Abstract

Se presentan tecnicas para determinar la desviacion de un reloj adaptado para colocarlo bajo la superficie. Se transmiten senales sismicas a traves del medio subterraneo desde una ubicacion exterior en tiempos seleccionados, se reciben senales acusticas asociadas con las senales sismicas transmitidas con sensores acusticos en ubicaciones interiores identificadas. Se determina el primer y el segundo tiempo de transito para las senales acusticas recibidas en una ubicacion interior de referencia identificada usando el reloj. Para determinar la desviacion del reloj, se calcula la diferencia de tiempo entre el primer y el segundo tiempo de transito de la senal en el punto de referencia.
