Ground uplift and magma accumulation continue beneath Svartsengi

3.7.2026

  • Uplift beneath Svartsengi continues at a steady rate
  • Continued slow magma accumulation, likely ending in a new dike intrusion and possibly an eruption remains the most likely scenario
  • Hazard assessment unchanged, validity extended until 30 September

Ground deformation

Magma accumulation and ground uplift continue beneath Svartsengi. The average rate of magma accumulation over the past few weeks has remained steady.

The most likely scenario remains continued slow magma accumulation, eventually leading to a new dike intrusion and possibly a volcanic eruption.

Seismic Activity

Earthquake activity along the Sundhnúkur crater row and near Grindavík remains relatively low and is similar to previous weeks. No significant changes in seismic activity have been observed in recent weeks.

Hazard Assessment

The hazard assessment remains unchanged, and its validity has been extended until 30 September.
