What is the function of the Strong Motion System? A. Interfaces with the Response Spectrum Recorders providing the analog indication of recorded data.B. Gives local visual indication of seismic activity at the Containment base slab (2000' Auxiliary building).C. Provides engineering with a permanent recording on magnetic tape of local peak acceleration.D. Digitally records the acceleration of the earth at selected locations due to earthquakes.
