There are changes taking place in harmonic tremor on the SIL stations closest to the eruption in Holuhraun. I don’t know what this means exactly, the best idea at the moment is that the eruption is either ending or getting less in power. It is hard to know for sure at this moment due to the bad weather in Iceland. This might also just be part of normal fluctuation of the eruption.

Holuhraun’s magnificent new crater could be on the brink of bursting
BY STAFF |JAN 20 2015



The beautiful new crater in Holuhraun could be on the brink of bursting. According to Gro Birkefeldt Møller Pedersen, geologist and Institute of Earth Sciences' mission leader at the eruption site, air surveillance has shown that fractures have begun to form in the north side of the crater.
Now lava overflows the crater's lower northeast ledge but if the north wall crumbles the main lava flow could find a new outlet, running to the northwest and expanding the ever-growing lava field in a new direction.
The crater has built up close to 100 meters (328 ft.) since the eruption began August 31st (for scale imagine a 20 story high building) and is at least 400 meters (1,312 ft.) long and 100 meters (328 ft.) wide.

Scientists from the Institute of Earth Sciences have just started a new mission to the eruption site. The main objective is to study more closely the composition of volcanic gas emissions from the eruption, Gro Birkefeldt told RÚV. High values of sulphuric dioxide are still being recorded.
According to a status report from the Scientific Advisory Board of the Icelandic Civil Protection, published today, sulfur dioxide was recorded at 1,800 micrograms per cubic meter (µg/m3) last Friday in the town of Höfn in Hornafjörður and around 1,750 µg/m3 in Reykjahlíd village last Sunday. Sulfur dioxide is considered to have reached unhealthy levels when it exceeds 600 micrograms per cubic meter.

Er wordt op dit moment veel water door de Jokulsa afgevoerd, zo'n 2200 m3/sec. Dit is extreem veel. Er is ook veel (drijf)ijs in de rivier bij de brug, die zorgt voor stuwing van het water.
Er stroomt al water over de weg bij de brug. Als de komende tijd regen of verdere dooi wordt verwacht, zal er meer water over de weg gaan stromen.

Een aantal op en langs de Vatnajokull opgestelde apparaten weigert op dit moment dienst. Zodra de weersomstandigheden het toelaten, wordt een herstelmissie uitgevoerd, maar op dit moment zijn de omstandigheden zwaar.

Er komt nog steeds 200-250 Kg SO2 vrij per seconde, zo'n 20.000 ton per dag.
Verder zijn er weinig tot geen ontwikkelingen.

Een aantal electriciteitsmasten wordt op dit moment verplaatst, om voorbereid te zijn op een eventuele gletsjervloed bij een uitbarsting onder de gletsjer.
Ook rondom diverse stuwdammen bij electriciteitscentrales worden extra maatregelen genomen, om de schade in zo'n geval te beperken.

Factsheet
quote:
• Insubstantial changes have been in the volcanic eruption in Holuhraun over the last few weeks. The lava field has thickened substantially but activity on the surface has decreased.
• The subsidence in Bardarbunga caldera was measured from air on Wednesday. The volume of the subsidence is now 1.7-1.8 km3. The change in volume from the last measurement corresponds to a flow of magma from underneath Bardarbunga of about 60 m3 per second. The greatest subsidence is now about 61 meters. Over the last few weeks the geothermal cauldrons in Bardarbunga have enlarged.
• Seismic activity in Bardarbunga continues to be strong. Over the last few weeks it has though been quite weaker than in the first months of the event. No earthquake over M5,0 has been detected in Bardarbunga for 15 days, which is the longest period between M5,0 earthquakes since the seismic activity started in August. The strongest earthquake since the last meeting of the Advisory Board on Tuesday was measured M4,7 yesterday at 03:07. Eight other earthquakes between magnitude M4,0-4,7 were detected over the period and about 37 earthquakes between M3,0-4,0. In total around 150 earthquakes have been detected around the caldera since last Tuesday.
• Around 65 earthquakes were detected in the dyke during the same period, the strongest one was measured M1,5.
• Insubstantial earthquake activity was detected in Tungnafellsjokull, Askja and Herdubreid.
• GPS measurements near northern Vatnajokull glacier show continuing slow deflation towards Bardarbunga.
• Around 2200 µg/m3 SO2 were recorded on Thursday in Reykjahlid and at lake Myvatn. Very high values of SO2, about 84000 µg/m3, were recorded at the eruption site in Holuhraun on Wednesday, being the highest values recorded at ground level since the eruption started.

