Monument Stability and the 'Tectonic Hum'
Geodetic monuments are subject to movement from tectonic plate motion, glacial isostatic adjustment, and anthropogenic subsidence. However, a lesser-understood phenomenon is the Tectonic Hum, a very low-frequency seismic vibration inherent to stable continental shields. Surveys repeated too rapidly (e.g., within a 5-year window) often show s…
