According to the most recent information from the Meteorological Office of Iceland, shifting winds could blow gas plumes from the eruption north and northwest of the eruption site, towards the towns of Vogar, Reykjanesbær, and Garður.
Winds from the South and Southeast are expected today, ranging from 5 to 10m/s. The model below shows a possible distribution for the gas today around 13:00.
However, the Meteorological Office warns that SO2 levels in the model may not be entirely up to date. For the most current air quality levels, residents and tourists are encouraged to refer to the Environmental Agency of Iceland’s website.
The gas plume currently poses no significant hazard, and the capital area will not be affected.
Nevertheless, visitors to the eruption site are urged to exercise caution. The Meteorological Office states that gas levels near the eruption site can exceed safe levels, especially in low wind conditions when gas can accumulate in the valley. In such conditions, it is recommended to stay high on the slopes. When visiting the eruption, it is best to position oneself upwind of the eruption to avoid potentially dangerous exposure.
Following the eruption, the magma has seen a relief of pressure, meaning a potential decrease in flow. Seismic activity has likewise decreased, with far fewer earthquakes detected than preceding the eruption.
