Next eruption of Bardarbunga volcano could come soon

Massive volcano in Iceland is ready to BLOW - and experts warn it could cause travel chaos
The Bardarbunga volcano has been hit by a series of earthquakes in recent days

One of Iceland's biggest volcanoes is preparing to erupt, and experts warn the ensuing ash cloud could cause travel chaos across Europe.

The 6,590ft Bardarbunga volcano, which is hidden under the ice cap of the Vatnajokull glacier, has been hit by a series of earthquakes in recent days, measuring 3.9, 3.2, 4.7 and 4.7 on the Richter scale.

Now scientists are warning that pressure inside the volcano's magma chamber is increasing, suggesting it could erupt within the next few years.

Volcanology expert Pįll Einarsson told the Daily Star that the latest quakes are part of a series that have been "in progress for two years", claiming that the volcano is "clearly preparing for its next eruption".

Disaster expert Dr Simon Day, of University College London, added that the earthquakes could "precede a large explosive eruption and consequent widespread ash fall".

The Icelandic Met Office has listed activity levels at the volcano as "high", but has not yet issued a warning.

Bardarbunga is one of the most active of Iceland's 130 volcanoes. Its last eruption in 2014 was the strongest in Europe for more than 240 years.

The eruption blew out two cubic kilometers of volcanic material over the course of several months - nearly ten times more than the Eyjafjallajokull eruption in 2010, which grounded 100,000 flights across Europe.

However, Dr Thomas Walter, from the GFZ German Research Centre for Geosciences, said that the 2014 Bardarbunga eruption could have been a lot worse.

"The event was a blessing in disguise as the eruption could have happened directly beneath the ice," said Dr Walter.

"In that case, we'd have had a water vapour explosion with a volcanic ash cloud even bigger and longer lasting than the one that followed the eruption of Eyjafjallajokull in 2010."

Einarsson told the Star it is "impossible" to predict when the Bardarbunga volcano will erupt again, but said Icelandic authorities must take action to prepare for "more disastrous eruptions"

A new caldera, measuring a diameter of one kilometres has been formed in this last week in Öręfajökull glacier, a caldera spotted via satellite images of the glacier.

Iceland's volcanoes may be ready to blow

According to the Iceland Met Office this caldera shows increased activity in Öręfajökull which is located in Vatnajökull, Iceland's largest glacier.

A great sulphuric stench has eminated from the river Kvķį last week.

Increased seismic activity has occured in the area in recent months, activity which has subsided in recent days. The volcano hasn't erupted since 1727. There are still no signs of an imminent eruption states an announcement from the Met Office. However, the safety code has been put up to yellow.

Bįršarbunga trembles: 4.1 magnitude quake on Saturday

Determined not to let Öręfajökull and Skjaldbreišur hog all the attention over the weekend, the monster volcano Bįršarbunga trembled on Saturday morning. A powerful 4.1 magnitude quake was detected at 6:19 AM on Saturday morning, in the southern edge of the volcano's caldera.
Read more: Scientists determine sub-glacial volcano Bįršarbunga is showing increased geothermal activity
Bįršarbunga has been showing high levels of activity for more than a year now, caused by the re-filling of the magma chambers of the volcano following the 2014-15 Holuhraun eruption. The last major quake in Bįršarbunga was on December 3. Seismologists at the Icelandic Meteorological Office say there are no signs of imminent volcanic activity in Bįršarbunga.

Intense earthquake swarm at Tjornes fracture zone
An intense earthquake swarm is taking place at Tjörnes Fracture Zone volcano near Grimsey island, Iceland over the past 7 days. More than 1 100 of earthquakes were detected in this region since Wednesday, February 14, 2018. The last known eruption of this submarine volcano was in 1868.

The largest earthquake so far was M4.1 at 19:37 UTC on February 15, about 10 km (6.2 miles) ENE of Grimsey. "It is the largest earthquake detected in the seismic swarm that began a week ago and is still ongoing," the Icelandic Met Office said late Thursday. EMSC registered this quake as M3.7 at a depth of 14 km (8.7 miles).

A magnitude 3.2 earthquake occurred at 19:28 UTC in the same area, followed by two events above M3, at 19:38 and 19:39 UTC.

There are no signs of volcanic unrest, IMO said. "This area is part of the Tjörnes Fracture Zone and earthquake swarms are common in the area."

More earthquakes, even bigger, cannot be ruled out, the agency added.

A total of 1 165 earthquakes were detected since 08:56 UTC on February 14. 11 of them had magnitudes above 3, 162 between 2 and 3, 951 between 1 and 2 and 41 less than 1.

leuke swarm inderdaad, groter dan normaal, maar de update van 20 februari geeft aan dat er geen harmonic tremor is waargenomen en de conclusie is dan ook dat het tectonic van aard is.
Op zich wel jammer :P

Toch maar weer hopen op de Katla, want die is nog steeds due. Tenzij die kleine eruptie die niet door het ijs kwam is wat we kregen.
Dan toch maar weer blijven hopen op Hekla, want zij is ook al 10 jaar over due :P

M4.1 earthquake hits Bardarbunga volcano, Iceland

Magnitude 4.1 earthquake was registered in the southern part of the Bardarabunga volcano caldera, Iceland on March 21, 2018. The quake hit at 22:56 UTC at a depth of 4.5 km (2.8 miles).

