In the last 24 hours, three earthquakes were recorded in the Kverkfjöll system, a central volcano with a powerful geothermal area, and activity remains within normal levels for this region. The increase consists mainly of scattered background activity rather than swarms, and land uplift of 21 mm/year is consistent with the decadal average. Activity resembles the period around March 16, 2026, though results are automatic preliminary findings. Further details on trends and uplift are available below.

In the last 24 hours, one earthquake was recorded in the Kverkfjöll system, a central volcano with a powerful geothermal area, and activity remains similar to the past week. Seismicity is within normal levels for this region and is characterized by distributed background activity rather than swarms. Land uplift is measured at approximately 52 mm/year, which is faster than the decadal average of 22 mm/year, although GNSS data are several weeks old. These automatic preliminary results most closely resemble the period around March 22, 2025, and further data can be viewed below.

In the last 24 hours, two earthquakes were recorded at Kverkfjöll, a central volcano in northern Vatnajökull, indicating increased distributed background activity rather than a swarm. Seismicity remains within normal levels for this area and resembles the period around March 22, 2025, while uplift is currently faster than the decadal average although GNSS data are several weeks old. These automatic preliminary results show the largest event was M0.0 with a cumulative magnitude of Mw 0.2, and further details on trends and uplift are available below.
