A dedicated seismic array for nuclear test ban monitoring at regional distances

Abstract

In view of a possible nuclear test ban in the Nevada Test Site of thc USA some tcchnical aspects of seismic arrays are considered, in order to solve the problem of monitoring from Mexican territory. Dedicated arrays applied here to a particular case in Mexico, are proposed as a means for achieving adequate monitoring capabilities at regional distances with a minimum of means. The region around Tecate in Northern Baja California is proposed as the preferred site. Preliminary possible array designs are presented to illustrate the proposed methodology based on the use of minimal on-line operations and an azimuthal rejection switch.
