New earthquake alert system promises crucial seconds for safety in Canada

• British Columbia launches Earthquake Early Warning system to provide crucial seconds of warning before strong shaking starts.
• The EEW system enhances preparedness so the public can take immediate protective actions - reducing casualties and property damage.
• The system issues alerts via the National Public Alerting System seconds before shaking begins.
• Available now in BC, and operational in eastern Ontario, southern Quebec, and beyond later this year.

Driving the news: Officials in British Columbia have launched the Earthquake Early Warning (EEW) system, aiming to provide crucial seconds of warning before strong shaking starts. The system is designed to reduce injuries, deaths, and property damage.

How it works: The EEW system uses a network of sensors to detect earthquakes and issue alerts via the National Public Alerting System seconds before shaking begins.

• The system can also trigger automatic protective measures for critical infrastructure, such as halting traffic on bridges and stopping trains.
• "By providing crucial seconds to seek safety, we can save lives, reduce injuries and minimize damage to infrastructure and the environment. This system is a vital tool for emergency responders, healthcare providers and all Canadians," said The Honourable Harjit Sajjan, Minister of Emergency Preparedness.

Operational proof: Shortly after its launch, the EEW system detected a 4.2 magnitude earthquake off Haida Gwaii's west coast. Although below the public alert threshold, it successfully issued a technical alert to officials, demonstrating its capability.

Why it matters: The EEW system enhances earthquake preparedness by allowing people to take immediate protective actions. It builds on Natural Resources Canada's expertise in earthquake information.

• Collaboration with critical infrastructure operators ensures they receive detailed earthquake alerts.
• "Timely warnings can be the difference between life and death in the face of earthquakes. This early warning system is a critical investment in Canada's emergency preparedness and response, empowering individuals and communities to take action and reduce the devastating impact of seismic events," Sajjan added.

Broader impact: The EEW system is expected to significantly improve earthquake preparedness in Canada, particularly in high-risk regions. By providing timely warnings, it addresses a critical need for enhanced emergency response.

• The system will issue alerts for earthquakes with magnitudes greater than 5 and intensity levels higher than IV.
• About one such earthquake occurs annually in Canada, with around 5,000 detected each year.

Availability: The full system will be operational in eastern Ontario and southern Quebec later this year, covering over 10 million people. Future updates may expand coverage and capabilities nationwide.

• The government plans to continue working with provinces, territories, and Indigenous partners to strengthen other forms of disaster mitigation, preparedness, and response efforts.
