Öræfajökull

Over the last 24 hours, no earthquakes were detected in Öræfajökull, Iceland's highest volcano, and the seismic activity is decreasing and remains within what is considered normal for this area. Geodetic measurements at station FAGC show land uplift of approximately 735 mm per year, which is faster than the decadal average, though these GNSS data are several weeks old and short-term trends remain uncertain. The current activity most closely resembles the period around January 7, 2025, and all results are automatic preliminary findings with unreliable earthquake depths. Further details and maps of the area can be found below. (status from 2026-07-18 04:35 UTC)

Iceland's highest volcano (Hvannadalshnjúkur). The 1362 eruption was one of the deadliest in the country's history and destroyed the district of Litla-Hérað; erupted again in 1727. Rare but very powerful. (overview — more at vedur.is) · circle on the map = rough outline of the system (radius).

Over the last 24 hours, no earthquakes have been detected in Öræfajökull, Iceland's highest volcano, and the seismic activity is decreasing and currently below the weekly average. This activity is considered completely normal for this area, with the largest earthquake in the last 48 hours measuring magnitude M-0.6 and the cumulative magnitude for the same period being Mw -0.6. Geodetic measurements show land uplift of approximately 735 mm per year according to several weeks old GNSS data, which is faster than the decadal average of 21 mm per year, although uncertainty remains over such a short period. The current activity most closely resembles the period around April 17, 2025, but it should be noted that all results are automatic preliminary results with unreliable depth measurements. Maps and further details on the development can be found lower on this page.

Over the last 24 hours, 1 earthquake was detected in Öræfajökull, Iceland's highest volcano, indicating that seismic activity is increasing as the last 24 hours are well above the weekly rate. This activity is, however, within what is considered normal for this area and most closely resembles the period around April 17, 2025, with all results being automatic preliminary findings with unreliable depth measurements. The largest earthquake was of magnitude M-0.6, and the cumulative magnitude over the last 48 hours was Mw -0.6. GNSS measurements from a few weeks ago show land rising at approximately 735 mm per year, which is faster than the decadal average of 21 mm per year.

In the last 24 hours, five earthquakes were recorded at Öræfajökull, Iceland's highest volcano, indicating increased activity compared to the weekly average. This frequency is higher than usual for the area and most closely resembles the period around October 5, 2024. The largest earthquake was magnitude M1.4, and these are automatic preliminary results. Further details on trends can be found below.

In the last 24 hours, four earthquakes were recorded at Öræfajökull, Iceland's highest volcano, indicating increasing activity that remains within normal levels for this area. The largest event was magnitude M1.4 with a cumulative moment of Mw 1.4 over the past 48 hours, based on automatic preliminary results. Current activity most closely resembles the period around October 6, 2024, in terms of earthquake count. Further details on trends and measurements are available below.
