VELOCITY MODEL [1 record]

Record 1 2006-01-25

English

Subject field(s)
  • Seismic Prospecting
  • Geological Research and Exploration
CONT

In this study, new seismic velocity information is employed to develop a 3-dimensional density model of the basin. Comparison of the calculated gravity response of this model with the observed gravity field validates the velocity model at large scales.

CONT

Traditionally, routine earthquake locations are obtained from linearized inversion using layered seismic velocity models.

French

Domaine(s)
  • Prospection sismique
  • Recherches et prospections géologiques
CONT

Dans cette étude, de nouvelles informations de vitesse sismique servent à développer un modèle 3-D de la densité du bassin. Une comparaison entre la réponse de la gravité calculée à partir de ce modèle et le champ de gravité observé valide le modèle de vitesse à de grandes échelles.

CONT

En sismique comme avec le radar géologique, la détermination de la vitesse de la première couche est primordiale pour la constitution d'un modèle de vitesse.
