Linking earthquake kinematics with dynamics
Session ID#: 80857
Session Description:
Earthquake rupture kinematic observations, fundamental rock physics and dynamic simulations have to converge to accurately quantify seismic hazards. Owing to the rapidly increasing quality and coverage of geophysical, geodetic and geological observations of earthquakes, as well as the explosively growing computational power, both kinematic and dynamic rupture processes have been resolved with unprecedented details. These progresses have been shedding new insights into reducing the gap between earthquake kinematics and dynamics. In this session we solicit contributions on all studies relevant to earthquake rupture kinematics and dynamics from seismology, geodesy, geology and lab experiments. Topics include but are not limited to, imaging of earthquakes ruptures, fault morphology mapping, fault zone structure imaging, earthquake cycle observations from paleoseismology and geodesy, dynamic rupture, earthquake cycle simulations, and rock experiments.
