3D model improves earthquake hazard assessment accuracy

An international study has created a more accurate 3D model to simulate earthquake rupture, improving hazard assessments. This advancement aims to better predict ground shaking and potential damage. The study, using data from the 2023 Turkey earthquake doublet, offers a detailed understanding of strong shaking patterns. The model accounts for complex fault geometry and Earth structure, crucial for predicting intense seismic waves. The research highlights the impact of rupture speed changes, including supershear ruptures, on ground shaking. This is particularly relevant for seismically active regions, potentially aiding in infrastructure planning and resource allocation.
