Tectonic Setting of Southwest Alaska

Seismicity in Southwest Alaska is very sparse. Known faults include the Iditarod-Nixon Fork and the western Denali Fault. Neither fault system has documented historical or Holocene earthquake activity. On average this region produces one M4-5 earthquake every other year.
