Previously, SURFER had reported about the potential of an earthquake, and resulting tsunami, striking the West Coast. That was from a different fault line off the coast of Canada, the Cascadia Subduction Zone, which experts believe could shift in the future.

This tsunami warning is not related to that region.

For the current tsunami warning, stay tuned for more updates.
