The seismic simulator assigns constant P and S speeds by selected fault label. Its Romeral branch uses six point two and three point five kilometers per second. Both bars use one hundred pixels per kilometer per second. The Bucaramanga and Nazca selections use different assigned constants. These are written layer presets, not a three-dimensional ray-tracing solver or measured seismic arrival report. The soil selection assigns an amplification factor: two point eight for the source Bogotá branch, one point eight five for Medellín, and one point zero five otherwise. These bars compare the first and third assigned factors on one two-hundred-pixel scale. Acceleration is the written magnitude-distance proxy multiplied by that factor, then rounded to two decimals. The city names and coefficients are authored scenario labels rather than verified local hazard calibration. The written drift proxy uses rounded acceleration times eighteen point five, times a soil resonance multiplier and ten divided by damping percent. With an illustrative acceleration point five g in the branch with resonance one, damping five percent yields eighteen point five centimeters. Damping ten percent yields nine point two five centimeters. Both bars share thirty pixels per centimeter. This inverse damping demonstration is not a structural design calculation, failure prediction or safety assessment of a real building.
