Kinematic Inversion of Physically Plausible Earthquake Source Models Obtained from Dynamic Rupture Simulations
One approach to investigate earthquake source processes is to produce kinematic source models from inversion of seismic records and geodetic data. The setup of the inversion requires a variety of assumptions and constraints to restrict the range of possible models. Here, we evaluate to what extent physically plausible earthquake scenarios are reliably restituted in spite of these restrictions. ...
متن کاملVariability of Near-Field Ground Motion from Dynamic Earthquake Rupture Simulations
This study investigates near-field ground motion variability due to dynamic rupture models with heterogeneity in the initial shear stress. Ground velocity seismograms are synthesized by convolving the time histories of slip velocity obtained from spontaneous dynamic rupture models with Green’s functions of the medium calculated with a discrete wavenumber / finite element method. Peak ground vel...
متن کاملSource rupture process of the 2016 central Tottori, Japan, earthquake (MJMA 6.6) inferred from strong motion waveforms
The source rupture process of the 2016 central Tottori, Japan, earthquake (MJMA 6.6) was estimated from strong motion waveforms using a multiple-time-window kinematic waveform inversion. A large slip region with a maximum slip of 0.6 m extends from the hypocenter to the shallower part, caused by the first rupture propagating upward 0–3 s after rupture initiation. The contribution of this large ...
متن کاملEarthquake source characteristics from dynamic rupture with constrained stochastic fault stress
[1] One of the challenging tasks in predicting near-source ground motion for future earthquakes is to anticipate the spatiotemporal evolution of the rupture process. The final size of an event but also its temporal properties (propagation velocity, slip velocity) depend on the distribution of shear stress on the fault plane. Though these incipient stresses are not known for future earthquakes, ...
