Eyjafjallajökull

No particular signs of unrest in the last 24 hours — 0 earthquakes recorded, within the system's normal range.

Central volcano beneath the namesake glacier. The 2010 eruption produced an ash cloud that disrupted air travel across Europe. Erupts rarely (previously 1821–23). (overview — more at vedur.is) · circle on the map = rough outline of the system (radius).

Over the last 24 hours, seismic activity in Eyjafjallajökull, a central volcano under the glacier of the same name, has been increasing and is currently measured somewhat higher than usual for this area. A total of 4 earthquakes were detected in the last 24 hours, which is well above the weekly rate, with the activity characterized by scattered background activity rather than swarms as 83% of events over the last 7 days were independent. The largest earthquake in the last 48 hours was magnitude M2.1 and the cumulative magnitude for that period was Mw 2.2, while no ground deformation is detected as GNSS data show land subsidence of approximately 25 mm per year. This activity most closely resembles the period around April 12, 2025, but it should be noted that these results are automatic preliminary findings where depth is unreliable. Maps and further details on this development are available below.

Over the last 24 hours, 4 earthquakes have been detected under Eyjafjallajökull, a central volcano under the glacier of the same name, indicating that activity is increasing and is somewhat higher than usual for this area. This increase manifests as diffuse background activity rather than swarms, with 83% of events over the last 7 days being independent background events, and the activity most closely resembles the period around April 12, 2025 as a historical analogue. The largest earthquake in the last 48 hours was magnitude M2.1 and the cumulative seismic moment for that period was Mw 2.2, while GNSS measurements show land subsiding by approximately 25 mm per year. It should be noted that the earthquake results are automatic preliminary results with unreliable depths, but further data and maps can be found lower on this page.

Over the last 24 hours, 3 earthquakes were detected in Eyjafjallajökull, a central volcano under the glacier of the same name, indicating increasing activity and slightly more than usual for this area where the average rate is 0.3 earthquakes per day. This activity, which consists mostly of scattered background activity (83% independent events) rather than swarms, most closely resembles the period around July 8, 2025, when 10 earthquakes were detected. The largest earthquake in the last 48 hours was magnitude M1.2 and the cumulative moment magnitude in the area was Mw 1.3, while GNSS measurements show land subsiding by approximately 24 mm per year. Please note that these results are automatic preliminary results with unreliable depths, but further data and maps can be found lower on this page.

In the last 24 hours, four earthquakes were recorded in the Eyjafjallajökull system, a central volcano under the glacier of the same name, with activity increasing above the usual background level for this area. The increase is mostly due to short-lived swarms rather than distributed background seismicity, as frequency now exceeds the average of 0.3 earthquakes per day. The cumulative magnitude of the largest events in the past 48 hours was Mw 1.1, and GNSS data at STE2 indicates subsidence of approximately 12 mm/year. These automatic preliminary results resemble the period around July 8, 2025, and further details are available below.

In the last 24 hours, three earthquakes were recorded at Eyjafjallajökull, a central volcano under the glacier of the same name, with activity increasing but remaining normal for this area.
