Major fault line off the west coast could trigger a catastrophic magnitude 9 earthquake, research shows – and it’s due to a blow

by
The Cascadia Subduction Zone extends along a 600-mile stretch of the Pacific Ocean off the coasts of southern Canada, Washington, Oregon and northern California. If it erupts, it could cause a magnitude 9 earthquake to hit the region. The darker areas mark the region that would suffer the most damage and extend inland where the devastation would be more moderate

An underwater fault line along America’s west coast could trigger a megaquake that would be more devastating than California’s ‘Big One’, a new study suggests. Using underwater mapping techniques, scientists have mapped the Cascadia Subduction Zone – a 600-mile-long fault line stretching from southern Canada to Northern California – in unprecedented detail. It has been … Read more
