Data for GRL paper "On the move: 2023 observations on real time graben formation, Grindavík, Iceland"

This repository contains following data: 1. Seismicity data • file: Grindavik_Relocations.txt Earthquake relative locations 2. InSAR data • file: Grindavik_nearU_m.tif Near-Up vertical displacements during 10-11 November 2023 derived from pixel offset tracking of SAR imagery from ICEYE, COSMO-SkyMed and Sentinel-1 satellites used in Fig. 2. The values are in meters and relative (the 0 is arbitrary). The coordinate system is WGS84 (geographic, EPSG:4326), the resolution is about 30 m East and 20 m North. 3.
