We use the new global database of source time functions (STFs) and focal mechanisms proposed by Vallée (2013) using the automatic SCARDEC method (Vallée et al., 2011) to constrain earthquake rupture duration and variability. This database has the advantage of being very consistent since all the events with moment magnitudes Mw>5.8 that have...

We study the physical causes of the magnitude dependence of ground‐motion decay with distance that is observed on real data. Using stochastic simulations, we analyze the role played by anelastic attenuation Q (f), path duration, site effect (κ0), finite‐fault effect, and stress drop for a magnitude range between 4 and 7. We systematically look...

Although moderate-size earthquakes are poorly studied by lack of near-fault observations, they can provide key information about larger damaging earthquakes. Here we propose a new approach, inspired by double-difference relocation, that uses high-coherency waveforms recorded at neighboring sensors, to study the preparation phase and dynamics of...
