DIRECT OPERATIONAL PROCEDURE: Select Sweep Sensor to scan sector voids for thermal heat or acoustic vibrations. Click cells on the 12x12 grid to sweep or deploy Shoring Beams to stabilize structural stress before attempting Excavation & Rescue.
Subsurface Radar Scan Cross-Section (12x12 Grid)
Active Tool: SCANNER SWEEP
Collapses post 7.4-magnitude events generate unstable tension arches. Placing shoring beams transfers dead load weight ($L_d$) away from void spaces, raising Structural Stability Index ($S_i$) above the collapse threshold.
Acoustic Signal Wavelet Attenuation
Subsurface vibration signals attenuate with depth ($d$) according to $A(d) = A_0 e^{-\alpha d}$. Multi-band acoustic filtering isolates survivor tapping pulses from ambient background seismic reverberations.
Thermal Infrared Mapping
Trapped human or animal bodies emit localized thermal gradients (+0.5°C to +2.5°C ΔT). High concrete thickness attenuates heat flux, requiring high sensor sensitivity calibration.
