Volcanos in Iceland, possible alarm?

I have just added a new page with research links for Iceland

qvsdata.wordpress.com...

There is not much on it yet but I am building it up. It takes a long time as I have to look at my collection and then go and find the articles again on the net and make sure they are downloadable.

Well, seems my prediction came true.

At the moment everything seems a bit quiet there is no talk in the media that there is going to be a eruption right away, but the news here say it should have started some time around last night, but there was no indication that it was allready starting when that was said in the news.

Grímsfjall

If this eruption is anything like the 2004 eruption then people have nothing to worry about.
But im guessing that is just the start of it, im thinking there will be more activity then just this.

I´ll post when something happens, seemd to be pretty mutch coverd in the other thread.

This just in from John Search

Grimsvotn Volcano, Iceland
Melt water continue to flow from Grimsvotn volcano, Iceland. The rate has slowed compared to previous days. An increased in electrical conductivity in the Súla river indicates that geothermal water is draining from the western side of the Skeiðarárjökull glacier. Earthquakes continue to occur under Grimsvötn volcano indicating that floodwaters flow under the glacier. There is no indication the volcano is currently erupting.

Posted this on the Volcano watch thread, though I should include it here too.

Status report - 3 November 2010 - Seismic tremor at Grímsvötn

Indeed yes. The tremor here is being caused by the water - just wanted to point that out if you were not clear.

Presently, there are no detectable signs of the beginning of a volcanic eruption at Grímsvötn.

This release of water is a regular thing. Grimsvotn needs to go wee wee every 5 years or so

All looking relatively quiet today. At GRF the tremors are falling off and GOD et al including HAU are steady.

Links to them all here

Check out this nifty Link - Volcanoes of Indonsia

Sorry - posted this in the wrong thread - still a nift link though

Everything is still quite quiet here, nothing new being reported on Grímsvötn, bit worrying seing the larger quakes near Katla and Torfajökull. It´s just a matter of time now untill something happens, but untill then chao.

Well it´s been pretty eventful lately, but there are no news to report nothing seems to be stirring about.
This is the last 48 hours , but this time it´s not the X that marks the spot, it´s the Star.

There seems to be alot of theory´s about that these events are linked together. I myself had wonderd about the quake that hit a few months back in Indonesia that showd up on a few reports around the world, we reported a 6,5 i think it was.

Well,, otherwise,, loads of activity here in Iceland, nothing more to report on Grímsvötn then has allready been reported, it seems to be taking a piss. Otherwise there seems to be alot of activity in all the volcano´s that are overdue and also Esjufjöll seems to be waking up. (scary thought)

Enjoy this google translate of a report this morning from Visir.is

The decline in hydrological in rivers, streams and water resources in the vicinity of the volcano Hekla is greater than that explained solely by the drought and lack of snow in the mountains.This is the estimate of Hjartardóttur Driva , former senator, who lives in the Springs Rangárvellir. "This is unusually high considering that it is due to precipitation solvent *," says Drífa and says that the decrease was about thirty centimeters in the Springs Physicians at her home. "And this has happened to an eruption, some weeks and months earlier, the water has hripað like down. " This development follows a hurry to have taken place in all fall and has increasingly narrowed the doctors. "I have lived long in the Springs and never seen such a small brook before." Sverrir Haraldsson, farmer in Under Rangárvellir, in the vicinity of Hekla, believes, however, profit on them due to less flow in the Hekla volcanic activity. "You feel time nothing mysterious in a few snow-free winters and little rainfall at all," he says and says water does not have gone very quickly. "But it has increased when a lot this year." As soon Sverrir said it right check that there are signs leading up to the eruption of Hekla to reduce the amount of water in the vicinity of the mountain. "But it just has not been normal in frequent craft," he added. In the area of people wonder, however, admitted that whether the changed water status may be an indication that an eruption is coming. Hjörleifur Sveinbjörnsson, a geologist at the Icelandic Meteorological Office, said no seismicity has been recently in the vicinity of the mountain. "There are no earthquakes and no see the expansion suggest," he says, but thinks can not be excluded that the low water position in the vicinity of the mountain is available for a longer run-up than are earthquakes. „Hekla er náttúrlega löngu komin í stöðu og þannig séð tilbúin. "She 's a natural long been ready for a eruption . " But indicators have never shown any particular lot sooner than this to two hours before an eruption, "he says, and recalls that this was it just be the last Hekla eruption." Then came the first smáskjálftar about two hours earlier and could not see a change in expansion meters At the same time emphasizes Hjörleifur to unusually low precipitation has been widely and has fallen in rivers and lakes. Fast drying may be an indication of imminent eruption, but the trend in recent weeks and months is rather due to lack of rainfall.

