On the integrity of deformation monitoring [PDF]
Geomatics, Natural Hazards & Risk, 2020 In safety-critical applications, deformation monitoring systems are required to issue timely alerts when a deformation beyond a critical threshold occurs. Only a very small probability of failing to issue an alert when in fact one should have been given,
