SG Superconducting Gravimeter
Introduction
The superconducting gravimeter (SG) is an integrated gravity sensor that measures small gravity changes caused by mass redistribution in the surrounding environment. Although it records the total gravity change, individual contributions can be separated through analysis.
Applications
Current applications focus on global gravity effects such as Earth tides, seismic and nuclear modes, the nearly-diurnal free wobble, and polar motion. When studying a particular effect, the others are treated as noise and removed from the data.
Future Direction
Future work will focus on regional environmental change assessment, combined with GPS-derived crustal deformation, to interpret tectonic activity and contribute to earthquake hazard mitigation.
