At the invitation of researcher Liu Jing from the State Key Laboratory of Earthquake dynamics, ProfessorYann Klinger from the Institut de Physique du Globe de Paris (IPGP) gave a lecture titled “What earthquake surface rupture do teach us about earthquake processes” in room 301 on September 24, 2019.

Professor Yann Klinger is a senior researcher in the field of active tectonics at the IPGP and is currently a contributing professor at the University of San Diego. He has been engaged in research on active tectonics and paleoearthquakes, and most of his research areas are in Asia and the Near East. He has paid special attention to fault geometry and the interaction between fault geometry and earthquake rupture propagation, and he is very good at carrying out detailed mapping of fault geometry and tectonic landforms based on field research and remote sensing images. He has done a lot of research on large faults such as the San Andreas Fault, the Dead Sea Fault, the Fuyun Fault, and the Haiyuan Fault. His research results have been published in world-renowned journals such as Nature Geoscience, Geology, Geophysical Research Letters, and the Journal of Geophysical Research, and he has published 88 articles with a total of 3,780 citations.

In his academic report, Professor Yann Klinger introduced a method of identifying surface ruptures, co-earthquake displacement distributions, fracture branches, and fracture patterns using high-resolution image data based on some typical seismic surface rupture research examples, and discussed the possible causes of geometric complexity of surface ruptures. He presented a new idea of using large amounts of displacement measurement data to reveal different earthquake periods and carry out paleoearthquake research. Based on the matching of optical remote sensing image data from before and after an earthquake, he proposed a method to determine the distribution of co-earthquake displacement, and exploredthe interaction between fracture geometry and earthquake fracture propagation mode by establishing a fracture dynamics model based on the surface rupture distribution. He also introduced a method of identifying fault and fracture segments using the model. This report was broad in thought and rich in content, and fully discussed the importance of earthquake surface ruptures in the study of active faults.

This report attracted more than 60 scientific personnel to participate. The response was warm, and the atmosphere was active. Scientific personnel in attendance carried out in-depth discussions on studies related to surface rupture, which promoted mutual enlightenment and benefit.