• The volcanic eruption in Holuhraun continues. Visible intensity of the eruption was low on last Wednesday while various observations were done at the eruption site. Comprehensive cross-section measurements from air (on 30. December and 21. January) show however that the lava field has thickened substantially during these three weeks and that the volume of the lava field is now little less than 1.4 km3. The flow of magma, during this period, was just under 100 m3 per second. The intensity of the eruption is there for slowly decreasing but hopefully it will be possible to measure the volume of the lava field again later this week, which will give new numbers on the flow of magma.
• Seismic activity in Bardarbunga continues to be strong. Eight earthquakes between M4.0-4.9 have been detected since the last meeting of the Advisory Board on Friday. The strongest one was measured M4.9 on Saturday, 24. January at 07:25. About 40 earthquakes between magnitudes M3.0-3.9 were detected over the period. In total around 150 earthquakes have been detected around the caldera since last Friday. No earthquake over M5,0 has been detected in Bardarbunga since 8. January.
• Around 50 earthquakes were detected in the dyke during the same period. Most of them were under M1.0 but the strongest one was M1.6 on 24. January.
• GPS measurements near northern Vatnajokull glacier show continuing slow deflation towards Bardarbunga.

Since last update nothing major has changed in Holuhraun. There have been some changes in Bárðarbunga volcano it self and I am going to cover that later in this article. The magma flow from the craters in Holuhraun remains high at the moment, with latest flow measurements saying that flow of lava is now 100m³/sec. There seems to be uncertain or maybe changes in the flow of lava out of the crater. The volume is now ~1,4 km³. The lava-field has been getting thicker over the past weeks and closest to the craters it is now around 40 meters thick. New estimate of when the eruption might end are now 4 to 15 months.

Earthquake activity remains high, but it continues to drop at steady rate between weeks. Earthquake activity now also drops between peaks in activity. I still don’t know if a small eruption took place in Bárðarbunga volcano. Nothing has yet been confirmed and it might remain unconfirmed for a long time. I am also seeing small spikes in the harmonic tremor data due to hydrothermal activity in Bárðarbunga volcano (far as I can tell).

Notes
• The volcanic eruption in Holuhraun continues, but it has diminished substantially over the last few weeks. Visual activity in the crater has decreased and the lava field is hardly increasing in size.
• Seismic activity in Bárðarbunga continues to diminish although it can still be considered strong. The strongest earthquake since Tuesday was measured M4.3 at 01:26 yesterday. Two other earthquakes stronger then magnitudes M3.0 were detected over the period. In total around 70 earthquakes were detected around the caldera since last Tuesday. No earthquake over M5.0 has been detected in Bárðarbunga since 8. January. A distinct pulse of earthquakes occurred yesterday between 01:25 and 02:10. Time intervals between such pulses have significantly increased from 2-4 hours in the beginning to 12-24 hours or more at the moment.
• Around 65 earthquakes were detected in the dyke during the same period. The strongest one was measured M1.6 today at 08:24 in Dyngjujökull glacier.
• The rate of the subsidence in Bárðarbunga caldera had decreased substantially. But that is not the whole story. Ice is subsiding into the caldera with the effect that the GPS station does not show any changes. The estimated depression of the rock foundation of the caldera, in the light of the ice subsidence, is about 5 cm per day. The flow of magma from under Bárðarbunga is believed to be 25-30 m3 per second, which is about one tenth of the flow in September last year.
• GPS measurements near Vatnajökull glacier show continuing slow deflation towards Bárðarbunga, indicating a flow of magma from under the volcano.
• About 7 earthquakes were detected around Askja and 15 around Herðubreið since last Tuesday. All of them smaller than M1.5.

The activity in the Holuhraun eruption has decreased significantly in February. About two weeks ago, there were two active craters, now lava is being emitted by one crater. The seismic activity around Bárðarbunga volcano under Vatnajökull glacier, which feeds the eruption, has also decreased.

The earthquakes are fewer and smaller than in past months and last week it happened for the first time since increased seismicity was picked up in Bárðarbunga on August 16, that no earthquakes larger than magnitude 3.0 hit in a period of 48 hours. The same thing happened yesterday, as the last earthquake larger than magnitude 3.0 hit on Saturday, ruv.is reports.

No earthquake larger than magnitude 5.0 has hit since January 8. Gunnar Guðmundsson at the Icelandic Met Office’s seismology department said he doesn’t expect an earthquake of that magnitude to hit again and that there are indications that the eruption will come to an end in the coming weeks.

