Time-dependent deformation and fracture evolution around underground excavations
Geomatics, Natural Hazards & Risk, 2020 A numerical time-dependent deformation model of rock by incorporating the stress corrosion model into a three-dimensional discrete element code was established to investigate time-dependent deformation and fracture evolution of surrounding rock around ...

Regional variations in the diffusion of triggered seismicity [PDF]
, 2005 We determine the spatiotemporal characteristics of interearthquake triggering in the International Seismological Centre catalogue on regional and global scales. We pose a null hypothesis of spatially clustered, temporally random seismicity, and determine

Seismicity from february 2006 to september 2007 at the Rwenzori Mountains, East African Rift: earthquake distribution, magnitudes and source mechanisms [PDF]
, 2012 We have analysed the microseismic activity within the Rwenzori Mountains area in the western branch of the East African Rift. Seismogram recordings from a temporary array of up to 27 stations reveal approximately 800 events per month with local ...

Seismicity and seismic hazards
, 2001 Many earthquakes occur along Canada's western margin near the edge of the North American Plate, but others occur within the plate in Arctic and southeastern Canada. Damaging earthquakes have occurred throughout history in both Eastern and Western Canada, and will undoubtedly recur in the future.

Heterogeneous Fracture Slip and Aseismic‐Seismic Transition in a Triaxial Injection Test
Geophysical Research Letters, 2020 Fault/fracture slip and seismicity caused by fluid injection are of major interest to subsurface science and engineering. However, some fundamental aspects of the temporal and spatial evolutions of induced seismicity remain unresolved.
