seismic activity escalated close to Mt. Þorbjörn and multiple magmatic
intrusions were detected. On the 24th of February 2021 the seismic activity
resumed with an earthquake of M5.7 next to Keilir and thousands of earthquakes followed
in the days and weeks after.Figure 1. Temporal

the eastern half of the craters was measured and found to be up to 40 m thick. Intense steam rises up from the craters, with occasional small ashy explosions. The noise of intense boiling and or degassing is heard from the craters. The crater rim is coated with fine ash that extends 20 m from the edge. Strong smell of sulfur around the craters.
At 20:45 the steam plume was measured to be at the altitude

3.2 Total Precipitation
As with surface air temperature (SAT), total precipitation (TP) depends on surface type and terrain
elevation (see Fig. 9). Similarly to SAT, the terrain of Iceland only induces a weak wave pattern
in the larger-scale northeast to southwest gradient in the GCM ensemble mean field of TP during
the 1961–90 control period, resulting in about 0.5 mm day 1 lower mean
