Abstract: A geological subsurface movement detection system that is configured to provide detection of movement in a subsurface area so as to provide data regarding issues such as but not limited to sinkhole development. The present invention includes an implant sensor assembly that is placed within a casing that has been installed in a bored hole in the ground. The implant sensor assembly includes a switch housing that is operably coupled to a contact member wherein the contact member is operably coupled utilizing a spring member. The switch housing includes a first switch and a second switch disposed in the interior volume that are electrically coupled on a circuit. A signal generator is operably coupled to the implant sensor assembly via a wire and is operable to send a pulse electrical signal thereon. A computing device is operably coupled to the signal generator and is operable to collect signal profile data.