I can´t quite take this report that seriusly as there has been a record drought here in Iceland this summer, but you never know.

Mm. I take it seriously. As you know I have been saying for some time that Hekla is more likely to blow than Katla. It is just a feeling I have had for some time.

We have had a few quakes in the Vatnafjoll / Torfajokull area which make me nervous.

By the way the GPS data is back. Maybe my scathing email did the trick?

reply to post by PuterMan


Yeah thought that post would interest you, it´s strange that the geoligist in that story doesn´t even mention activity in torfajökull, are you speaking the sudden revival of Esjufjöll, i gotta say i can´t begin to understand what is going on right now, the whole country seems to be active yet nothing is happening

reply to post by Spacedman13


Had to think about that for a minute. Not Vatnajokull, Vatnafjoll which if I am not mistaken is under or somewhere by Tindfjallajokull.

Still popping the off small one off in that area. Definitely one to keep any eye on.

Esjufjoll seems to be quiet as is the Vatnajokull area at present.

A few excercises going on?

Neat. Well spotted.

Let's hope they remain as exercises and nothing more!

Well we got some new activity here in the Reykjarnesskaga area , the area seems to be rising and this apparently has happent before, here´s the reports (google translate i tried to fix it up)

Scientists now closely monitor seismic episodes and land uplift with Krýsuvík and civil informed of developments. pressure increase in Earth's crust which is considered below can be caused either by the dynamic influx or changes in geothermal systems. Earthquake tremors with 40 quakes became Krýsuvík tonight but seismic wave was resumed in the area this fall after a quiet period earlier this year. Earth civil informed last year of unusually high landrise in a small area southwest of the lake broke, but then rose to a country where about three centimeters. Land rise was attributable to increased pressure in the Earth's crust in three to four kilometers, according to Freysteinn Sigmundsson geophysicist tion. This increased pressure was ascribed either of magma influx or variations in geothermal systems. Land rose went back last winter and the first half of this year and then began again in spring. Sigrid Hreinsdóttir geophysicist says that it has been decided to patrol the area better and to this end has two new GPS-meters have been set up earlier this year. Seismic wave quests autumn scientists were not surprised and had some time before they let civil knowing the expected shifts in the region. Scientists are not sure what's going on there, but most lean to the land rise can be explained by changes in the geothermal system, possibly associated with magma movement. Is not expected to eruption is coming, but the reason is believed to patrol the area well.

This is the country at the moment, we got some quakes in areas there usually aren´t any quakes in.

As you can see there´s loads of activity at the moment and with this new activity of this area, there are 3 volcanic area´s in that area here are small descriptions off google translate

"Reykja­ne­s­kerfið"
Westernmost volcanic system on the Reykjanes peninsula system. It reaches roughly from Reykjanes to departments from the northeast of the peninsula. It also includes some miles southwest of the seabed. The area belongs to the high temperature Svartsengi region. There is also bigger and "fun old" dyngja, Sandfellshæð than lava from her has reached 100 square kilometers. Other large and similarly old dyngja the system is in spite of Shield.

There were eruption in the 10th and 12 century, but then goes over great several eruptions the years 1211-1240. This cycle began with the eruption of view far from the country but then urðu several eruptions in the coming years in similar areas, ie near the sea offshore. One has been the most prominent, in 1226 and leaves a ash lair who has used well in ash legal studies in the Southwest. Sources for this eruption of Oddi protected log and there is talk of "Sand Fall Winter in Iceland." Eruptions happent then up in the country in the coming years and generate two (meg-in-lava-fillets), another near the South-Western Reykjanes and the other, much larger, covering almost the peninsula from south to north. the lava are prominent in the vicinity of Svartsengi and the Blue


"Trölla­dyngju­kerfi"
The system is named after a novel dyngju in the system. It is probably not wrong told to say that Trölladyngja system is among the most dangerous volcanic system of the country because of its proximity to the capital. Northernmost fissure is just southwest of Hafnarfjordur and lava has at least. in two places happened nearby west of town after the settlement.

