Seismic effects programs, Project Rio Blanco

These programs include: a seismic array to monitor the ground motion resulting from the detonation at distances varying from 3.7 miles to 93 miles from the emplacement well (EW); two seismic arrays to detect the aftershocks of the detonation and to locate the hypocenters of these aftershocks; a seismic array to study the correlation of structural damage to low-level ground motion; a seismic array to study structural response to the ground motion; a seismic array to monitor the ground spall caused by the detonation; an instrumental array to monitor changes in pore pressure resulting from the seismic wave; a structural bracing program to minimize the damage caused by the ground motion; and a pre- and postdetonation inspection of selected bridges in the area to detect any change due to ground motion.
