Reykjanes volcano (Reykjanes Peninsula) - Smithsonian / USGS Weekly Volcanic Activity Report for 17 April-23 April 2024 (Continuing Activity)

IMO reported that the cone just E of Sundhnúk and along the fissure within the Reykanes volcanic system continued to erupt lava during 15-23 April. Gas emissions continued to drift downwind and residents were advised to monitor air quality. Lava flowed a short distance from the crater mostly S and the flows thickened near the crater.
Lava tubes in an area about 1 km SE transported lava to an active flow field N of Hagafell; webcam images showed inflation of the part of the flow field located along the barriers E of Grindavík during 18-23 April. Inflation from magma accumulation beneath Svartsengi was first detected at the beginning of April and continued at a steady rate based on modeling of GPS and satellite data.



The average effusion rate was 3-4 cubic meters per second during 1-15 April. Results from a 15 April overflight where scientists acquired images for mapping showed that the lava-flow field was an estimated 6.15 square kilometers with an approximate volume of 33.2 (± 0.8) million cubic meters.
