 "finding": "The chamber barely touches the ground's own motion. Opening it in rock under a uniform horizontal stress and letting the rock settle, the lab's solver finds the surface above it sinks by 18.0 um per MPa (Eshelby's void with Okada's point sources: 25.5 um; a finer grid: 18.7 um). A passing Rayleigh wave strains the ground by hv V / c whatever its frequency, so the chamber's imprint on the line-of-sight velocity is 6.6e-05 of Giza's microseism motion: 3.2e-06 um/s. At the noisiest stations on Earth it would be 2.3e-04 um/s, at 1-3 Hz 3.4e-05 um/s, and under a truck 15 m away roughly 8.8e-01 um/s."
