SHORT HISTORY
The purpose of the network i, twofold: first, to prOvide , continuous monitor of the seismic activity on ,nd near the
plant site and thus determine location and magnitude of local earthquakes; second, to determine whether there i, , significant
difference in the ground motion of the two geologically different materials that occur at the surface of th, plant ,nd whether
the response varies over different thicknesses of coastal-plain sediments.
