An educational program focusing on seismological activities for school and university students that trains in observational sciences and raises citizen awareness of natural hazards has been active in France since 1995. Over this quarter century, diff

During the 1982–1984 bradyseismic crises in the Campi Flegrei area (Italy), the University of Wisconsin deployed a network of seismological stations to record local earthquakes. In order to analyse the potential of the recorded data in terms of tom

At a local scale, travel-time tomography requires a simultaneous inversion of earthquake positions and velocity structure. We applied a joint iterative inversion scheme where medium parameters and hypocenter parameters were inverted simultaneously. A

Recording seismic events at teleseismic distances with broadband and high dynamic range instruments provides new high-quality data that allow us to interpret in more detail the complexity of seismic rupture as well as the heterogeneous structure of t

International audience; Velocity macromodel building is an essential step of the seismic imaging workflow. Indeed, obtaining acceptable results through migration or full waveform inversion is highly dependent on the kinematic accuracy of the backgrou

Summary A new formulation for first arrival traveltime tomography is introduced based on the traveltime and slopes of first arrival local coherent events for 2D TTI media. Here, we use Eikonal solvers in forward modeling to calculate slope and travel
