As of August 18, 2025: Iceland experienced its twelfth volcanic eruption in just over four years. On the sparsely populated Reykjanes Peninsula, southwest of Reykjavik, the earth opened up again on Wednesday, July 16. Since Tuesday, August 5, no more lava has been escaping from the eruption fissure located approximately seven kilometers northeast of Grindavik. Volcanologists believe it is highly likely that the eruption has ended for the time being. The temporarily closed campsite in the town of Grindavik is now freely accessible again.

Really impressive in the old lava fields

The fissure is surrounded by ancient lava flows that have cooled and solidified, forming a rugged, rocky landscape. Despite the volcanic terrain, the area is home to a surprising amount of vegetation adapted to lava soil, as well as birds and other animals typical of Iceland.

It is a unique geological feature located near Reykjavik in Iceland. It is a canyon formed by a volcanic fissure in the Hafnarfjörður region on the Reykjanes Peninsula. It is a fascinating place for both its geology and natural beauty. Near Búrfellsgjá is the Búrfell crater, which is an impressive volcanic feature in itself. This crater is almost perfectly shaped and offers a closer look at the volcanic activity that formed the region.
