Abstract Landslides sometimes creep for decades before undergoing runaway acceleration and catastrophic failure. Observing and monitoring the evolution of strain in time and space is crucial to understand landslide processes, including the transition

Debris-flows present a natural hazard to the safe operation of linear infrastructure in mountainous environments. The most significant contributor to debris-flow occurrence is a supply of readily erodible material, often created by rockfalls and othe

This study presents a point cloud de-noising and calibration approach that takes advantage of point redundancy in both space and time (4D). The purpose is to detect displacements using terrestrial laser scanner data at the sub-mm scale or smaller, si

In Western Canada, geohazards can be related to tectonic events, such as earthquakes and volcanoes, but many are weather-driven events, such as floods, landslides, rockfalls, and snow avalanches. Anthropogenic activities, such as residential developm

Two fundamental fracturing mechanisms act as the primary drivers for burden removal in rock blasting: the propagation of radial cracks from the borehole due to the internal detonation pressure and the tensile failure relatively close to a free surfac
