Evidence of a new magma deposit in Reykjanes peninsula, more than 6 000 earthquakes in 3 months, Iceland !!!!

Posted in 2020, Earthquakes with tags , , , , on April 9, 2020 by theboldcorsicanflame


Considerable seismic activity continues at the Reykjanes peninsula, Iceland, with more than 6 000 earthquakes manually checked since the beginning of the year.

According to the Icelandic Met Office (IMO), this is the most intense activity ever recorded in the region since the beginning of digital monitoring in 1991.

Data indicates the activity is affecting all volcanic systems in the Reykjanes peninsula and Reykjanes ridge. In addition, GPS measurements, as well as detailed analysis and model calculations of the available data, now give evidence of a new magma deposit west of the Reykjanes peninsula under Rauðhólar and Sýrfell.

Recent data show that uplift has started again, with the center just west of Mt. Thorbjorn, IMO reported on April 2, 2020. Uplift was measured from January 22, 2020, until the beginning of February and has started up again during the first half of March.

During the first sequence in January-February, the deformation rate was about 3 – 4 mm (0.11 – 0.15 inches) per day with a total of 6 cm (2.3 inches) uplift during the whole period.

In the sequence that is ongoing now, the deformation rate looks to be only half of what it was (or even slower). In total, the uplift is about 7 – 8 cm (2.7 – 3.1 inches) since the end of January.

The Scientific Advisory Board (SAB) who met on March 28 still believes that the most likely explanation of the uplift is a magma intrusion where the magma is ‘forcing’ its way horizontally between the stratum in the crust and forming a thin sill at about 3 to 4 km (1.8 – 2.5 miles) depth. The magma intrusion causes a considerable amount of earthquakes in the area north of Grindavík. Their next meeting is scheduled for April 8.

A model of the ongoing magma intrusion shows that fissures can open in the uppermost layer of the crust, at 1 – 2 km (0.62 – 1.24 miles), because of the tensional stress induced by the uplift itself. This change in the crustal stress might lead to more earthquakes related to injection at boreholes, which was not common before in the area, IMO said.

The work procedure for the injections will be reviewed in collaboration with HS-Orka and discussion will be taken on how is the best way to monitor the earthquakes likely due to these changes, it added.

On Saturday, March 28, an earthquake swarm occurred in Eldey, indicating that the activity is affecting all volcanic systems in the peninsula and the ridge, eg. from Eldey all the way to Krýsuvík.

The interpretation of these events is still uncertain, but there are indications that a common underlying process is the cause of the activation of such a widespread area in such a short timeframe.

However, the Reykjanes peninsula and the Reykjanes ridge are composed of plate boundaries. Also, the Eldey, Reykjanes, Svartsengi and Krýsuvík volcanic systems lie right across the boundaries.

Because of the activity ongoing in the area, the SAB believes that it is extremely important to monitor and investigate the ongoing activity in the Reykjanes peninsula as a whole, and compare this activity with older events in the area to try to decipher the reasons and identify possible developments.

In addition, GPS measurements, as well as detailed analysis and model calculations of the available data, now give evidence of a new magma deposit west of the Reykjanes peninsula under Rauðhólar and Sýrfell.

“The data we have processed indicates that the magma insertion has taken place from mid-February until the first week of March. This picture was better explained when we got data from the University’s GPS measurements, which are not directly related to our monitoring system — meaning that we did not detect this until now,” says Kristín Jónsdóttir, Group Director of Nature Conservation at the Icelandic Meteorological Office.

A model places the magma insert at a depth of about 8 – 13 km (5 – 8 miles), which is probably at the bottom of the Earth’s crust at considerably more depth than the two magma deposits at Thorbjörn.

“This magma deposit under Sýrfell is the third magma deposit we report on the Reykjanes peninsula since the turn of the year. The presence of this magma insert supports the Resolution of the Swedish Civil Defense Council that it is necessary to look at the activity in the Reykjanes peninsula comprehensively, and not only from the local activity around Svartsengi and Reykjanes,” Kristín said.

Japan is rattled by 5.2-magnitude earthquake near Fukushima

Posted in 2020, Earthquakes with tags on February 14, 2020 by theboldcorsicanflame


The quake struck just over 50 miles from the city of Fukushima where the nuclear disaster occurred in 2011.

Witnesses said they had felt a 10-second long shake during the tremor at around 7.30pm local time.

The US Geological Survey said today’s earthquake had struck at a depth of around 50 miles under the sea.

