Abstract : Field data were collected in the second part of a two-part study to establish seismic response characteristics, their distribution, and the environmental factors that control them in two seismic sensor test areas (Gamboa and Alpha), which are located at the U.S. Army Tropic Test Center (TTC) in the Panama Canal Zone. The data were gathered during the 1971 wet season. Detailed seismic and environmental data are presented, and special seismic response tests (drop-hammer, man-walking, vegetation-effects, repeatability, and ambient-noise) conducted in various environmental conditions at 24 sites in the Gamboa test area and 11 sites in the Alpha test area are described. In addition to seismic response and terrain factor complex maps prepared from the measured data, the empirical regression equations resulting from a multicorrelation analysis are shown to relate the seismic response descriptors (peak particle velocity, peak summed particle velocity, and frequency) to the environmental parameters. Color illustrations reproduced in black and white.
