Since significant seismic activity on Reykjanes resumed on July 4, some 4,700 quakes have been recorded. The largest quake so far recorded, M4.8, occurred yesterday morning, July 5. Additionally, 13 earthquakes above M4 have been recorded, with a slight decrease in seismic activity since last night.
Geologists have indicated that the current earthquake swarm on the Reykjanes peninsula suggests a more aggressive magma intrusion than in 2021 and 2022. Land uplift on the Reykjanes peninsula is currently measured at 3cm. While the total uplift is similar to previous eruptions, it has been measured across a larger area on the peninsula. The previous 2021 and 2022 Fagradalsfjall eruptions saw more localised land uplift.
