There has been a clear increase in seismic activity near the Sundhnúkur crater row on a weekly basis, except for the last week of February, which was likely due to weather conditions. The seismic station that previously caused measurement disturbances has been corrected. Earthquake activity continues in the same location as in the lead-up to previous eruptions—between Sundhnúkur and Stóra-Skógfell—where magma first reached the surface in six of the seven eruptions since December 2023.

The data reveals that the lava field that was formed during the last eruption (20 November to 9 December) had a total volume of 49,3 million cubic meters erupted and covered an area of 9,0 square kilometers. The thickest part of the lava field was around the craters and close to the barriers by the Blue Lagoon but the average thickness of the lava was 5,5 meters.

Seismic activity in the Sundhnúkar crater row remains relatively low. A few earthquakes have been recorded daily, most of them located between Stóra-Skógfell and Sýlingarfell. On some days in the past week, bad weather has affected the sensitivity of the seismic monitoring system, potentially obstructing the detection of the smallest earthquakes.

The Icelandic Met Office has updated the hazard map for the eruption site. The vicinity of the eruption area is still dangerous. High temperatures characterize the lava field. The solidified crust can be very thin in places with very hot and molten lava underneath. The edges of the new lava field are unstable and large chunks of lava can fall sudden. As a result of past activity there are fractures in the area that pose danger. The new lava continues degassing and hazardous gases can collect in depressions
