Fracture displacement monitoring in caves helps to identify potential dangers to human safety and has significant implications for their environmental protection. Such monitoring is also undertaken to study the preparatory factors that trigger breakdown or the kinematic behaviour of active tectonic faults and deep-seated gravitational slope deformations. Recently the authors designed and fabricated a novel positioning system for fracture displacement monitoring, and the system has been installed for testing in the British Cave Science Centre at Poole's Cavern, Buxton, Derbyshire. The positioning system records changes in an artificially generated electromagnetic field. Magnetic field data are immediately transformed into three-dimensional displacement data and the outputs are presented online in real time. Here, the first six months of monitoring results are presented. Two of the three displacement components, x and z, are characterized by conspicuous periods of pulsed instability in October 2019 and January 2020, whereas the third component, y, is characterized by a generally progressive displacement trend. Testing in the British Cave Science Centre has helped to demonstrate the feasibility of using the positioning system for fracture displacement monitoring in caves. Ongoing research focuses on reducing the physical size and energy requirements of the monitoring equipment so that it will be possible to deploy large sensor meshes in less accessible parts of the cave environment.