While the eruption’s end seems to be near, volcanologist Ármann Höskuldsson stated a bigger event may be imminent, as reported on Vísir. He spoke at the University of Iceland on February 17. “The mother of it all is Bárðarbunga,” Ármann said, explaining that the magna, which originates from a chamber at a significant depth under the volcano, could start a new eruption.

“It’s a series of divergence … and the alarm starts ringing now that the eruption on the sands [Holuhraun] is subsiding because the event isn’t over. The last divergence series lasted almost ten years with nine eruptions occurring during Kröflueldar,” Ármann pointed out of an eruption similar in nature.

There’s a risk of Bárðarbunga erupting under the glacier, leading to massive flooding. “It’s known that about 1 percent of the magma surfaces. Therefore 100-200 cubic kilometers of magma are still moving around under the volcano. That’s a lot and it’s likely that it will make itself known in the future,” Ármann concluded.

Earthquake activity in Bárðarbunga volcano for the past 48 hours, no earthquake above magnitude 3,0 has been recorded for the past few days. Copyright of this image belongs to Icelandic Met Office.

Earthquake activity continues in Bárðarbunga volcano, but at far lower level than just few weeks ago. Subsidence has slowed down considerably at the moment. It has not stopped. There are earthquakes along the dyke from Bárðarbunga volcano, suggesting that pressure might be increasing in it. That in it self might not lead to a new eruption.

The eruption in Holuhraun continues, but at low level. The only remaining vent that is now open is building a new crater inside the big crater that has now stopped erupting. The eruption might continue at this low level for many more months. Current status of the eruption is not known due to extremely bad weather in Iceland at the moment. The eruption is not over, it is however really small at the moment.

Notes
• For the last few days there has been very poor visibility of the eruption in Holuhraun due to bad weather. Satellite images do confirm that the eruption is still on going.
• Seismic activity in Bárðarbunga continues to diminish. The strongest earthquake since Tuesday was measured M2.5 yesterday, 26th of February, at 01:59. Other earthquakes were all smaller then magnitudes M2.0. In total around 50 earthquakes were detected around the caldera since last Tuesday. No earthquake stronger than magnitude M3.0 has been detected since February 21st and no earthquake over M5.0 since January 8 th.
• Around 60 earthquakes were detected in the dyke during the same period. The strongest ones were measured M1.4 and M1.3. It is worth to mention that bad weather does affect the number of small earthquakes detected.
• The rate of the subsidence in Bárðarbunga caldera last week was about 5 cm per day in light of the ice subsidence into the caldera.
• GPS measurements near Vatnajökull glacier show continuing slow deflation towards Bárðarbunga, indicating a flow of magma from under the volcano.
• Five earthquakes were detected around Tungnafellsjökul glacier, the strongest was magnitude M1.7. About 25 earthquakes were detected around Askja and Herðubreið since last Tuesday. The strongest, magnitude M2.3 was detected in Askja yesterday at 05:42.
• Automatic gas detector measured S02 concentration on 500 µgr/m³ in Blönduós yesterday.

Blij dat ik vorige week geen helicopter vlucht heb geboekt!
Vrijdag was ik aan het paardrijden in de lavavelden en zuidoosten van Reykjavik. Bardarbunga was duidelijk 'ruikbaar' toen in de middag een windje over land opstak.
Ik denk dat zijn gedag zeggen was :-p
Wachten op de volgende uitbarsting zou ik zeggen......elke 2/3 jaar is het prijs ;-)

Had gelezen dat er nu weinig aardebevingen nodig zijn in dat gebied voor een nieuwe uitbarsting. Magma zit namelijk maar 1 km onder het aardoppervlak. Vertelde Jón Frímann op zijn eigen website en die had het weer van het IJslandse vulkanoloog.

Volcanologist: Bárðarbunga Caldera Starts Rising Again

Volcanologist Haraldur Sigurðsson, who predicted the end of the Holuhraun eruption with remarkable accuracy, wrote on his blog yesterday that there are indications that the caldera of Bárðarbunga volcano, which fed the Holuhraun eruption, has begun rising again.

The rising of the caldera could mean that magma is accumulating in the magma chamber, building pressure, which might eventually lead to another eruption.

“When the subsidence [of the caldera] stopped, the curve of the position of the GPS sensor in Bárðarbunga had become horizontal. In the accompanying graph from the Icelandic Met Office’s website a blue curve shows none or insignificant horizontal movement on the surface of Bárðarbunga from February 7 to March 7,” Haraldur writes.

