Imaging the Rupture Processes of Earthquakes Using the Relative Back-Projection Method

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
