הר געש באיסלנד התפרץ בפעם השנייה ב-900 שנה


התפרצות נוספת בהר פגרדלשפאל, ליד ריקיאוויק ונמל התעופה.
אחרי 10,000 רעידות אדמה נפלטה לבה מסדק געשי, במרחק של ק"מ ממוקד ההתפרצות הנדירה אשתקד - שנמשכה חצי שנה.
איסלנד פרסמה "קוד אדום" למטוסים.
הר געש התפרץ אתמול (רביעי 3/8/22) באיסלנד, בקרבת עיר הבירה ריקיאוויק ונמל התעופה הבינלאומי של המדינה.
ההתפרצות הייתה אחרי כמה ימים של פעילות געשית מוגברת באזור: מיום שבת דווח על כ-10,000 רעידות אדמה - שתיים מהן בעוצמה של 5 דרגות לפחות.
בתמונות מאיסלנד נראית לבה נפלטת מסדק געשי הסמוך להר פגרדלשפאל שבחצי האי רייקאנס. ההתפרצות הייתה במרחק קילומטר מהסדק שהתפרץ בקרבת ההר במרץ 2021.
אלפי תיירים נהרו אז לאזור כדי לצפות בהתפרצות, שהסתיימה כעבור שישה חודשים. זו הייתה הפעם הראשונה שהר הגעש פגרדלשפאל מתפרץ מזה כ-900 שנה. 
כולל כותב ומנהל אתר זה וזהו הלינק לביקור שלי בהר הגעש:-


פוסט של חסקין על ההתפרצות הנוכחי.

כעת התפרץ זו השנה השנייה ברציפות.
ההתפרצות הייתה במרחק 25 ק"מ מהבירה ריקיאוויק, ו-15 ק"מ בלבד מנמל התעופה הבינלאומי של איסלנד. "כרגע אין שיבושים בטיסות לאיסלנד וממנה", מסר אמש משרד החוץ האיסלנדי.


הרשויות קראו לתיירים ולתושבים להתרחק מהאזור בעקבות גזים רעילים. לפי שעה לא נשקפת סכנה מיידית לתשתיות חיוניות. השירות המטאורולוגי של איסלנד פרסם "קוד אדום" כדי למנוע ממטוסים לטוס מעל הר הגעש. כשהיקף ההתפרצות יתברר ההתראות למטוסים יעודכנו.

Earthquakes Hit Katla Volcano in South Iceland
An earthquake of the magnitude 2.7 hit just north of Goðabunga in Mýrdalsjökull glacier, which covers the volcano Katla in South Iceland, around 8:30 am yesterday morning. It was part of a swarm of minor earthquakes. The second-largest had a magnitude of 1.8.

The Katla area has been rather quiet in the past weeks. There was more activity in the area in the spring when two small glacier outbursts flooded the river Leirá in Kötlukriki and Emstrur, to the west of Mýrdalsjökull, ruv.is reports.

The seismic activity then subsided and GPS monitors showed decreasing tension in the lithosphere.
Yesterday’s quakes were not connected with any volcanic activity and there has not been any increased flow in glacial rivers originating in Mýrdalsjökull.
However, glacial water in the vicinity has smelled of sulfur, according to geophysicist Benedikt Ófeigsson at the Icelandic Meteorological Office, such as in the river Jökulsá at Sólheimasandur and Leirá in Kötlukriki.
Katla has been monitored closely by scientists since a major glacial outburst, possibly caused by a minor volcanic eruption underneath Mýrdalsjökull, tore a hole in the Ring Road in South Iceland in July 2011.

Earthquake Swarm in Northeast Iceland

A series of minor earthquakes, the largest with a magnitude of 3.7, hit 27-33 kilometers east-southeast of Grímsey, Iceland’s northernmost inhabited island, shortly after 7:45 pm yesterday. Most of the other quakes were around a magnitude of two.

Einar Kjartansson, geophysicist at the Icelandic Meteorological Office, told Morgunblaðið that earthquakes of this magnitude hit the region around Grímsey at one to two month intervals.
The earthquake swarm was not out of the ordinary and even though islanders may have felt the strongest earthquake, they were hardly alarmed, Einar said—people are used to the ground trembling in Grímsey.

