Large earthquakes can cause devastating ground shaking and tsunamis, but understanding their rupture behavior in real time remains a major scientific challenge. This project aims to improve imaging and interpretation of the rupture processes of large earthquakes around the world. By improving an analysis method that uses waves recorded by seismic array called "back-projection," it is possible to visualize an earthquake rupture in time and space. The outcome of this research will produce more accurate measurements of how fast and how far earthquake ruptures travel. The results will help scientists identify unusual behaviors of large earthquakes like so called ‘super-shear ruptures’, which radiate unusually intense shaking. The findings of this study may lead to better earthquake early warning and hazard mitigation strategies. This research also provides valuable training to graduate students and includes science outreach efforts to engage K–12 students and the broader public through hands-on activities and educational field trips. The outcomes will support public safety by advancing our fundamental knowledge of how earthquakes happen. This project aims to systematically investigate the rupture characteristics of global large earthquakes (M ≥ 7.0) from 2000 to 2022 using advanced seismic back-projection (BP) techniques. Applying the Slowness-Enhanced Back-Projection method to correct spatial errors caused by 3D Earth structures will allow more accurate estimates of rupture
