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.

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.

In the Icelandic fishing industry there is a clear focus on value added production where a “quantity mentality” has been replaced with a “value mentality”. This has led to raw material that was previously considered “fish waste” and discarded, such as fish livers and fish roes being utilized to the extent of what is economically sensible. Today fish viscera, fish heads, frames from filleting, fish bones, swim-bladders and fish skin are all utilized to an increasing extent. Specialized products, such as fish enzymes, chitin (from shrimp shells), fish leather for fashion items as well as specialized omega fish oils are all part of this development. The aim is clear, that all biomaterial coming from the sea is used to its full extent. At this place you can see where heads are being dried before further processing.
