Velocity model and station corrections used by N. Cuenot to locate seismic events recorded by the downhole and the surface network - Soultz-sous-Forêts 2000 Stimulation

Velocity model and station corrections described in the PhD thesis of <b>N. Cuenot</b>, used to calculate location of microseismic events of his first catalogue of the 2000 stimulation episode at Soultz-sous-Forêts.

N. Cuenot performed preliminary locations during his PhD using a modified version of the HYPOINVERSE program (Klein, 1978). An initial velocity model established by Darnet (2000) was first used but did not give satisfactory results. The velocity model was thus refined. P waves velocities were iteratively calculated by minimizing residual errors at the stations. The ratio Vp/Vs was similarly adjusted in the sedimentary layers. At least, station corrections were used to get hypocenters as precise as possible.


The first catalogue of events of the 2000 episode calculated by N. Cuenot using the HYPOINVERSE program is available ( https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS2000-catalogue ).
