposed to be? (I am just being lazy!)

reply to post by PuterMan


Well they are mostly basing that on how much smoke and ash fall came out this time around, as for quakes there was much more activity back in 2004, but less larger quakes. In 2004 there were 160 quakes reported in the base eruption site, compared to only about 50-60 this time around in the first 3 hours. And about 15-20 in other area´s reaching all the way down to Katla as seen HERE from this picture posted by berkleleygal. And from the tremorplot it seems to have spiked upto about 7500 hz but then right away balanced down to around 4000 hz , but i cannot confirm this as the picture im looking at is miniture at this PAGE that page shows all the data for the 2004 eruption, google translate should come in handy there. But this time around it looked like this [atsimg]http://files.abovetopsecret.com/images/member/7455d694d774.gif[/atsimg] so it looks like there was more tension in this eruption then the 2004 one.

Here´s a picture of the location and depth of the quakes of the site back in 2004

Compared to the one of this eruption.

They also go on to say on the page i linked you to on the 2004 eruption that the tension was mesured on the tremor plots reached all the way to (Hekla)Haukadal og Grímsstöðum(Near krafla) But this time around it was far more powerful as it reached all the way to grindavik which is one of the furthest stations in the west of the country
[atsimg]http://files.abovetopsecret.com/images/member/4371df4d849b.gif[/atsimg]

And Leirhöfn one of the furthest to the north as you can see on the overview Link [atsimg]http://files.abovetopsecret.com/images/member/4c5d055a26d7.gif[/atsimg]

Latest update on www.vedur.is...

25. May 2011 - 10:15

On at. 21 last night the smoke went as high as 7 km and at. 2 of the night went his height of 12 km and then fell down. Lightning was detected at either time. On at. Saw 4 to 5 km high vapor streaks the eruption, after which steam have been 100-300 m height. London VAAC (Volcanic Ash Advisory Centre) has been reported to smoke not detected and is not expected. Tension fell down at. 9 last night and at large. 2 tonight, but still shows a degree of unease Grímsfjall and near volcanoes. No earthquakes in the eruption.

I am not liking what Jon Frimann is saying.

That could go off suddenly with a mega explosion if pressure is building - tremors going on and no visible signs.
