Southwest Iceland is at present experiencing a “swarm” of seismic exercise, with greater than 20,000 earthquakes recorded since February 24, in accordance with the the Icelandic Meteorological Office. The workplace stated magma actions are seemingly the reason for the present surge on the Reykjanes Peninsula, elevating fears of a volcanic eruption.
There have been greater than 3,100 earthquakes on the peninsula previously 48 hours alone, in accordance with the workplace. At least 63 of them had a magnitude of three or larger. A magnitude 3 earthquake will be felt, however hardly ever causes harm; because the quantity will increase, the earthquakes turn out to be extra harmful. Similar bursts of seismic exercise within the nation have beforehand precipitated volcanic eruptions, the workplace stated.
2/3 Since then two earthquakes over M5.0 detected. Occurred on Feb. twenty seventh and March 1st. Over 20000 earthquakes have been detected within the space since exercise began. At 19:14 an M4.2 earthquake was detected 2 km N of Grindavík. It was felt within the Grindavík and within the capital space— Icelandic Meteorological Office – IMO (@Vedurstofan) March 5, 2021
The aviation shade code for the Reykjanes Peninsula is at an orange degree, that means there may be “heightened unrest” and that there’s an “elevated chance of eruption,” in accordance with the workplace.
The authorities of Iceland stated on its web site Thursday that there was a volcanic tremor pulse close to Mt. Keilir, which is situated on the peninsula, on Wednesday.
Earlier right this moment a tremor pulse was detected south of Mt Keilir, within the Reykjanes Peninsula, SW Iceland. No eruption has but been detected however as a consequence of dangers associated to volcanic exercise, all site visitors close to Keilir and Mt Fagradalsfjall is prohibited, together with drone flights.— Almannavarnir (@almannavarnir) March 3, 2021
While the federal government initially stated that this “might result in an imminent volcanic eruption,” the Scientific Council for Civil Protection stated on Friday that information from the previous 24 hours “don’t give any indication that magma is shifting nearer to the floor.” “During this era, there may be not a excessive likelihood of an eruption,” the council stated, whereas noting that “the state of affairs can change quickly.”
If an eruption does happen, information reveals that it’ll seemingly be within the space between Fagradalsfjall and Keilir. The authorities stated on its web site that if there may be an eruption, it is anticipated to be a “comparatively” small fissure eruption lasting up to a couple weeks. These varieties of eruptions, the federal government stated, entail a “sluggish circulate” of lava somewhat than giant explosions or important ash.The authorities has stated there may be “very low” danger to populated areas and significant infrastructure, and Prime Minister Katrín Jakobsdóttir stated the nation is “extraordinarily nicely ready.” “Iceland has extremely skilled, educated and skilled professionals on this space,” Jakobsdóttir stated in an announcement. “Most essential, the Icelandic public is used to dealing calmly with many various kinds of pure occasions associated to the climate or geology.”
The final main volcanic eruption in southern Iceland occurred in 2010. It was the primary time in almost 200 years the Eyjafjallajökull volcano erupted, and lots of of individuals had been pressured to evacuate the realm. Similar to the present occasion, the Eyjafjallajökull eruption occurred after a month full of 1000’s of small earthquakes. The authorities stated that an eruption of Mt. Keilir “won’t produce giant fumes which have the potential to disrupt worldwide aviation,” though it will quickly disrupt air site visitors. On Wednesday, all drone flights within the space had been banned in case of an eruption.
