The principle of measuring unusual change of underground mass by optical astrometric instrument
Optical observations from a ground-based astrometric instrument provide a unique set of data sensitive to variations of local plumb line, which represent the change of local gravitational field on the ground. The local gravitational change could be caused by density variation or movement of undergro...
