The eruption continues with the lava effusing from the active vent, albeit at reduced activity levels.
Minimal changes have been observed in the southern part of the lava field near the defensive barriers east of Grindavík over the past week.

In the Svartsengi region, the magma accumulation and ground deformation continue steadily, indicating sustained pressure build-up in the magma chamber. Consequently, there remains a possibility of a new dike intrusion from the Svartsengi magma chamber towards the active crater.

The seismic activity has been elevated in and around the eruption zone over the past week, with most earthquakes registering below magnitude 1. These tremors have been primarily clustered north of the current eruption site, between Sundhnúk and Stóra Skógfell, south of Þorbjarnar in the expansive valley near Grindavík, and between Grindavík and the current eruption site.
