More than 570,000 people practised their drop, cover and hold on skills at precisely 10:18 a.m. as part of this year's Great B.C. ShakeOut drill.
When the clock struck, participants dropped to the ground, took cover under a sturdy desk or table and held on for about 60 seconds to protect themselves in the event of a real earthquake.
Seismologists contend a major shaker occurs about every 300 years, and a big one in the region is overdue.
Millions more people participated in the drill today -- including in California, Nevada, Oregon and even Guam.
