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.

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.
