Alaska – M 5.8 – Strong earthquake near unpopulated Amatignak Island in Alaska

Earthquake Report comment :
A strong earthquake struck in the early morning (local time) of the Andreanof volcanic island archipelago in the Bering Sea. Within a radius of 200 km of the epicenter we have no record of people living here permanently.
The same area has been hit by many similar earthquakes in the recent days and weeks.
The magnitude is such that a tsunami IS NOT EXPECTED. However, in coastal areas of intense shaking, locally generated tsunamis can be triggered by underwater landslides.
The maximum slope in the area of the earthquake is 53% and the maximum altitude is 1565 m.

USA – Alaska – M 6.1 – Strong earthquake in an unpopulated area in the Bering Sea near Tanaga Island

Earthquake Report comment :
Based on reports from GDACS and USGS NO people are living in a radius of 200 km around the epicenter.
No widespread Tsunami will be triggered, although local Tsunamis generated by underwater landslides are always possible.
The nearast island to the epicenter is Ogliuga Island, it has an abandoned airfield located on Ogliuga Island, Aleutian Islands, Alaska.
About 30 km from the epicenter on Gareloi Island,  a stratovolcano. The island is uninhabited. Coastal cliffs provide nesting habitat for more than 600,000 seabirds, mostly for crevice nesting auklets.
The island also has two small glaciers. (Source : wikipedia)
