Volcanic activity escalating in part of Iceland that has not erupted for 800 years

Scientists warn it could cause disruption for centuries to come.

Since 21 January, the Reykjanes peninsula south-west of Iceland’s capital, Reykjavik, has experienced more than 8,000 earthquakes and about 10cm of land uplift due to magma intrusions underground.

“It seems that after being relatively inactive for many centuries, this region is waking up,” said volcanologist Dave McGarvie.

Reykjanes peninsula’s last active period started in the 10th century and lasted until the 13th. Situated only nine miles (15km) from Iceland’s international airport, when activity in this region gets going it appears to splutter on and off for up to 300 years, producing eruptive episodes (locally known as “fires”) lasting a few decades. Long thin cracks (fissures) extend up to five miles (8km), producing fountains of lava, usually without large amounts of ash or explosive activity.

“People on the Reykjanes peninsula, and their descendants for several generations, may have to be on their guard and ready to evacuate every so often,” said McGarvie.

  1. The Icelandic Prime Ministers have for years been warning Europe about the consequences of Icelandic Volcanic eruptions.
    Hekla Volcano will create particular havoc in the event of an eruption. It’ll erupt sometime this century. A large eruption will have major consequences for Europe.
    The Icelandic leaders have been warning all European leaders.
    Those leaders haven’t taken any notice.
    That Eyjafjallajökull eruption, Iceland – April/May 2010 caused a major disruption around Europe – That was a small eruption.

    Similar. Health experts have been warning about the consequences of a worldwide pandemic for years. When one struck in February, governments worldwide were un-prepared.

      • see MedCram.notes by a pulmonologist working with actual patients and instructing medical students in evening. Quite difficult lectures if you were not biologically instructed at school. Dr Seheult on You tube or on MedCram web page.

    • And the Winter of 2010 Bad {LOTS of Snow and Sharp Temp Drops} Here in England so to Me Proves that it was the Volcano caused it…..

    The period 800 years ago looks to me to be a Gleissberg period of solar activity with several Sun cycles orbiting the Solar System BarryCentre via shallow Trefoil orbits much as the period of cycles SC10 to 13 or 1900 to 1930. This shows solar activity sliding from the medieval warm period into the depths of the WOLF grand solar minimum and further Icelandic volcanic activity.

  3. The Guardian is way behind on reporting the activity under the Reykjanes ridge. Jón Frímann Jónsson has been posting updates for many weeks about Reykjanes & other volcanoes. During the night of 20-April 2020 a magnitude Mw4,8 earthquake took place in Bárðarbunga volcano. This activity is normal and this is the strongest earthquake in Bárðarbunga volcano since January 2020 when a magnitude Mw4,8 earthquake took place. He’s also asking for contributions to support his work.

  4. The problem is obvious. Iceland has two volcano related problems. One is that it is on a oceanic rift fault that spreads about an inch per year and secondly it also has a hot spot like Yellowstone locked on that rift fault which magnifies the availability of heat and magma. The size of the hot spot is almost as big as the island so don’t count on the volcanic systems going extinct anytime soon….The only limiting factors are gas pressure and the spreading of the plates.

  5. This is interesting. Iceland is, of course, on the Mid-Atlantic Ridge , like the Azores. I’ve been to Iceland and walked in the Mid-Atlantic ridge area, with N American plate on the west side and European plate on the east side.There is a basalt cliff showing the edge of the American tectonic plate.
    Iceland is slowly growing in area, of course. It is thought that a major volcanic eruption in the 18th century caused the Little Ice Age as dust from the huge eruption blocked out the sun and caused global cooling. Europe was badly affected.
    Any thoughts on that?
