A catastrophic earthquake hits Canada's West Coast. In Fault Lines CBC Vancouver Seismologist Johanna Wagstaffe guides you through two disastrous scenarios so you can prepare yourself, your family, and your neighbours.
Johanna sets up two different, equally likely scenarios. First, The Big One: a 9.1 mega-thrust earthquake. Then, the lesser known 7.0 magnitude crustal quake which is shallow and strikes beneath the city of Vancouver. The outcome is catastrophic.
