B.C. Unveils Groundbreaking Earthquake Early Warning System
In a significant advancement for disaster preparedness, British Columbia has officially launched its Earthquake Early Warning (EEW) system. Announced on August 29, 2024, this state-of-the-art system aims to provide crucial seconds of warning before a significant earthquake strikes, potentially saving lives and reducing damage.
The new EEW system, now operational across B.C., leverages a sophisticated network of sensors to detect seismic activity. Specifically, it targets earthquakes with a magnitude of 5.0 or higher. Once an earthquake is detected, the system sends out alerts through various channels including cellphones, radios, and televisions. This gives residents a brief but potentially life-saving warning of "seconds to tens of seconds" before the shaking begins.
As Natural Resources Canada highlights, these vital seconds allow people to "Drop, Cover, and Hold On," a critical protective measure during seismic events. B.C. Minister of Emergency Management and Climate Readiness, Bowinn Ma, emphasized the importance of these seconds, noting that they could be the difference between life and death in a major quake.

Jonathan Wilkinson, the Minister of Energy and Natural Resources, underscored the broader context of the EEW system. He pointed out that while Canada experiences nearly 5,000 earthquakes annually, most are minor and pose little threat. However, significant earthquakes are inevitable, making early warning systems crucial. The federal government's $36-million investment in earthquake warning systems reflects a commitment to safeguarding vulnerable regions and protecting millions of Canadians.
The EEW system is designed not only to alert individuals but also to activate automatic safety measures for critical infrastructure. For example, it will halt trains to prevent derailments, stop aircraft from landing, and close traffic to bridges and tunnels. This comprehensive approach ensures that both people and infrastructure are better protected during an earthquake.
The launch of this system is part of a broader initiative by Ottawa, which began in 2019, aiming to expand such warning systems across Canada. Following the rollout in B.C., similar systems are expected to become operational in eastern Ontario and southern Quebec later this year.
Although the EEW system cannot predict earthquakes, it represents a significant upgrade from previous systems, which could only provide alerts after an earthquake had begun. The further people are from the epicenter, the more advance notice they will receive, making this a vital tool for enhancing public safety.
In summary, British Columbia's new Earthquake Early Warning system marks a major step forward in earthquake preparedness. With its ability to provide early warnings and activate protective measures, it promises to enhance safety and resilience in the face of natural disasters.
