The 5.5-magnitude earthquake that rattled northern Vancouver Island over the B.C. Day long weekend was a sobering reminder that people living on Canada’s West Coast should prepare themselves for a major quake.

Two-thirds of Canadians recently polled in a Red Cross survey said they haven’t taken any steps to prepare for a disaster, like an earthquake, flood or tsunami, primarily because they don’t think it’s going to happen – or they simply haven’t thought about it.

The Red Cross says the survey results are particularly concerning for people living in B.C., where the coastline, especially Vancouver Island’s, is a hotbed of seismic activity. Situated where two ocean plates meet, seismologists say the region is overdue for “The Big One,” a catastrophic quake that would damage buildings, major infrastructure, and potentially result in the loss of life.

The Red Cross recommends families have an emergency kit that allows for 72 hours of self-sufficiency, in case it takes several days for first responders to reach your home in a disaster.

The agency just rolled out a new disaster preparedness calculator application developed by Majestic Media that tests how ready you are for an emergency.

The Facebook app lets users drag and drop the items they already have at home into a theoretical emergency kit. It then calculates how ready you are according to how many adults, children and pets are in your home.

The calculator will then generate a shopping list of items you need to build your own home kit, things like flashlights, batteries, water bottles, candles and waterproof matches. The list can also be downloaded to make shopping easier.

The tool will also be made available as a mobile app in coming weeks.

During an earthquake, those inside are advised to drop under any heavy furniture and cover your head to prevent being hit by any falling objects. If you can’t get under something strong, flatten yourself or crouch against an interior wall.

Public Safety Canada says to avoid the following during an earthquake: doorways, windows and tall furniture, elevators and downed power lines. It also advises to stay away from coastlines, in case the earthquake triggers a large ocean wave or tsunami.

There are 5,000 earthquakes each year in Canada, though most are minor.
