Opportunities for postdocs in earthquake science and
tomography at University of Strasbourg. Feel free to
contact me if you are interested!
November 2017
Our paper on regional W-phase source inversions
in China has been accepted for publication in JGR. We show that W-phase solutions can be obtained within
4 to 7 min after the earthquake origin time (compared with 20 to 30 min at global scale) and extended to
smaller magnitude events (Mw>=5). See Publications.
