In the last 24 hours, 6 earthquakes were measured in the Torfajökull system, which is the largest rhyolite volcano in Iceland. Activity has been increasing recently, and is now well above the weekly average (4 earthquakes per day) and monthly average (2 earthquakes per day). This is slightly more activity than usual for this area, and is most similar to a period around May 9, 2019. The largest earthquake in the last 48 hours was M1.0 and the cumulative magnitude was Mw 1.3. Results are automatic preliminary results.

In the last 24 hours, 4 earthquakes were measured in the Torfajökull system, which is the largest rhyolite volcano in Iceland. The activity is similar to the past week but slightly higher than usual for this area, with a β-value of 2.1. The largest earthquake was M1.0, and the cumulative magnitude of earthquakes in the last 48 hours was Mw 1.2. The activity is mostly diffuse background seismicity rather than swarms and is most similar to a period around May 11, 2019. These are automatic preliminary results.

In the last 24 hours, 4 earthquakes were measured at Torfajökull, the largest rhyolite volcano in Iceland. Activity is similar to the past week, but above the average of the last month. The largest earthquake was M1.0 and the cumulative moment of earthquakes in the last 48 hours was Mw 1.1. The seismic activity is within what is normal for this area and is characterized by diffuse background activity rather than swarms. Results are automatic preliminary results.

Over the last 24 hours, seismic activity in the Torfajökull caldera, the country's largest rhyolite volcano with an extensive geothermal area, has been slightly higher than usual. There were 4 earthquakes detected during this period, indicating that activity is increasing compared to the weekly average, characterized by scattered background activity rather than swarms as 87% of events over the last seven days were independent. The largest earthquake in the last 48 hours was magnitude 1.6 (M1.6) with a cumulative moment magnitude of Mw 1.7, and the current activity most closely resembles the period around September 21, 2018. All results are automatic preliminary data with unreliable depth calculations, and further maps and trend data can be found lower on the page.

Over the last 24 hours, 8 earthquakes were detected in the Torfajökull caldera, the country's largest rhyolite volcano, which represents slightly more activity than usual for this area where the average is 0.9 earthquakes per day. This increase is characterized by scattered background activity rather than swarms, with 89% of events over the last 7 days being independent background events, and the activity most closely resembles the period around October 19, 2025. The largest earthquake in the last 48 hours was magnitude 1.1, and the cumulative magnitude for that period was 1.5, although these results are unverified automatic preliminary data with unreliable depth measurements.

There were 6 earthquakes detected in the last 24 hours, which is well above the weekly average, with the activity characterized by scattered background activity rather than swarms, as 89% of the events over the last 7 days were independent. The largest earthquake in the last 48 hours was magnitude 1.1 and the cumulative magnitude for the period was 1.5, with these being automatic preliminary results where depth is unreliable. The current activity most closely resembles the period around October 18, 2025, when 14 earthquakes were detected, and further information and development maps can be found below on this page.

In the last 24 hours, five earthquakes were recorded in the Torfajökull system, Iceland's largest rhyolitic volcano, indicating distributed background activity rather than a swarm. Seismicity is increasing compared to the weekly average but remains within normal levels for this area, with a cumulative magnitude of Mw 1.8 over the past 48 hours. These automatic preliminary results resemble the period around July 5, 2026, and further details on trends are available below.

In the last 24 hours, six earthquakes were recorded in the Torfajökull system, representing an increase above the weekly average while remaining within normal levels for this area. Seismicity is characterized by distributed background activity rather than swarms, with the largest event in the past 48 hours being M1.5 and a cumulative magnitude of Mw 1.6. These are automatic preliminary results, and current activity most closely resembles the period around July 10, 2026. Further details on trends and maps are available below.

In the last 24 hours, five earthquakes were recorded in the Torfajökull system, Iceland's largest rhyolite volcano, indicating increasing activity as the count exceeds the weekly average. This distributed background activity remains within normal levels for the area and most closely resembles the period around July 7, 2026. The largest earthquake in the past 48 hours was magnitude M1.5 with a cumulative moment of Mw 1.5. These results are automatic preliminary findings, and further details are available below.

Over the last 24 hours, seismic activity in the Torfajökull caldera, the country's largest rhyolite volcano with an extensive geothermal area, has been slightly higher than usual. There were 4 earthquakes detected in the area, indicating increased activity compared to the weekly rate, with this activity consisting mostly of scattered background events rather than swarms, closely resembling the period around July 8, 2026. The largest earthquake in the last 48 hours was magnitude M1.7, and the cumulative magnitude for this period was Mw 1.8. Please note that these are automatic preliminary results and depth estimates are unreliable, but further details and maps are available below.

Over the last 24 hours, activity in the Torfajökull volcano, the country's largest rhyolite caldera with an extensive geothermal area, has been increasing and is somewhat higher than usual for this area. There were 5 earthquakes 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 90% of events over the last 7 days were independent. The largest earthquake in the last 48 hours was magnitude 1.7 and the cumulative magnitude for the period was 1.8, although these results are unverified automatic preliminary data with unreliable depth measurements. The current activity most closely resembles the period around 8 July 2026, and further information and maps can be found below.

Over the last 24 hours, seismic activity in Torfajökull, the country's largest rhyolite volcano with an extensive geothermal area, has been increasing and is somewhat higher than usual for this area. There were 4 earthquakes detected in the last 24 hours, which is well above the weekly rate, with the activity consisting mostly of scattered background activity (86% independent events) rather than swarms. The largest earthquake was magnitude 1.4 (M1.4) with a cumulative moment magnitude of 1.5 (Mw), though these results are automatic preliminary findings and their depth is unreliable. This increase most closely resembles the period around May 20, 2025, when 8 earthquakes were detected, and further details and trend maps can be found lower on the page.

In the last 24 hours, three earthquakes were recorded in Torfajökull, Iceland's largest rhyolitic volcanic system, indicating that activity is currently decreasing compared to the weekly average. Despite this decline, the state remains unusual for the area with an increased b-value (β=2.4) and distributed background seismicity rather than distinct swarms. The cumulative magnitude over the past 48 hours is Mw 1.9, and these results are automatic preliminary findings. Activity most closely resembles the period around April 8, 2026, and further details are available below.

In the last 24 hours, 10 earthquakes were recorded in Torfajökull, indicating activity considerably higher than usual for this area and similar to the past week. The activity is characterized by distributed background seismicity rather than swarms and most closely resembles the period around April 8, 2026. The largest earthquake was M1.4 with a cumulative magnitude of Mw 1.9 over the last 48 hours; results are automatic preliminary results. Further charts and maps are available below.

In the last 24 hours, 13 earthquakes were recorded at Torfajökull, indicating significantly higher activity than usual for this area and suggesting an increase. The activity has been distributed background seismicity rather than swarms and most closely resembles the period around April 8, 2025, though these are automatic preliminary results. The largest earthquake was M1.5 and the cumulative magnitude over the last 48 hours was Mw 1.8. Further details on trends and measurements can be found lower on the page.
