A seismologist with Natural Resources Canada says experts will look into a 4.4 magnitude earthquake that struck northeastern B.C. Monday to determine if it was natural or linked to hydraulic ...

A new kind of earthquake has been detected in western Canada, one that shakes the ground slower and longer than typical seismic events. These earthquakes, recorded during hydraulic fracturing for oil ...

Over the last decade, seismologists have demonstrated a troubling corollary of the extraordinary shale boom: the disposal of liquid waste from fracking operations and other fossil fuel production has ...

Wastewater injection resulting from oil and gas production in Oklahoma caused a dramatic rise in seismic activity in the state between 2009 and 2015. But regulatory efforts to backfill some injection ...

To date, our group has investigated multiple aspects on induced earthquakes and their impact on infrastructure. Aspects of this completed research include how much the seismic hazard has increased, ...

Global distribution of natural and induced seismicity. Natural earthquakes with moment magnitude higher than 5 are color-coded according to their hypocenter depth (upper right colorbar, U.S.

The Tiampo group uses InSAR (Interferometric Synthetic Aperture Radar) to study the surface deformation associated with induced seismicity. InSAR time-series analysis, achieved through a collection of ...
