Earthquake Early Warning
ONC’s Earthquake Early Warning System supports critical alerts before major shaking arrives.

ONC is developing a British Columbia solution for Earthquake Early Warning (EEW) capable of detecting earthquakes and issuing alerts before major shaking arrives at your location. ONC sensor data will be shared with government organisations to issue public alerts, and notifications can also be sent to operators of infrastructure.

EEW is a collaboration among government, academia, industry and communities, including ONC, Natural Resources Canada, Emergency Management BC, University of British Columbia, United States Geological Survey, and the Pacific Northwest Seismic Network.