Katla Volcano Shaking

18.07.2012 | 00:00

Katla Volcano Shaking, Geologist Says

During the volcanic eruption in Eyjafjallajökull in 2010, an eruption that closed the airspace of Europe, many talked about the bigger and more active volcano, Katla, which is thought to be due to erupt at any moment. However, it has been due to erupt for almost fifty years. The latest Katla eruption in 1918 caused considerable damage and the volcano is feared wide and far.

The famous Icelandic volcanologist Haraldur Sigurdsson notes in his blog on July 17 that small earthquakes in Katla volcano have been frequent in both 2012 and 2011. In the accompanying graph you can see the number of earthquakes each year from 1991 to 2012. The situation is clearly not normal since the peak is in 2012.

Haraldur asks whether these are ice-quakes formed by movement and melting of the glacier, or quakes in the crust of the earth, connected to the volcano itself. He draws the conclusion from observing quakes in Godabunga, west of Katla, that it is unlikely that the quakes are related to melting of ice due to the glacier. Hence, he says that possibly the quakes are related to geothermal heat under the ice. Haraldur Sigurdsson concludes by saying that Katla continues to cause nervousness among all.

Foreign Reporters Enter Icelandic Volcano

Up to 40 foreign journalists and five foreign television channels have entered the volcanic crater Þríhnúkagígur in southwest Iceland in recent weeks. Managing director of Inside the Volcano Björn Ólafsson calls the crater a “diamond in the rough”.

Björn believes Þríhnúkagígur has the potential to become as big an attraction as the Blue Lagoon. His company started lowering travelers into the crater two weeks ago and Björn said foreign journalists have taken a keen interest in it, ruv.is reports.
Currently, only a limited number of people can enter the crater at the same time. However, there are ideas of drilling a tunnel into the crater for tourism purposes.

According to the Icelandic Metrological Office, some aftershocks followed, but they were all significantly smaller, Morgunblaðið reports.
Seismic activity is very common in this area as it lies on the borders of the Eurasian and North American continental plates north of Tjörnes peninsula. No one reported to have noticed the earthquake on the Icelandic mainland.

Seismic Activity in Katla

21.06.2012 | 11:00

Increased Seismic Activity in Iceland’s Katla Volcano

Increased seismic activity was detected in Mýrdalsjökull glacier in south Iceland, under which the volcano Katla lies, last night. Twenty-six minor earthquakes were picked up by sensors, all of which had their epicenter within the Katla crater.

A seismic activity expert on watch at the Icelandic Meteorological Office informed ruv.is that the earthquake swarm had started at 1 am and continued through 5 am.
However, there is no reason to be concerned about an imminent volcanic eruption or glacial outburst in Katla. The earthquakes were all shallow and originated in seismic activity in the geothermal system.

Grímsvötn Volcanic Eruption Causes Glacial Melt

12.06.2012 | 06:00

Grímsvötn Volcanic Eruption Causes Glacial Melt

Geophysics professor Magnús Tumi Guðmundsson said there are still consequences from the May 2011 eruption in Grímsvötn, a sub-glacial volcano in Vatnajökull in southeast Iceland, including more rapid melting of the icecap.

grimsvotn_ps

There is a 45°C (113°F) hot lagoon on the glacier’s surface, an uplifting by three centimeters has occurred as the icecap decreases and the water surface of glacial rivers continues to rise, Morgunblaðið reports.
“We assume that significant melt will occur in the western Vatnajökull this summer,” predicted Magnús Tumi, who recently returned from a research expedition to Grímsvötn on behalf of the Glacial Research Association.
During the expedition, researchers sailed on the lagoon in Grímsvötn. “It is remarkable because it’s very hot. In the crater there was a little stream with 45°C warm water. A few hundred meters wide part of the lagoon was at bathing temperature, 25-40°C.”
“The eastern part of the lagoon is considerably colder, yet lukewarm, which is noteworthy given that it is surrounded by a wall of ice,” Magnús Tumi continued. The high temperature is a leftover from the eruption last year.
And the ash fall continues. During dry and windy conditions, ash will blow across south Iceland this summer and even longer.
Large drifts of ash have accumulated by the Ring Road in south Iceland. Drivers are asked to be careful because the ash might blows across the road and block visibility, Fréttablaðið reports.

