The concerned area includes the Alaskan peninsula, the Eastern Aleutian islands, and Kodiak Island. People were advised to stay from the water bodies and the beaches in the area.

The quake was recorded at a fairly shallow depth of 6km (3.8 miles), 55 miles southwest of the small city of Sand Point. The Alaskan Unit of the US National Weather Service (NWS) tweeted, “Significant inundation is feasible, or it is already taking place.”

Safety Precautions

The Alaskan branch of the NWS advised the people in the affected region to move to higher grounds in order to avoid possible danger.

The residents of Anchorage, the biggest city in the state, seemed to have received the warnings, too, as they were told to brace themselves for impact like the previously mentioned areas. However, the US National Weather Service stated that the area was not part of the affected regions.

Unrelated Volcanic Activity

While all these were taking place, the Alaska Volcano Observatory mentioned that an explosive eruption of the Aleutian volcano, Shishaldin, was going on.

They further said that the Aviation Colour Code was raised to red because of the magnitude of the ash cloud. However, the post clarified that the earthquake had nothing to do with the volcanic activity; they were not in any way related.
