Tsunami and the big one: British Columbia
theweathernetwork.com
Wednesday, June 29, 2016, 2:48 PM - B.C.'s Lower Mainland is still waiting for the Big One -- a powerful earthquake in an area already prone to frequent earthquakes.
The region is part of the Cascadia Subduction Zone, where one tectonic plate is being subsumed beneath another. But the pressure has been building between the North American and Juan de Fuca plates, and scientists say there's a one-in-ten chance of a major quake in the next 50 years, powerful enough to rival Japan's Tohoku earthquake of 2011.
That was a Magnitude 9.0, and British Columbia and the U.S. Pacific Northwest experienced one of similar strength in the early 1700s.
But less talked about, but still dangerous, is the tsunami threat from such a quake, if it were to strike in the coming years.
Krissy Vann reports on that possibility in the video above.