About the year 1150 - 1151 were significant eruption in the system and opened some fissures in that cycle. Have these been mentioned Krísuvík volcanic fires. Then there was also an eruption of the 1180th Structural Neck However, it does not appear to have erupted in the system in Reykjanes Fire on 13th century

"Brenni­steins­fjalla­kerf­inu"
Southernmost part of the system is Krísuvík Bjarg it stretches so in the northeast and into the White Mosfellsheiði. As in the two volcanic systems on the peninsula were considerable metabolism of the system shortly after the settlement and in fact all earlier Sulphur Mountain system. Some soda were probably in two volcanic cycle the area from the Blue Mountains to the cold. This eruption were just before and just after the millennium. Sources say eruptions in the system several centuries later, until 1389, but it has not been confirmed

These area´s are suposed to erupt around every 800-1000 years and on this website they say the eruptions might last for a couple of hundred years. It´s been 770 years since the last eruption. This is something worth watchin

Yes I see we have had a couple of good bumps further down the ridge in the last two days.

About 950 Km off the Icelandic coast however so not a biggie.



A bit off topic folks but you might enjoy this. (I was researching the area spacedman was referring to when I came across this site)

World Of Waterfalls (Dynjandi, Iceland)

Haven´t been posting lately been quite busy in rl, also the activity would seem below average compared to the last year. So i haven´t had the need to post the status. But what i have noticed is that the activity seems to be at, Ridge, Katla,Grímsvötn,Askja, and the north area. The activity at the ridge seems really steady but there have been no reports of more landrise or draining of the lake there.


In the last 8 Hours we have had 3 quakes next to Hekla.

Linky to the area (purple lines in the map are cracks in the ground)

As you can see the quakes are originating at the end of the Hengill region wich ends right next to Hekla, and from what i have learned and posted previusly in this post, is that Hekla and the Hengill region are directly linked as the last eruption in Hekla coused a Swarm in the Hengill region.

But when i was trying to find out what coused Hekla to erupt the last time, i failed in doing so and only discoverd the above statement. But after looking a bit clooser at the quakes that were happening at that time, i noticed that the last time Hekla erupted. The reykjarnes ridge area had been pretty active(wich is quite normal) except for the fact that upto the eruption there had been a increse over the erlier few month at Kleifarvatn, wich is peaking in activity right now, other area´s of the country back then seem to be the same as now, except there was no activy in Askja as there is now , and there was much less activiy in vatnajökull.

So basicly people what im saying is, (hope im wrong) but like last time all the data seems to be pointing towards this. 2 things are possible to be about to happen, Hekla will erupt and compared to last time it will happen within 2-4 weeks , or The reykjarnes ridge area is about to erupt after being dormant for 800 years, (suposed to erupt in 100 more years). Either way should be quite interesting seing how this develops. Becouse if im right again then im pretty sure this can be used as a way to predict possible eruptions.

Either way, happy new year every1 and thx for the one gone past.

Hi Spacedman, and a Happy New Year to you as well.

These two links may shed a bit more light on that for you.

This earthquake is part of the the SISZ. Not Hekla volcano

Fake Hekla eruption, earthquake swarm in Krísuvík volcano

reply to post by PuterMan


Hey hey thanks for the link to to the wave form, quite informing it´s strange that they don´t mention how hekla affected that region after the 2000 eruption as it clearly had a huge effect back then, i actually went on facebook the day after i wrote that and saw "Hekla started to erupt" had a mild shock then i saw the story, it was from 2000. Pretty funny coincidence.

This is the story they were linking to facebook hoax


Im still going to predict what i said becouse the activity back then has real similarities to what is happening now, i would even say that there is more activity now then back then. Only real difference is that there is more activity in vatnajökull and back then there was a steady swarm in the hengill region before and after ,, now what we have seen is that swarm that went north a couple of months ago, upto Langjökull and Hofsjökull.

Also while going through the last years and such there was a quake east of the country a single m5.2 quake east of the country Image from what i can see is that there has never been a quake there before or after that. I was wondering what you´d think of it, any chance that the plume might be moving a different direction instead of going southeast like it has , it maybe has shifted and started going north east? (pretty sure im wrong about the plume though didn´t do any research on the location and how long it takes move, from what i recall it was in 10.000 thousend of years) Pretty wierd getting a isolated quake where there aren´t any foult lines near?
