New early earthquake warning system activated in B.C.

An earthquake early detection system has been activated in British Columbia to provide the public with a few seconds of warning 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.
The alerts will be sent “seconds to tens of seconds” before strong shaking beings, giving people a bit of time to “drop, cover and hold on,” according to a statement from Natural Resources Canada.
“We cannot stress this enough, during an earthquake, every second counts,” Wilkinson said at a news conference Thursday morning.
He said the system, jointly announced by the federal and B.C. government, will also allow critical infrastructure to take immediate action, such as halting traffic from driving onto bridges or into tunnels.
The system was first announced in early May on the B.C. government website.
We’ve all been told to prepare for “The Big One” — a massive earthquake that is forecast to bring destruction to the Lower Mainland. While the damage will be severe, not every part of the region will be hit the same way. Darius Mahdavi went out with some researchers who are creating detailed mapping that outlines the risk at a more granular level.
B.C. Minister of Emergency Management and Climate Readiness Bowinn Ma says seismologists have been warning for decades of a major earthquake in the province, and the new system will give “crucial seconds” of warning.
“These crucial seconds might not sound like a lot right now, but they will mean life and death for many people during an extreme earthquake,” 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.
“Earthquakes aren’t 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,” 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 Canada Research Chair at the School of Earth and Ocean Sciences at the University of Victoria, said B.C. 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 “shake like jelly” when a seismic wave hits, Nissen said, so having the early warning system in place is “a very exciting development.”
But Nissen said it’s 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.
“We need to retrofit older buildings, especially schools and hospitals, B.C. 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.”
The new system is part of the federal government’s $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.
