Aleutian Earthquakes

Map of earthquake epicenters greater than magnitude 3.0, colored by depth (1889 to present). The Aleutian arc volcanoes (black triangles) form above the subduction zone where the Pacific plate reaches a depth of 100 km (where the earthquake epicenters transition from red to purple). The Pacific plate motion is to the northwest at rates between 50 and 64 mm per year. Earthquake depths beneath Kenai Fjords National Park are primarily between 0 and 40 km.
