Projects
Following the seismic activity and volcanic eruptions on the Reykjanes Peninsula.
Verkís played a leading role in a comprehensive ground investigation and hazard mapping programme in Grindavík.
The project formed part of the Icelandic Civil Protection risk assessment process and was carried out in collaboration with ISOR, the Icelandic Road and Coastal Administration, the University of Iceland, and other specialist organisations.
Verkís was responsible for project management and participated in field investigations, mapping, and analysis aimed at identifying ground fissures, subsurface voids, and areas of geotechnical risk. The primary objective was to improve safety for emergency responders, support access to affected areas, and provide a technical basis for future recovery and development efforts.
The investigation revealed seven major fissure zones throughout the town, including extensive subsurface fractures and voids that were not visible at the surface. Some fissures were found to be approximately 80 centimetres wide and 5–6 metres deep, while the largest underground cavities extended to depths of 30 metres and reached widths of up to 5 metres.
The findings provide critical information for infrastructure repairs, urban planning, risk mitigation, and future development in Grindavík. The project established a systematic methodology for investigating and managing new ground movements and created an important technical foundation for the town’s long-term recovery and resilience.

Following the seismic activity and volcanic eruptions on the Reykjanes Peninsula, Grindavík faced unprecedented geotechnical challenges that threatened public safety, critical infrastructure and future recovery efforts. A rapid and systematic assessment was required to identify hidden ground hazards and support informed decision-making.
Verkís led the project management of a comprehensive ground investigation and hazard mapping programme in collaboration with key national organizations. Our specialists carried out field investigations, geotechnical assessments and detailed mapping to identify ground fissures, underground voids and unstable areas, providing essential data for emergency response, infrastructure planning and future development.
The investigation identified seven major fissure zones and previously undetected subsurface cavities, establishing a robust technical foundation for risk mitigation, infrastructure rehabilitation and long-term urban planning. The project has played a critical role in supporting the safe recovery and future resilience of Grindavík in the aftermath of the volcanic events.
