Ring of Fire
Island-building
Forces Continue to Shape Alaska’s Aleutian Islands
The entire
chain of Aleutian Islands in the Alaska Maritime Refuge rides the northern arc
of the "Ring of Fire" – a line of inner friction where Pacific
plate of the earth’s crust grinds slowly under the continental plates surrounding
it.
This movement breeds quakes, tidal waves and the volcanic eruptions
that formed the islands themselves.