“I added a red line for comparison [see Haraldur’s blog]. It clearly shows that in the past days, the GPS sensor has started rising again. It can be caused by two things: (A) The ice below the sensor is flowing into the depression … (B) The caldera has started rising again because magma from the mantle is flowing into the magma chamber below Bárðarbunga.”

“I’m inclined to believe the latter explanation, but time will tell. If (B) is correct, it is likely that the flow of magma from the depths into the magma chamber will take many years before it reaches the position which Bárðarbunga had before the eruption which began in 2014,” Haraldur concluded.

Other scientists have predicted that Bárðarbunga will erupt again in the near future and that the eruption in Holuhraun was the first in a series.

The eruption carried on while the caldera subsided and magma flowed out of the magma chamber and into the intrusive dike connecting Bárðarbunga, which lies under Vatnajökull glacier, with Holuhraun north of the glacier.

Using data from a GPS sensor in the caldera, Haraldur and his grandson Gabríel Sölvi calculated the rate of the subsidence and when it would stop, which would mean that magma had stopped flowing into the intrusive dike and hence that the eruption had ended.

They had predicted that this would happen on March 4, while the eruption ended on February 27—they were off by five days.

What is going to happen next in Bardarbunga?
It has been few days since the eruption in Holuhraun has ended and everything is quiet for the moment in Bárðarbunga volcano. What is going to happen next is a big question and nobody has the exact answer. Here are few options.

1.Nothing is going to happen. The rift is going to continue without more eruptions.
2.New magma intrusion is going to start soon in Bárðarbunga volcano. New eruption is going to start days to weeks later.

3.There is also high risk in my view of eruptions in Hamarinn volcano (also called Loki-Fögrufjöll). That volcano system is inside Bárðarbunga volcano and dyke intrusion from Bárðarbunga to the south might start a volcano eruption in it. I don’t know how big such eruption would be, it is my estimate. Dyke to Torfajökull volcano is unlikely to happen. I however cannot rule it out at this point.

What is going happen in Bárðarbunga volcano depends on many factors and not all of them are known. What is known is that heat has been increasing in shallower parts of the crust and caldera for the past six months and those signs are not good. What is not known is the time in question. Next eruption could happen tomorrow or nothing can happen for years. There is no way to know when next eruption is going to happen.

Currently I am just monitoring Bárðarbunga volcano and waiting to see what happens next. The text above is just speculation, not fact. It is not clear what is going to happen next. The only way to know that for sure is to wait until next eruption starts and that might be a long wait.

It is my view that Tungnafellsjökull volcano is now preparing for eruption regardless of what Bárðarbunga volcano is going to do (it’s not over there, even if it is on a break at the moment). There is also problem with amount of time when this all started. It is clear that earthquake activity started to increase in Tungnafellsjökull volcano in the year 2012 and it has been increasing since that year. It is clear that with the eruption in Bárðarbunga volcano it seems to have given Tungnafellsjökull volcano more energy and increased it’s activity, why and what the connection between the volcanoes remains unclear at the moment.

A series of tremors hit the Tungnafellsjökull glacier in the Icelandic highlands this morning.

A total of eleven tremors over magnitude 2 were felt in the area this morning, with the strongest – a magnitude 2.9 – coming around 11am.

According to Hildur María Friðriksdóttir from the Icelandic Met Office, tremor waves of this kind are common in the area and are no cause for concern.

Tungnafellsjökull is a relatively small (10 x 5km) glacier to the north-west of the mighty Vatnajökull glacier in South Iceland.

Bárðarbunga Volcano Might Erupt Again

Geologists are now investigating data, indicating that magma might be accumulating again under Bárðarbunga volcano in Vatnajökull glacier. The Holuhraun eruption, which took place between August 31, 2014, and February 27, 2015, was part of a series of events which started in the volcano in 1974 and might provide evidence about the behavior of the volcano in the future.

According to Páll Einarsson, professor of geophysics at the University of Iceland, the next few months will determine whether magma is in fact accumulating. “That’s the big question,” he told RÚV. “There are some indications that this might be the case, but we have to investigate it further.”

The signals, gathered by new equipment on location, are not clear and come from a great depth. Geologists are still learning how to interpret such data.

The Holuhraun eruption is now seen as a chapter in a story that began in 1974. That year, a series of large earthquakes began, which hit at regular intervals in Bárðarbunga. The first chapter ended 22 years later with the eruption and glacial flood in Gjálp in 1996.

