Earthquake Energy Radiation Across Spectrum: a multidisciplinary study

Objective

Destructions left after an earthquake are mostly caused by high-frequency ground motion that originates from the seismic source. I will exploit the natural continuity between geodetic and seismological data to illuminate high-frequency sources and their relations with changes in earthquake rupture speed. I propose an innovative Bayesian 2-step kinematic inversion in the frequency domain to investigate these destructive and poorly constrained high-frequency sources. This probabilistic approach is based on near-field data and a detailed analysis of the model parameter uncertainties, which allows better locating the HF sources. The project will bring new insights into how high-frequency relates to tectonic features, both in subduction zones and large continental faults. ERASMUS will be a collaborative effort between different earthquake-related communities to generate knowledge that can be included in more reliable seismic hazard assessment, impacting society significantly.
