Cyclic unrest in a geothermal field as a harbinger of the Fagradalsfjall eruption, Iceland - INSAR data repository

<p>This repository is providing the InSAR data generated from the Copernicus Sentinel-1A and 1B satellites and as published in the paper</p> <p>Fl&oacute;venz et al. (2022) Cyclic unrest in a geothermal field as a harbinger of the Fagradalsfjall eruption, Iceland. Nature Geosciences, NGS-2021-06-01178</p> <p>We analyse deformation and seismicity for one year prior to the March 2021 Fagradalsfjall eruption in Iceland. We generate a high-resolution catalogue of 39,500 earthquakes using optical cable recordings and develop a poroelastic model to describe three pre-eruptional uplift and subsidence cycles at the Svartsengi geothermal field, 8 km west of the eruption site. We find the observed deformation is best explained by cyclic intrusions into a permeable aquifer by a fluid injected at 4 km depth below the geothermal field, with a total volume of 0.11&plusmn;0.05 km3 and a density of 850&plusmn;350 kg/m3.</p> <p>The geodetic data relevant for the publication and provided here include:</p> <p>1. Displacement from ascending geometry</p> <p>2. Displacement from descending geometry</p> <p>3. Vertical displacement component</p> <p>4.
