Beschreibung
This thesis adopts the relative back-projection method to dramatically reduce “swimming” artifacts by identifying the rupture fronts in the time window of a reference station; this led to a faster and more accurate image of the rupture processes of earthquakes. Mitigating the damage caused by earthquakes is one of the primary goals of seismology, and includes saving more people’s lives by devising seismological approaches to rapidly analyze an earthquake’s rupture process. The back-projection method described in this thesis can make that a reality.
Nominated as a prize-winning thesis by the department of Geophysics, School of Earth and Space Sciences, Peking University
Proposes a novel back-projection method for quickly and accurately imaging the rupture processes of earthquakes
Reveals the close connection between high-frequency energy releasing peaks and seismic damage to buildings near the causative fault
Presents the relative back-projection method as an effective and routine approach for studying the physics of earthquakes
