The Meteorological Office released two reports today on the long-term lava flow hazard assessment for the Reykjanes Peninsula, advancing its comprehensive review of volcanic risks across the entire region. 

The project launched in early 2024, with four reports published so far and completion expected in 2027. Four reports covering fissure hazards, two more addressing lava flows, and one focused on earthquakes will join the series this year. Assessments detailing tephra fall, gas pollution, and groundwater contamination are scheduled for next year. Consolidating a complete volcanic hazard assessment for an area spanning seven volcanic systems, 16 municipalities, and extensive critical infrastructure is a monumental, globally unprecedented undertaking.

Primary goal is to reduce damage, with a focus on infrastructure

Based on the region's eruptive history, this evaluation identifies potential eruption source zones and areas vulnerable to lava flows. The main objective is to reduce damage, particularly to infrastructure, and the findings offer crucial data for settlement planning and land use decisions.

The report details specific zones exposed to lava flow hazards. These findings will assist professionals in settlement planning, infrastructure operators, and emergency responders updating their response plans.

The reports will inform future planning

The results reinforce existing knowledge and align with current understandings of where lava flows threaten settlements and infrastructure in the capital area. While it avoids defining "acceptable risk" for local residents or businesses, the long-term hazard assessment lays the groundwork for those crucial conversations and decisions. Local governments will use it as a vital tool when planning future settlements and commercial development.

Alongside these publications, the Meteorological Office launched eldfjallava.is, featuring an interactive map viewer for users to explore the findings in greater detail.
