The saved simulation uses a straight hypocentral path and fixed wave speeds. An illustrative epicentral distance forty-five kilometers and depth eighteen point five kilometers give a path about forty-eight point six six kilometers by the square root of distance squared plus depth squared. Dividing by six kilometers per second gives the P arrival about eight point one one seconds; dividing by three point five gives the S arrival about thirteen point nine seconds. Both bars share forty pixels per second. These are saved demonstration assumptions, not operational earthquake alerts. This attenuation source exponentiates its written logarithmic acceleration formula, then multiplies by the selected soil factor. At illustrative magnitude six point three and the same forty-eight point six six kilometer path, hard bedrock factor one gives the first acceleration. Soft sediment factor two point two five gives exactly two point two five times that value before the source clamps its range. Both bars show percent of gravity on one scale. The formula is an authored approximation; the source labels do not independently validate a published ground-motion model or actual local conditions. The early warning lead in this source is the nonnegative difference between S and P travel times. For a thirty-kilometer path, dividing by three point five and six gives about three point five seven seconds of separation. Doubling path to sixty kilometers doubles the separation to seven point one four seconds. Both bars measure seconds on a common eighty-pixel scale. This difference omits sensor detection, network and processing latency. It must not be presented as an available real-world warning interval. The complete exports retain all original parameters and calculated telemetry.
