Two tall refinery structures and an eight-story University women's dormitory structure were instrumented for measurement of response to ground motion generated by the Salmon event. The refinery is about l8 kilometers from Surface Zero;the dormitory is about 30.8 kilometers. NGS 19L velocity meters were deployed at several levels on the refinery structures, and Sprengnether portable displacement meters were used on the top and bottom floors of the dormitory.nMeasured peak top level velocities in the two refinery structures were 7-31 centimeters per second in the taller TCC structure and 5-6 centimeters per second in the DIB tower, at periods of 0.19 seconds and 0.20 seconds respectively. Peak top floor displacement in the dormitory was 0.15 centimeters with a period of about 0.43 seconds.nBlume observers reported a clearly perceptible motion in the dormitory, felt by uninformed persons on bottom and top floors. No official observers were present at the refinery but personnel working there also reported clearly perceptible motion.
