Geological activity raises concerns of potential eruption in Öskja, Iceland

Recent geological activity in Öskja, a volcanic region in Iceland, suggests that the area is experiencing significant inflation and magma accumulation, which could signal a potential eruption in the future. Over the past three years, the ground has risen nearly one meter in certain areas, prompting increased monitoring from geological experts.

While there is clear evidence of land uplift, seismic activity has not dramatically increased, nor have there been any notable changes in the geothermal systems in the region. Experts indicate that magma is likely flowing at depths of 3 to 5 kilometers, which is consistent with typical signs of surface inflation reported in other volcanic areas.

Benedikt Gunnar Ófeigsson, a specialist in volcanic measurements, noted that while there are indicators of renewed volcanic activity, it is challenging to predict the timing or nature of a potential eruption. He emphasized that while the volcano is active and could erupt again, it’s difficult to ascertain if this might happen in the next year or in five years.

The last confirmed eruption in Öskja occurred in 1961, and experts acknowledge that historical data on land changes prior to this eruption is limited. As a result, it remains uncertain how much additional uplift and magma accumulation may be needed before an eruption occurs. Current monitoring efforts continue to observe any changes in seismic signals and ground deformation, keeping public safety and awareness a priority in this active volcanic region.