Quakes Hit Katla Volcano in South Iceland

11.06.2012 | 11:57

Series of Quakes Hit Katla Volcano in South Iceland

A series of earthquakes began in the sub-glacial volcano Katla in Mýrdalsjökull, south Iceland, shortly before 5 am this morning. Between 5 and 6 am 14 minor quakes were registered there, the strongest of which had the magnitude 1.6 points.

Between 6 and 8 am, six other minor quakes were picked up by the Icelandic Meteorological Office’s sensors, but after that the series subsided, visir.is reports.
Geographer Sigþrúður Ármannsdóttir at the Icelandic Meteorological Office, said the epicenter of the quakes were in the ice cauldrons that opened up during what probably was a minor eruption in Katla last summer, when the river Múlakvísl flooded, tearing a hole in the Ring Road.
Sigþrúður believes they were caused by geothermal activity. She added that increased conductivity that has been measured in Múlakvísl lately might indicate that geothermal water is leaking into it.
Approximately one month ago a small glacier outburst occurred in Katla which lasted a few days. Seismic activity in the volcano was picked up by sensors, as well as increased conductivity in Múlakvísl.
The reason was also believed to be increased geothermal activity in one of Katla’s craters.

More Grímsvötn Eruptions Expected in Near Future

More Grímsvötn Eruptions Expected in Near Future

Eruptions in the sub-glacial volcano Grímsvötn in Vatnajökull, which last burst in 2011, can be expected every five to ten years in the coming decades, according to geophysicist Magnús Tumi Guðmundsson. A group of scientists is currently studying the volcano.

The geothermal area in Grímsvötn is clearly visible to the group, which comprises representatives of the University of Iceland Science Institute, Landsvirkjun – the National Power Company and the Glacial Research Association.
They traveled to Vatnajökull a few days ago to put up GPS monitors, take samples from the glacier and read meters, ruv.is reports.
The crater that formed at Grímsvötn during the eruption last year measures 1.5 kilometers in diameter. It used to be covered in water but most of it has now evaporated. The water is hot and steam emanates from it.
Grímsvötn eruptions come in series, each of which lasts 60 to 80 years, Magnús Tumi explained. The last series began in 1996 with eruptions following in 1998, 2004 and 2011, which was the largest by far, causing extensive ash fall.
“One can expect the development to continue in the next few decades that regular eruptions will occur in Grímsvötn with approximately five to ten year intervals,” he said.
“However, Grímsvötn lie far away from human settlements and if they are on a small scale they don’t have much of an impact,” Magnús Tumi concluded.

Lava Caves in Iceland

30.05.2012 | 06:00

Damaged Lava Caves in Iceland to Be Closed

The Icelandic Speleological Society would like 15-20 caves in Iceland to be fenced off in the next few years to prevent them from being damaged any further. At the same time, access to the caves should be improved so that they can be observed safely.

Guðni Gunnarsson, chair of the Icelandic Speleological Society, told Morgunblaðið that he can name many examples of damaged caves, including Víðgelmir in west Iceland, which has practically been stripped of its stalagmites and lava straws.
Similarly, the appearance of Leiðarendi in south Iceland has undergone drastic changes since its discovery 20 years ago.
“It is very sad what happened with Leiðarendi. It was very beautiful when it was found but in the past 15 years everything has been removed from inside it. One of its most magnificent lava formations, a large stalagmite, was taken in 2007, even though it was clearly fenced off,” Guðni said.
Some caves have been closed already, both to cave expeditioners and others, such as Jörundur in south Iceland.

Volcanic Activity near Reykjavík?

28.05.2012 | 12:33

http://www.whatson.is/icelandreview/search/news/Default.asp?ew_0_a_id=390364

Volcanic Activity near Reykjavík?

Volcanologist Haraldur Sigurdsson, one of the world’s most respected scientist in his field, said that land rise in Krýsuvík, about 20 kilometers from Reykjavík, Iceland’s capital, could mean that volcanic magma is streaming into the earth’s crust.
Land in the Krýsuvík area has risen about eight centimeters in two years and the area is watched closely because it could be an active volcano. The last eruption in the area was about 800 years ago and the lave in Hafnarfjördur, a town south of Reykjavík, came from that area.




