Volcanic Eruption

On March 19th, 2021, a volcanic eruption started on the Reykjanes peninsula. Since then, the volcanic site has attracted thousands of visitors. Our tasks include protecting the area and monitoring air quality.

Protecting the Lava

The lava in Geldingadalir is a unique geological monument that we must respect and protect. It is important for visitors to leave no trace after their visit.  

Please do not:

  • throw stones at the lava  
  • make inscriptions or carvings on the lava
  • leave any trash on site

Lavas are under special protection according to art. 61 of the Nature Conservation Act and therefore they must be protected from damages such trampling, stones, or inscriptions.

Volcanic Gas

During volcanic eruptions gas with effects on human health is released into the atmosphere. These are mainly:

Sulfur Dioxide (SO2)

The most common human health symptoms are irritation in the eyes, throat, and respiratory tract. In high concentrations of SO2 people can experience difficulties in breathing.  

Visitors should monitor the concentration of SO2 in the atmosphere. Information and measurements are available on the website for ambient air quality which the Environmental Agency of Iceland operates.  

Carbon Dioxide (CO2) and Carbon Monoxide (CO)

When this colorless, odorless gas is emitted from volcanoes it can flow into low-lying areas where it can reach much higher concentrations causing serious risk. This can happen in stable atmospheric conditions.

Active Volcanoes

Even when no activity can be seen in the crater the eruption is still active. Underneath the hardened top layer of lava burning hot lava can be flowing. The top layer can easily break when stepped on.  

Please do not walk on the lava - it is hard to predict where the lava might open or break.  

Walking on the lava can also harm geological monuments

Park Rangers

The Environmental Protection Agency’s rangers work on the hiking trail of the eruption area and inform and educate visitors on how to enjoy the beauty of nature in harmony with nature conservation in a safe way.

As Geldingadalir is classified as a dangerous area, the Icelandic Civil Protection and the local rescue team also operate in the area.


General Travel Safety  

Iceland offers the traveler an adventure in a spectacular landscape of stunning natural beauty. However, it can also be a harsh and inhospitable environment and it is essential to be cautious and well prepared when travelling, on the volcanic site and elsewhere.
