Properties of Dynamic Earthquake Ruptures With Heterogeneous Stress Drop
Earthquake rupture is a notoriously complex process, at all observable scales. We introduce a simplified semi-dynamic crack model to investigate the connection between the statistical properties of stress and those of macroscopic source parameters such as rupture size, seismic moment, apparent stress drop and radiated energy. Rupture initiation is treated consistently with nucleation on a linea...
متن کاملEarthquake triggering by static and dynamic stress changes
[1] In this study we aim to understand the effect of static and dynamic stress changes in promoting earthquake failures on secondary faults. Toward this goal we solve the equation of motion of a spring-slider dynamic system including inertia and using rateand state-dependent constitutive laws. We separately investigate the dynamic response of this fault analog system to a sudden stress change r...
متن کاملDetection of Ruptures of Andaman Fault Segments in the 2004 Great Sumatra Earthquake with Coseismic Ionospheric Disturbances
Near field coseismic perturbations of ionospheric total electron content (TEC), caused by direct acoustic waves from focal regions, can be observed with Global Positioning System (GPS). They appear 10-15 minutes after the earthquake with typical periods of ~4-5 minutes, and propagate as fast as ~1 km/s toward directions allowed by ambient geomagnetic fields. Ionospheric disturbance, associated ...

15 صفحه اولA hypothesis for delayed dynamic earthquake triggering
[1] It’s uncertain whether more near-field earthquakes are triggered by static or dynamic stress changes. This ratio matters because static earthquake interactions are increasingly incorporated into probabilistic forecasts. Recent studies were unable to demonstrate all predictions from the static-stress-change hypothesis, particularly seismicity rate reductions. However, current dynamic stress ...
