... deformations (vertical displacement, surface tilt and horizontal strain) as signatures in two different modalities: (i) isotropic volume change (Mogi model) and (ii) injection induced shear offset (Okada model) and compare the results with both the resolution of current geodetic tools and existing observations...

... CE material expected to be weakly orthorhombic. Reflectivity of the quartz crystal shows that the Schoch shift, observed in isotropic materials, is duplicated. This duplication of the Schoch shift depends on the azimuth and, can be used to identify principal planes of symmetry. Effects of tilting...

... extraction has been proven to be an effective method of subsidence damage control. The design of such layouts has to ensure that the tilt and strain values are acceptably small, first, over the alternating panel and pillar sequence and second, in the vicinity of the extremities of such a sequence when...

... the monitoring instrumentation and techniques as they relate to the mining and site conditions. The capability of a tiltmeter to detect and follow the tilt of the foundations caused by the mining subsidence sequence is demonstrated. Using data from this tiltmeter, the development of curvature in the foundations...
