The Swedish Uppsala University Media Office announced that the analysis of geologists and seismologists of the eruption of the Fagradalsfjall volcano in Iceland showed that it will erupt again in the coming decades.
“We studied the geochemical processes associated with recent volcanic eruptions in Iceland. Comparing our results with historical data shows that Iceland should prepare for continued volcanic eruptions on the Reykjanes Peninsula in the coming years or even decades,” says Professor Valentin Trolle.
Scientists reached this conclusion from their study of the eruption of the Fagradalsfjall volcano, which woke up in March 2021 after nearly eight hundred years of hibernation. Before its eruption, seismologists recorded a large number of small earthquakes.
Geologists and seismologists decided to conduct a detailed study of the changes in the surface of the volcano and the volcanoes of the so-called Reykjanes Belt. During this, the Sundhundur volcano erupted, forcing scientists to analyze the history of volcanic eruptions and the current state of volcanic activity centers.
Isotope analysis by the researchers of lava samples from Fagradalsfjall and Sundhånøkur volcanoes showed that they are fed by the same magma reservoir, which lies beneath the Reykjanes Peninsula, at a depth of about 9-12 km, as well as by magma flows from deep in the mantle.
According to researchers, these factors indicate that volcanic eruptions on the Reykjanes Peninsula will continue in the coming years or decades. Therefore, the authorities must take the necessary measures to confront them.
