In order to strengthen disaster prevention control under deep resource development and space utilization, it is necessary construct a damage intrinsic model complex stress states predict the mechanical behavior of deep-rock mass cyclic loading. An indoor uniaxial loading test on sandstone was carried out in this paper. By analyzing properties energy transformation failure process, assumed that ...

Subsurface interaction between critically stressed seismogenic faults and anthropogenic fluid injection activities has caused several earthquakes of concern over the last decade. Proactive detection reverse strike-slip inherent in Alberta Basin is difficult, while identification likely to become even more challenging. We present a conceptual framework evaluate potential undetected faults, withi...

Crustal inflation near the Three Sisters volcanic center documented since mid-1990s has persisted for more than two decades. We update past analyses of event through 2020 by simultaneously inverting InSAR interferograms, GPS time series, and leveling data time-dependent deformation source parameters. explore several models to estimate how rate varied identify parameters that can reproduce measu...
