Results of CO2 flux measurements and seismic catalogue related to the August 2024 eruption at Reykjanes, SW Iceland

Here we present data on the spatiotemporal distribution of seismicity and CO2 flux from the highly active Svartsengi–Eldvörp volcanic system (hereafter referred to as Svartsengi) on the Reykjanes Peninsula. Data were collected between July and September 2024. The area is marked by repeated fissure eruptions associated with rapid magma propagation since November 2023. The eruptions are part of an ongoing volcanic sequence with intermittent pauses. The seismic and gas flux datasets support the idea, that multidisciplinary approaches are important for the identification of potential eruption sites and an improved hazard assessment in volcanic areas.
