Project description
Improved characterisation of high-frequency sources enhances seismic hazard assessment
Seismic hazard assessment is critical to protecting lives and infrastructure. High-frequency ground motion is responsible for most of the destruction after an earthquake, often moving the ground under a building faster than the building can respond. The physical processes behind these high-frequency sources are poorly understood. With the support of the Marie Skłodowska-Curie Actions programme, the ERASMUS project will develop and apply an innovative Bayesian two-step kinematic inversion in the frequency domain to shed light on high-frequency sources and their relations with changes in earthquake rupture speed. The project will shed light on how high-frequency radiation sources relate to tectonic features leading to more reliable seismic hazard assessment and civil protection.
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.
