The American Geophysical Union (AGU) Annual Meeting was a blast. With over 25,000 attendees from 100+ countries, this has been the largest Earth and space science conference I have ever been to. As part of an oral session about Recent Earthquakes Across the Globe: Analysis of Main Shocks, Aftershocks, and Secondary Hazards for Preparation, Rapid Response, and Recovery, I presented our recently published study on the multi-event and multi-segment rupture propagation of the 2024 moment magnitude 7.5 Noto Peninsula, Japan, earthquake and how it governs tsunami generation. Using a multiple Centroid Moment Tensor (CMT) Bayesian inversion for tsunami modeling is a new approach and sparked interest of the scientific community. Other exciting presentations that shed light on this earthquake include landscape changes, closed-circuit television (CCTV) footage analysis for tsunami detection, hypotheses about the rupture onset with dual-initiation in connection with a strong fault asperity versus re-nucleation due to preceding fluid migration and fault valving behavior, urgent marine seismic observation in the source region using ocean bottom seismometers (OBSs) to obtain precise aftershocks, and many others.
This concludes this blog post for now. No liability is taken for the accuracy, completeness or timeliness.
