Seismic Activity

These charts provide information relating to earthquakes in Alberta, and ground motion data from Alberta Geological Survey (AGS) seismic stations within the Regional Alberta Observatory for Earthquake Studies Network (RAVEN) monitoring network. These earthquakes include both natural and induced seismic events but exclude events relating to mining activities (blasts). 

Earthquake (E) is defined as thought to be naturally occurring.

Suspected Induced (SI) earthquake is defined as seismological events reported by industry following compliance with regulation or orders.

Known Induced (KI) earthquake is determined based on detailed seismologist analysis.

Please note that some lower magnitude seismic events could be influenced by the monitoring network and not entirely indicative of industry activity. For more detail, please visit the AER’s Earthquake Dashboard.
