Alaskan Margin

The Alaskan Margin refers to the edge of the North American tectonic plate along the southern coast of Alaska. It is a geologically active boundary where the Pacific Plate is slowly sliding beneath the North American Plate, causing earthquakes, volcanic activity, and specific landforms. This region is part of the Pacific Ring of Fire, known for its seismic activity. The margin's dynamic processes shape Alaska's rugged mountains, deep offshore trenches, and volcanic chains, playing a key role in the area's geology and natural hazards.
