Shortly after 10:15 a.m. Thursday, more than 930,000 British Columbians will “drop, cover and hold on” as part of a province-wide practice test for when a real earthquake strikes.
The annual Great British Columbian ShakeOut drill is part of a worldwide disaster preparedness test.
There are roughly 3,000 tremors and quakes across the province each year. According to earthquake analysts, the Cascadia subduction zone – a fault running from northern Vancouver Island to California – is the area of greatest risk in B.C. for tremors. Scientists have been keeping a close eye on the Juan de Fuca plate, which is skidding below the North American plate and has the potential to slip and cause a powerful quake.
Nearly 1 million participants registered! 🤩

The last major earthquake, which registered as 7.8, was in 2012 in Haida Gwaii. Since then, many researchers have shared their theories on when “the big one” will hit.
“Earthquakes don’t make appointments. We have to be ready when they arrive,” Naomi Yamamoto, president of the BC Earthquake Alliance said in a statement to Black Press Media.
“Practising ‘Drop, Cover and Hold On’ builds muscle memory and is a great way to be prepared to survive and recover quickly.”
In the case of an earthquake, you should:
- Drop where you are onto your hands and knees.
- Cover your head and neck with one arm and hand. If possible, crawl underneath a nearby desk or chair for shelter.
- Hold on until the shaking stops. Wait for the shaking to stop and count to 60 before emerging from your safe area to allow objects that may have shifted during the shaking to settle.
This year’s drill comes just a few days after scientists in the U.S. announced their discovery of “stormquakes,” the combination of two disasters: hurricanes and earthquakes.
The shaking of the sea floor during hurricanes and nor’easters can rumble like a magnitude 3.5 earthquake and can last for days, according to a study in this week’s journal Geophysical Research Letters.
While they are fairly common, stormquakes weren’t considered much more than seismic background noise by researchers until now.
Wenyuan Fan, a Florida State University seismologist who was the study’s lead author, told the Associated Press that her team discovered 14,077 stormquakes between September 2006 and February 2015 in B.C., as well as the Gulf of Mexico and off Florida, New England, Nova Scotia, Newfoundland and Labrador.
In an emailed statement, Public Safety Minister Mike Farnworth encouraged all British Columbians to participate in the drill, which starts at 10:17 a.m. PST.
“If you live in an active earthquake zone, knowing what to do when the shaking starts could save your life.”
