CNN- An earthquake with a preliminary magnitude of 7.8 struck off the coast of Alaska early Wednesday morning.
“Anything below 70 kilometers is considered a shallow quake,” CNN meteorologist Allison Chinchar previously said. “That’s important, because shallow earthquakes often cause the most damage, compared to the ones that are deeper, regardless of the strength.”
But all tsunami warnings and advisories were canceled early Wednesday morning, according to the National Weather Service.