After the Gjálp eruption, the volcano was silent for many years, but a few years ago, a new series of earthquakes began, culminating in the Holuhraun eruption in the northeastern highlands in August 2014. The magma came from Bárðarbunga and the caldera sank by 60 meters (197 feet) in the course of the eruption.

Páll believes it’s possible that the next eruption might occur in Bárðarbunga itself. “Bárðarbunga is probably the most powerful volcano in Iceland … Bárðarbunga is the center of a volcanic system which often erupts at the periphery, but still more frequently in the volcano itself.”

It is difficult to predict when the next eruption might start and whether previous eruptions can be used as evidence as to what might happen next. Páll concludes: “We have 30 volcanic systems in Iceland and each one of them has its own personality. To predict what is likely to happen in the near future we have to get to know them a bit personally.”

Katla hit by series of tremors
A 3.3 magnitude tremor hit the south-east of Katla, one of Iceland’s most active volcanoes, in the early hours of this morning.

The main tremor was followed by around ten aftershocks, some of which were shallow and possibly connected to geothermal activity, the Icelandic Met Office reports.

No significant changes to nearby rivers have been reported, but the relevant data will be studied more closely.

“Katla sees this type of seismic cycle from time to time – on average 1-3 times a year,” says the Met Office. “We are monitoring the area closely and will keep everybody informed of any changes. At the moment, things appear to have quietened down.”

Earthquake activity in Bárðarbunga and Grímsfjall volcanoes

Yesterday (17-March-2016) an earthquake swarm took place in Bárðarbunga volcano. This is a weekly cycle at the moment in Bárðarbunga volcano so older readers are used to seeing and read about it already. This started in September 2015 (for the new readers) after the eruption in Holuhraun ended in February 2015. This activity suggest that magma has started to flow into the magma chamber in Bárðarbunga volcano again at faster speeds than before the eruption in Holuhraun. The exact rate is difficult to know, since the magma that started the eruption in Holhraun had been building up in Bárðarbunga volcano since 1970-ish and part of that time earthquake recording was poor or did not exist in Iceland or parts of it until 1995 when the SIL network was created by Veðurstofa Íslands.

The largest earthquake this week had the magnitude of 3,4 while other earthquakes that took place had smaller magnitude. The second largest earthquake had the magnitude of 2,8. Other earthquakes where smaller in magnitude. It is also interesting that part of the earthquake swarm aligned it self along north-south fault in the eastern part of the caldera. That is a new feature, either a weakness is forming at this location or something else is up. This area has around 300 – 500 meter thick glacier on top of it and an eruption at this location would be extremely bad. The glacier flood from eruption at this location would mostly go down Jökulsá á fjöllum glacier river. Other flood locations can’t be ruled out (I’m not an expert on glacier floods and I do have limited knowledge of the landscape under the glacier).

Grímsfjall volcano

It has been five years since Grímsfjall volcano erupted in a largest eruption in 140 years for Grímsfjall volcano. Over the past few weeks there has been a slight increase in earthquake in Grímsfjall volcano. At the moment this doesn’t mean an eruption is imminent, the thing however about eruptions in Grímsfjall volcano is that they happen suddenly and without warning. Normally eruption happens in Grímsfjall volcano every 3 – 5 years on average, sometimes its shorter and sometimes its longer between eruptions.

Notice on Böðvarshólar geophone station

For the longest time now I’ve been having 3G connection issues with Böðvarshólar geophone station. The problems include poor signal, little bandwidth. The poor signal leaks into my recording of earthquakes, making them bad and extremely noisy and that makes them less usable for me. I am going to attempt to improve this situation but if that fails I will have to turn the station down. Since the cost of getting a good antenna for this location is too high and the solution takes too long to implement anyway. I will post a notice if I take down the Böðvarshólar geophone station. If it happens, it is going to happen before I move to Denmark.

Earthquake Hits Major Volcano Site

There was a major earthquake on the northern edge of the Bárðarbunga volcanic craters at around midnight last night.

The quake measured 4.2 on the Richter scale and is therefore the largest quake to have hit the famous volcano since it stopped erupting in February last year.

According to Bjarki Fries, a naural disasters specialist with the Icelandic met office, the earthquake emanated from 3.5 kilometers underground. Around 15 aftershocks have already been measured, the most powerful of which was a 3.5 quake at 01.00 this morning.

