Minimum 1D Velocity Model from Local Earthquake Data in the Provence Region, South-Eastern France
Tóm tắt
We computed a one-dimensional (1D) velocity model and station corrections refering to the Provence region (South-eastern France) by inverting P-wave arrival times recorded on an eight-station local seismic network. Using this velocity model and the program HYPOELLIPSE (Lahr, 1989), we relocated a set of 108 local events. The quality comparison between previous earthquake locations and new relocated shows a good improvement. The obtained “Minimum 1D velocity model” can be used in a better-quality routine for earthquake location and represent a first step towards more detailed seismic studies in the Provence region.
