“All earthquakes that occur less than 70 kilometers deep are considered shallow,” said CNN meteorologist Allison Chinchar. “This is important because shallow earthquakes often cause the most damage compared to deeper ones, regardless of magnitude.”

A tsunami warning was issued after the earthquake, according to the National Oceanic and Atmospheric Administration. The warning was in effect for southern Alaska and the Alaska Peninsula-Pacific Coast from Kennedy Entrance to Unimak Pass.
