Volcanoes are so common in Iceland because of its unique tectonic setting it is located above a mantle plume - a hot, buoyant bit of Earth’s mantle that rises upwards, bringing magma to the surface - and on top of the plate boundary where the North American and Eurasian plates incrementally inch apart. Iceland is home to 34 active volcanoes, averaging one eruption every four years. ![]() Already, along the fissure, ridges of solidified lava have started to form. Lava is steadily erupting between five and ten times faster than the lava that erupted at the start of the 2021 eruption. These earthquakes accompanied ground deformation near the site of last year’s eruption, indicating magma movement toward the surface.Ĭurrently, small lava fountains are erupting from a 300-meter-long (1,000-foot), northeast-southwest trending crack on the northern edge of the 2021 lava flow, according to researchers from the University of Iceland and Icelandic Meteorological Office who surveyed the new eruption. ![]() Roughly 5,000 earthquakes have been detected on the peninsula since July 30, according to the Icelandic Meteorological Office - including a magnitude-5.4 event felt in Reykjavik on July 31. ![]() Credit: Edward MarshallĪfter days of elevated earthquake activity on the Reykjanes Peninsula, Iceland’s Fagradalsfjall volcano began erupting at 1:18 p.m. Volcano scientists are keeping a close eye on this eruption, but only time will tell what will happen.īy Melissa Scruggs, Ph.D., Scruggs, Melissa A., 2022, New eruption at Fagradalsfjall Volcano follows days of seismic swarms, Temblor, Įruption at Fagradasfjall.