Sigurdsson says that even though there may be magma movement it is by no means certain that it will come to the surface as it did in 1151, forming the laves Ögmundarhraun, north of Grindavík on the south coast and Kapelluhraun by Hafnarfjördur. Alcan’s aluminum smelter is situated in Kapellluhraun.

The volcanic area goes from Grindavík in the south to Heidmörk on the outskirts of Reykjavík in the north.
Sigurdsson told RÚV that a possible eruption would be along that rift and lava would flow from it. “But nothing indicates that an eruption is imminent. But geological history and the information that we have on that area indicate that this is possible and therefore both Iceland Met and the University of Iceland follow this area closely.”

Minor Glacial Burst in South Iceland Volcano Katla

Minor Glacial Burst in South Iceland Volcano Katla

A small glacial burst occurred in the volcano Katla, which lies underneath the Mýrdalsjökull icecap in south Iceland, on April 28 and lasted a few days. The activity was registered by seismic monitors and increased conductivity was measured in the river Múlakvísl until May 7.

Last summer a large glacial burst, probably caused by a minor eruption in Katla, caused the river to swell and tear a hole in the Ring Road, right at the height of the tourism season in early July.

Oddur Sigurðsson, a geologist at the Icelandic Meteorological Office, told visir.is that the glacial burst in late April was so insignificant that it couldn’t be detected by the naked eye.
Oddur explained that it was caused by geothermal activity in one of Katla’s craters.
Volcano enthusiast and blogger Jón Frímann Jónsson reported on two events in Katla, on April 28 and May 6 or 7, and considers them to be warning signals: something is happening in the volcano, he predicts.
He also commented on the recent series of earthquakes which hit Herðubreið in the northeastern highlands early this week.

Series of Earthquakes Hit Northeast Iceland

A series of earthquakes began near Mt. Herðubreið in the northeastern highlands at noon yesterday and was still ongoing this morning. The largest quake measured 3.2 points on the Richter scale but most aftershocks, approximately 100, were below two points.

The most seismic activity was noted between 8 and 11 pm last night. A few quakes hit this morning but now the series seems to be subsiding, ruv.is reports.
It is common for series of minor earthquakes to hit the region near Herðubreið and there are no indications of upcoming volcanic eruptions or other activity in the area.
There were some concerns of volcanic activity by the nearby volcano Askja earlier this winter but scientific research concluded that there were no indications of an imminent eruption.

Icelandic Volcanoes Said to Be Growing Restless

Icelandic Volcanoes Said to Be Growing Restless

Two years ago, the eruption of the volcano Eyjafjallajökull caused havoc across Europe, with airborne ash grounding flights for six days. 

Eyjafjallajökull may be quiet now, but, according to The Telegraph, activity has been increasing in the volcano belt that stretches diagonally across the middle of Iceland from the Westman Islands in the south to the Lake Mývatn area in the north, along the line of the American and Eurasian geological tectonic plates.
This region includes the volcano Katla, which has erupted about every 60 years (the last time in 1918), the volcano Hekla, which has erupted approximately once every ten years in the past decade (the last time in 2000), and Grímsvötn, which had a short eruption last year. 
In the 17th and 19th centuries, eruptions of Eyjafjallajökull were followed within months by eruptions of Katla, and now too, Katla has been increasingly restless. 
Increased activity has also been detected in the volcanoes under the largest ice cap, Vatnajökull, which is where Grímsvötn lies. 
In July 2011, geothermal heat caused melting in Mýrdalsjökull, the ice cap covering Katla, producing a flood that destroyed an important bridge on the south coast of Iceland at the height of the tourist travel season. 
According to precise GPS measurements, there has been movement of the surface of the volcano, as well as bursts of high earthquake activity beneath Katla’s caldera, indicating that magma has risen closer to the surface. 
Scientists have been monitoring the volcano closely ever since the glacial burst last July and every now and then earthquakes have caused concern that an eruption might be coming up. Yet while repeatedly making headlines last autumn, Katla has been rather quiet in recent months.
The scale of the damage from an eruption in Katla would depend on the direction of the wind, as well as on the style, size and duration of the eruption.
A major eruption of Katla could cause flooding, poisoning of agricultural land, destruction of property, interference with air traffic across Europe, and even global cooling for several years. 
This is because Katla is likely to produce very fine ash, as did Eyjafjallajökull, which would remain airborne for days.
However, scientists stated in January that due to increased knowledge, better surveillance and more accurate forecast models—and the experience drawn from the eruptions in Eyjafjallajökull and Grímsvötn—future eruptions will cause fewer disturbances to air traffic than in 2010.
The University of Iceland is working with Delft University of Technology and other institutions to develop more accurate systems to track and predict volcanic activity, in order to deal with the threat and damage of eruption.
Last week the story broke that Askja volcano in the northeastern highland might be preparing to erupt as its crater lake, Öskjuvatn, was iceless despite frosty temperatures.
Travelers have been warned about visiting the area and scientists have launched a research expedition to determine the likelihood of an eruption.

