Dr. Daniele Cheloni

Space Geodesy Applied to the Study of Active Tectonics and Earthquakes

My research is to use Earth Observation satellite data (GNSS and InSAR) to understand the deformation of the Earth’ crust, and integrating these measurements with seismology and field studies of active faulting. I have extensive experience of working in actively deforming areas (e.g. Apennines and Alps in Italy; East and North Anatolian Fault in Turkey; Greece; Japan) and have investigated Earth deformation ranging in scale from individual earthquakes (e.g. 2009 L’Aquila; 2012 Emilia; 2016-2017 Central Italy; Lefkada 2017; 2020 Elazig; 2020 Samos) through to the accumulation and release of strain in the whole seismic cycle (e.g. interseismic and post-seismic deformation; aseismic phenomena) and to the integration of geodetic data in seismic hazard practices (e.g. relation between strain rates and seismicity rates). My main research interests therefore concern lithosphere deformation mainly associated with seismic cycle, and a large part of my work consists in elastic modeling.
