a Overhead view of the final earthquake locations during the 2017−2019 unrest at Öræfajökull along with the seismic (tan) and geodetic (InSAR and GNSS; blue) inversion sources. (b, c) are north-south and east-west representations of the modeled sources along with the earthquake location. d 3-dimentional rendering of the earthquake and modeled sources beneath Öræfajökull. The LET source is formed from the inversion area where Vp/Vs ratios are greater than 1.84. Earthquake source color and size are controlled by the magnitude of the earthquake. Note, earthquake locations that appear to be inside or covering the inversion source/high Vp/Vs locations occurred before and/or after the full injection of melt (Fig. S2).
