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. Lidar-derived DEM data