It was followed M2.6 at 23:02 and 2.5 at 00:38 UTC, March 22 and half a dozen of smaller quakes, but there are no signs of volcanic tremors.

These are the first quakes in the volcano since the end of January when Bardarbunga was hit by the largest quake since the end of the 2014/15 eruption.

Bardarbunga earthquakes March 21 and 22, 2018

Bardarbunga, one of the most powerful volcanic systems in Iceland, has been showing a significant level of activity in recent months, Iceland Magazine reports. These quakes are caused by magma being thrust from the Earth's mantle up into the lava chambers of the volcano. The volcano has been re-filling it's lava chambers since the end of the 2014-15 Holuhraun eruption.

Öręfajökull volcano showing clear signs of unrest, Iceland

Öręfajökull volcano in southeastern Iceland, the largest active volcano and the highest peak in Iceland, is showing clear signs of unrest with an inflation phase for at least a year and a half. The last eruptive episode of this volcano started in August 1727 and ended in May 1728.

The inflation is ongoing and is reflected by increased seismicity and characteristic deformation pattern, Icelandic Department of Civil Protection said July 13, after a series of meeting with scientists from The Icelandic Meteorological Office, The University of Iceland and Iceland Geosurvey.

There are no signs of a decrease in the inflation rate or the seismicity and the state of unrest persists despite a decrease in geothermal activity since last December.

The source causing the inflation is most likely injection of new magma, scientists said. The volume change since the start of the unrest is of the order of magnitude of 10 million m3 (about 0.2 m3/sec) comparable to the intrusion activity in Eyjafjallajökull some years before the eruption in 2010.

New resistivity measurements indicate the presence of geothermally altered rocks at shallow levels inside the caldera consistent with intermittent high-temperature geothermal activity as seen in many other volcanoes.

Referring to possible scenarios and hazards, scientists said that Öręfajökull is in a typical preparation stage before an eruption but the temporal evolution and the outcome is unknown. Increase in the geothermal activity with associated floods and gas release is a possible scenario.

Considerable earthquake swarm in Katla volcano

Since early this morning (2-August-2018) there has been considerable earthquake swarm activity in Katla volcano. This earthquake swarm started yesterday (1-August-2018) at low rate but during the night and after a minor stop the earthquake rate increased and at the moment this earthquake swarm can be considered ongoing.

Green star is the magnitude 3,6 earthquake in Katla volcano. Copyright of this image belongs to Icelandic Met Office.

Largest earthquake so far had a magnitude of 3,7 and the second largest magnitude has been 2,2. Other earthquakes are smaller in magnitude at the moment. No change in harmonic tremor has been observed at the moment. There is a lot suggesting that glacier water from hydrothermal areas under Mżrdalsjökull glacier are now flooding into Mślakvķsl glacier river. I got a report of that over facebook yesterday, but nothing has been confirmed officially at the moment.

Sleeping giant volcano Katla trembles: Sharp earthquake swarm in caldera

Katla, a giant volcano hidden beneath the ice cap of Mżrdalsjökull glacier in South Iceland, which towers over the town of Vķk, has been relatively calm and quiet for several months, following growing signs of activity in the past couple of years. Seismic activity in Katla is taken very seriously, as the volcano is under close supervision, as the volcano has erupted very regularly every 60-80 years. The last eruption took place in 1918, making Katla long overdue for an eruption.

The National Seismic Monitoring System of the Icelandic Meteorological Office recorded the earthquake swarm yesterday evening. The largest of the nearly two dozen quakes was a relatively powerful 3.1 magnitude quake at 21:39 (9:39 pm). This quake had an epicenter 6.5 km (4 mi) east-northeast of Gošabunga peak (29 km/18 miles, north-northwest of Vķk) at a depth of 100 meters (330 ft). The initial tremor was followed by close to a dozen smaller tremors.

Van Katla denk ik al jaren dat hij gaat uitbarsten, maar ze blijft stil... Ik heb eens gekeken naar de geschiedenis van de vulkaan, en ik denk dat ze in de laatste 1000 / 2000 jaar nooit zo lang zich koest heeft gehouden. De vele earthquake swarms die er nu al jaren zijn, tonen toch wel aan dat ze zeker actief blijft, en er mogelijk iets geblokkeerd is van lavatoevoer.

Dan is het wachten tot die blokkade van toevoer... het plots begeeft, en dat kan dan uitmunten tot een zeer geweldadige eruptie, of tot dat de toevoer van lava een andere weg onder het gesteente vindt, en de lava migreert tot een andere locatie relatief dichtbij de vulkaan en dan zich opstapelt tot een dyke, en zo tot een spleeteruptie uitmondt. Dat tweede is echter nog niet het geval, omdat de swarms zich nog steeds in de vulkaan zelf plaatsvinden. Maar het kan wel, zoals in de 10e eeuw bij de Eldgja eruptie.
