RICHMOND, BRITISH COLUMBIA 鈥� For years, Metro Vancouver has been worrying about the threat of the 鈥淏ig One,鈥� a megathrust earthquake expected to hit coastal sa国际传媒 one day.
But before it finally hits, residents could get a precious warning.
An earthquake early detection system has been activated in British Columbia to provide the public and infrastructure managers with up to 鈥渢ens of seconds鈥� of notice ahead of a potentially harmful tremor.
Federal Energy and Natural Resources Minister Jonathan Wilkinson said when a strong earthquake is detected, alerts will be transmitted automatically to British Columbians via cellphones, radio and televisions.
He said the system, jointly announced by the federal and sa国际传媒 governments Thursday, would also allow managers of critical infrastructure to take immediate action such as halting traffic from driving onto bridges or into tunnels.
"Every year in sa国际传媒, nearly 5,000 earthquakes are recorded," Wilkinson said at a news conference in Richmond, sa国际传媒
"Fortunately, most of these are small and pose no serious threat, but large damaging earthquakes can and will occur," said Wilkinson, adding that the most potentially damaging tremors in sa国际传媒 could occur in western sa国际传媒, as well as the Ottawa-Qu茅bec City corridor.
sa国际传媒 Minister of Emergency Management and Climate Readiness Bowinn Ma said seismologists had been warning for decades of a major earthquake in the province, and the new system can give 鈥渟econds, to tens of seconds鈥� of advance warning for people to "drop, cover and hold on."
鈥淭hese crucial seconds might not sound like a lot right now, but they will mean life and death for many people during an extreme earthquake,鈥� said Ma.
She said British Columbians have witnessed emergencies over the past few years at a greater rate than ever, largely driven by climate change.
鈥淓arthquakes aren鈥檛 exactly a climate change hazard, but in addition to all of the other climate-driven hazards, it means that British Columbians need to be more prepared than before,鈥� said Ma.
She said the new earthquake warning system will allow every corner of the province to be "prepared and resilient."
Edwin Nissen, professor and sa国际传媒 Research Chair at the School of Earth and Ocean Sciences at the University of Victoria, said sa国际传媒 communities such as Tofino, Port Alberni and Victoria are at high risk if a large earthquake strikes because of their proximity to the West Coast.
Places in the southern suburbs of Metro Vancouver such as Delta and Surrey will also likely 鈥渟hake like a jelly鈥� when a seismic wave hits, Nissen said, so having the early warning system in place is "a very exciting development."
But Nissen said it鈥檚 also important to note that earthquake early warning systems are just part of emergency response, and people still need to get their toolkit ready.
He said the early warning won't stop buildings from being damaged, and therefore the province still needs stronger buildings.
鈥淲e need to retrofit older buildings, especially schools and hospitals, sa国际传媒 Parliament, the Crystal swimming pool here in Victoria," said Nissen. "There are lots of older buildings that are certainly vulnerable to the ground shaking, and the government will continue to have to retrofit those buildings.鈥�
The new system is part of the federal government鈥檚 $36 million plan to develop a warning system to protect regions vulnerable to earthquakes.
Wilkinson said the system will be expanded later this year to Southern Quebec and Eastern Ontario.