Met office earthquakes specialist Martin Hensch told RÚV that there is no evidence of lava movements or of any eruption activity connected to the earthquakes, but that the situation will be monitored carefully. There were two quakes in the same location on April 3, measuring 3.4 and 3 on the Richter scale.

The recent eruption at Bárðarbunga, often known as Holuhraun, lasted from late August 2014 to late February 2015, and despite not affecting aviation or physically threatening any human settlements, it caused dangerous levels of pollution around Iceland and produced more new lava than almost any other eruption in Iceland since the Vikings first arrived.

Is Hekla really going to blow?
The volcanoes of Iceland are some of the most closely watched on the planet. Not only is there an extensive seismic array that records all the earthquakes that occur on the island nation, but many volcanoes have both GPS monitoring of their shape and borehole strain gauges that measure stresses underground caused by these changes in shape. There have been examples in Iceland where sudden and strong changes in strain in these boreholes came right before an eruption, including the 2000 eruption of Hekla. Volcanologists in Iceland are watching for any signs that an eruption might be in the works so that appropriate measures to protect lives and property can be enacted.

That’s why it is a little peculiar that Dr. Páll Einarsson of the University of Iceland warned people and airplanes to “stay away” from Iceland’s Hekla based on his interpretation of accumulated strain at the volcano. According to reports coming out of Iceland, Dr. Einarsson says that strain measured on these strain gauges is higher than it was prior to the 2000 eruption. Also, it has been 16 years since Hekla’s last eruption and, at least for a brief period from 1970-2000 (mind you, this is a very short time for the lifespan of any volcano), it was erupting about every 10 years. Put those together and he thinks that Hekla is ready for its next eruption, and it could happen soon.

However, I am a little perplexed by this statement from Dr. Einarsson and I wish I knew more about the context in which the quotes were given. Without confirmation from the Icelandic Met Office (the volcano monitoring agency), I don’t really know how to assess the validity of what Dr. Einarsson is saying.

Volcanoes care not for your puny human schedules, so you might expect an eruption soon ... or might not.

Does this mean that doom is coming? Not necessarily. As I said, although Hekla did have a pattern of eruptions every ten years after 1970, prior to that the volcano had no eruption from 1947 to 1970, over 22 years. In fact, if you go back to the 1597 AD eruption (again, be wary of any arbitrary starting point for statistics), Hekla has had eight eruptions separated by anywhere from 32 to 79 years (and if I wanted to choose the most common repose interval, it is ~35 years). That being said, volcanoes care not for your puny human schedules, so you might expect an eruption soon … or might not.

Scientists also don’t have strain data going back further than the 2000 eruption of Hekla, so they don’t have a good baseline for understanding exactly how the strain changes before every eruption—just what happened prior to the 2000 event. That’s not to say that they shouldn’t expect something similar, but the data is somewhat scant.

You can actually see the near real-time strain data coming from around Hekla. Now, I am no expert on these readings, but if you compare them to the readings before the 2000 eruption, there doesn’t seem to be much sign of an eruption coming in the near future (that is, next few hours to days). The five gauges are all roughly the same and prior to the 2000 eruption, they all diverged as the new magma intruded the volcano. You can also check out the earthquakes recorded near Hekla and nothing suspicious appears to be happening either.

For an Icelandic volcano, Hekla has a surprisingly explosive history of eruptions. These explosive eruptions have produced ash plumes that reached over 15 kilometers (~50,000 feet). They are also eruptions that tend to be rich in fluorine, which is especially hazardous to grazing animals as they eat fluorine-contaminated ground cover that leads to fluorinosis (and many times, death). You can imagine the travel ramifications of a large explosive eruption from Hekla—we saw that during the 2010 eruption of Eyjafjallajökull. Hekla has produced some large fissure eruptions as well, with abundant basaltic lava flows, much like what we saw from the Holuhraun eruption in 2014-15.

Now, I’m not saying that Dr. Einarsson is wrong to be point out what he thinks the threat of Hekla right now might be, but without official world from the IMO or emergency management agencies in Iceland, I worry that these statements could be jumping the gun (if Dr. Einarsson was quoted correctly). One of the biggest challenges for volcano monitoring and mitigation is getting people to believe the threat when it presents itself. Too many false alarms, even if they aren’t coming from the official monitoring and management agencies, can make people feel like they can’t trust officials (see: L’Aquila earthquake in Italy). I hope that the IMO releases a statement soon in response to what Dr. Einarsson said so we can know what might be happening at Hekla. Until then, you can watch Hekla on its webcam.
