Related tremors have been noticed forward of volcanic eruptions up to now, and the Icelandic Meteorological Workplace mentioned that magma actions have been a probable trigger for the persevering with exercise. The company has warned that an eruption may happen inside days or perhaps weeks.
“The 2 tectonic plates are transferring away from one another, and that motion has created the situations for magma to return to the floor,” mentioned Freysteinn Sigmundsson, a analysis professor of geophysics on the College of Iceland.
Dr. Einarsson mentioned that out of the 5 volcanoes within the Reykjanes space, magma motion had been noticed close to not less than three of them because the seismic episode started in December 2019. “We could also be coming into a brand new lively interval within the peninsula,” he added. “There appears to be meals for some eruption.”
Iceland has about 30 lively volcanoes, however volcanologists say an eruption in Reykjanes received’t threaten inhabited areas on the peninsula. “We’re speaking about an effusive eruption, fairly than explosive,” mentioned Dr. Sigmundsson, explaining that the lava would doubtless bubble out with little explosive power.
He added that any exercise is unlikely to be as disruptive because the eruption that occurred in 2010, when one other volcano in Iceland launched a plume of ash so huge that it brought about one of the crucial important air-traffic interruptions in many years, stranding thousands and thousands of passengers in Europe, some for weeks.
The meteorological workplace mentioned the volcanic exercise may happen close to Fagradalsfjall, 20 miles south of Reykjavik, or close to the Keilir mountain shut by. Lots of of volcano fanatics have been riveted to reside cameras within the space, and a web site asking “Has there been an eruption but?” has stored them up-to-date. (It nonetheless learn “Nei” — No — as of Thursday afternoon, however a playlist on the web site helped with the wait.)
The meteorological workplace mentioned that amongst potential situations, the continued seismic actions may lower within the coming days or perhaps weeks, however the peninsula may additionally face extra earthquakes, as much as magnitude 6.5.