One witness told earthquake monitoring service EMSC that the quake produced a ‘weak but long shake’ lasting about 10 seconds.

Another said their heater had moved around on its four wheels while making a sound.

Officials in Fukushima prefecture warned residents that there could be aftershocks and directed them to official public safety advice.

There were eight events and five explosions at Minamidake crater from June 4 to 11. Crater incandescence was occasionally visible at night. Ash plumes rose up to 2 km (1.2 miles) above the crater rim, except during an event at 11:35 JST on June 10 which produced a plume that rose 3.5 km (2.1 miles). Tephra was ejected as far as 1.3 km (0.8 miles) from the crater between June 8 and 11.

The Japan Meteorological Agency maintains the alert level at 3 of 5 since February 5, 2016.

Iceland: Bardarbunga is rumbling again. 4 earthquakes have been detected in the surrounding area

Posted in 2017, Earthquakes, Uncategorized with tags , , on November 2, 2017 by theboldcorsicanflame



Bardarbunga is rumbling again. Iceland’s biggest volcano has been on the verge of erupting for a good few years now, but over the past few days, four earthquakes have been detected in the surrounding area.

While this Earth shimmying might seem concerning, they are more indicative of what is happening beneath the ground, and won’t themselves cause the volcano to erupt. For now, there isn’t any cause for immediate concern.

The experts monitoring the mountain, which is the second-highest peak in Iceland and last erupted in 2014, still predict that it could be up to another few years before the volcano spews its magma over the Nordic nation.

Some are concerned that if and when this happens, there could be a repeat of the infamous 2010 Icelandic eruption. The ash cloud produced by the wonderfully named Eyjafjallajokull, which is estimated to have been around 250 million cubic meters (8.8 billion cubic feet), wreaked havoc across much of Europe. For five days, much of the airspace was shut down, as there were concerns that the ash could seriously damage the engines of any planes caught flying through it.

This created what is thought to have been the largest disruption of air travel since World War II. Earthquakes around active volcanoes are a common occurrence. As the magma below the surface migrates into the chamber of the volcano, the movement of such massive amounts of molten rock inevitably cause the ground to wobble a bit. From this perspective then, the earthquakes are not the cause of the eruption, but instead seen as a symptom of the impending blast that could occur at any point within years.

When it comes to Iceland, there are always going to be reports that an eruption is imminent. This is because Iceland is straddling the fault line between the American and Eurasian plates, thus making it a particular hotspot. It will always have volcanoes, as magma snakes its way through the fissure and eventually bursts through the surface, but few actually do as much damage as Eyjafjallajokull. If the volcano happens to be sitting under a glacier, than the chances are heightened, but even so, one study has already suggested that such an event is unlikely to happen for a few decades……(so they say…)

Mexicans are in EXTREME DANGER of another, even larger earthquake than the massive M7.1 which struck south of Mexico City earlier this week.

Roads in the area have begun OUT-GASSING . . . They appear to be Breathing . . . meaning the earth below is being squeezed so hard, it is venting gas from deep in the earth.

4 of Iceland’s main volcanoes: katla, Hekla, Grímsvötn and Bárðarbunga are all preparing for eruption

According to geophysicist Páll Einarsson, four of Iceland’s volcanoes are showing increased amounts of activity in preparation for another eruption. 

Katla is the most active that it’s ever been in four decades. “Katla has been unrestful since this autumn.”

The other volcanoes showing increased activity are Hekla, Grímsvötn and Bárðarbunga. 




Iceland is a volcanic island sitting on top of the Atlantic ridge and Icelanders are constantly reminded of that. Yesterday the farmers and summer cottage owners in the inland of south Iceland clearly felt a 4.5 magnitude earthquake originated in the domain of an active volcano.

One farmer in the area described the earthquake as if a truck hit her farm to a RUV reporter, the family clearly felt a single strong impact and they ran straight to the window to check on their neighbour, the volcano named Hekla.

According to measurements the current pressure in the magma chambers underneath Hekla volcano is greater than it was leading up to the last two eruptions in 1991 and 2000. The pressure has been mounting for quite some time and there have been numerous predictions and speculations about a looming eruption.

The pressure clearly points to the volcano being ready to erupt but it’s hard to say what the tipping point will be. The earthquake yesterday doesn’t have a direct link to the pressure under Hekla Volcano but evidently something is brewing under the crust of south Iceland judging by the pressure in the magma chamber and the number of tremors and earthquakes taking place there in the past months.
