Data processing means are described for calculating an estimated time of arrival of a seismic or microseismic P or S wave at a sensor station, based on a P to S wave velocity ratio, a calculated estimated time of origin of the event and, where the estimated arrival time of a P wave is to be calculated, a picked arrival time of the S wave at the sensor station or, where the estimated arrival time of a S wave is to be calculated, a picked arrival time of the P wave at the sensor station.

La présente invention concerne des systèmes de traitement de données pour calculer un moment d'arrivée estimé d'une onde sismique ou microsismique P ou S au niveau d'une station de détection, sur la base du rapport de vitesses d'onde P sur S, un moment d'origine estimé et calculé de l'événement et, lorsque le moment d'arrivée estimé d'une onde P doit être calculé, un moment d'arrivée choisi de l'onde S au niveau de la station de détection ou, lorsque le moment d'arrivée estimé d'une onde S doit être calculé, un moment d'arrivée choisi de l'onde P au niveau de la station de détection.
