| Summary: | This repository is providing the InSAR data generated from the Copernicus Sentinel-1A and 1B satellites and as published in the paper Flóvenz et al. (2022) Cyclic unrest in a geothermal field as a harbinger of the Fagradalsfjall eruption, Iceland. Nature Geosciences, NGS-2021-06-01178 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±0.05 km3 and a density of 850±350 kg/m3. The geodetic data relevant for the publication and provided here include: 1. Displacement from ascending geometry 2. Displacement from descending geometry 3. Vertical displacement component 4. Horizontal displacement component These data are available for the following bands and dates: band date 58 07-01-2020 57 13-01-2020 56 19-01-2020 55 25-01-2020 54 31-01-2020 53 06-02-2020 52 12-02-2020 51 18-02-2020 50 24-02-2020 49 01-03-2020 48 07-03-2020 47 13-03-2020 46 19-03-2020 45 25-03-2020 44 31-03-2020 43 06-04-2020 42 12-04-2020 41 18-04-2020 40 24-04-2020 39 30-04-2020 38 06-05-2020 37 12-05-2020 36 18-05-2020 35 24-05-2020 34 30-05-2020 33 05-06-2020 32 11-06-2020 31 17-06-2020 30 23-06-2020 29 29-06-2020 28 05-07-2020 27 11-07-2020 26 17-07-2020 25 23-07-2020 24 29-07-2020 23 04-08-2020 22 10-08-2020 21 16-08-2020 20 22-08-2020 19 28-08-2020 18 03-09-2020 17 09-09-2020 16 15-09-2020 15 21-09-2020 14 27-09-2020 13 03-10-2020 12 09-10-2020 11 15-10-2020 10 21-10-2020 9 27-10-2020 8 02-11-2020 7 08-11-2020 6 14-11-2020 5 20-11-2020 4 26-11-2020 3 02-12-2020 2 08-12-2020 1 14-12-2020 |