רעידה קלה בהר הגעש Slight earthquake in KATLA

בתאריך 8/11/2011 הוגשה רעידה קלה בהר הגעש ולהלן הדיווח מה- ICELAND REVIEW

November 09 | New Quake in Iceland’s Katla Volcano Was Felt in Vík

An earthquake of the magnitude 3.2 on the Richter scale hit yesterday morning in the southernmost part of the Katla caldera in Mýrdalsjökull glacier. Tremors of this size are rather common but because of its epicenter it could clearly be felt in Vík and the vicinity.
Several local residents reported the quake to visir.is. It was followed by another one measuring 2.5 points on the Richter scale.
According to a statement from the Civil Defense Department, no further quakes were picked up by sensors in the area after 10:20 am yesterday.
The Icelandic Meteorological Office reported yesterday that there is no visible volcanic activity in the southernmost part of the Katla caldera but earth scientists continue to monitor the developments there closely.

Minor Series of Earthquakes by Katla Volcano



Six earthquakes measuring between two and three on the Richter scale—the strongest of which was close to three—were picked up by sensors on Mýrdalsjökull glacier in south Iceland, close to the volcano Katla which lies underneath the icecap, yesterday. 

Another tremor, measuring 2.1 on the Richter scale, followed in the night along with some smaller quakes. Earth scientists are monitoring the area due to increased seismic activity in the past months, visir.is reports. 

This latest series of earthquakes is considered to be similar in character as those preceding it and not an indication of any other activity in the volcano, as stated in another article on visir.is

Last week sensors picked up 535 earthquakes in the entire country, including two series which hit north of Siglunes by Siglufjördur in north Iceland and off Reykjanes peninsula in the southwest. The largest quakes measured 3.4 points on the Richter scale. 

In past weeks manmade earthquakes have been reported as a result of Reykjavík Energy pumping water into the ground on Hellisheidi, upsetting the inhabitants of Hveragerdi. Last week much fewer tremors caused by this activity were reported than the week before.

Three Sharp Earthquakes Hit North Iceland

Three earthquakes measuring well over three points on the Richter scale, the strongest of which was 3.6 points, hit 34 kilometers north of Siglufjördur, north Iceland, yesterday morning. 

The staff of the Icelandic Meteorological Office informed visir.is that earthquakes are common in this area and there were no reports of people having felt the tremors. 

What meteorologists thought would evolve into a series of earthquakes later subsided and the area was quiet last night, visir.is reports. 

Instead sensors picked up a series of minor earthquakes in another area well-known for seismic activity; seven to nine kilometers northwest of Reykjanestá in the southwestern part of the country. 

According to mbl.is, all the earthquakes were rather small although about ten in the series measured above two points on the Richter scale.

Sharp Earthquake by Askja in Northeast Highlands

An earthquake measuring 3.4 on the Richter scale was picked up by sensors to the north of the outer Dyngjufjöll mountain range by the volcano Askja in the northeastern highlands at 4:15 am. It was the largest in a series of minor earthquakes last night.

There has been some seismic activity in the area lately with the ground trembling this week and last, according to the Icelandic Meteorological Office, mbl.is reports.
It was pointed out that the earthquakes didn’t originate inside the Askja crater itself, but rather to the northwest of it.
The strongest earthquake last night appeared to be relatively shallow, yet neither the quake nor the recent seismic activity is necessarily an indication of any other activity brewing in the area.
It is rather common for earthquakes to hit the region; a few years ago some series of earthquakes were picked up there.
