Information about the current condition of the crater after the eruption in Fagradalsfjall in southwest Iceland was provided by mbl.is Þorvaldur Þórðarson, a geologist at the Institute of Geosciences at the University of Iceland. He explained that most of the lava flowing out of the crater now flows under the lava crust and is not visible on the surface.
It looks like this process will form a shield volcano. However, this can only be confirmed when a large lava lake forms at the crater.
“This is just such a lava lake that is being built. Lava flows out of it constantly in different directions. The lake is fed by a stream of lava from the crater, and solidified lava collects around the crater. This is how the shape of the shield is created “ Says Þorvaldur.
Otti Rafn Sigmarsson, who works with the Þorbjörn rescue team in Grindavík, states that visitors to the site can no longer get as close to the eruption as before. Even though the eruption is clearly visible, it is not as impressive as it used to be. He also notes that the fires near the edge of the lava stream have stopped.
