Central Alaska, United States is the Flinn-Engdahl region number 1. It is part of the seismic region 1 (Alaska – Aleutian Islands Arc). The region is rectangular and reaches from 161° to 141°W and from 65° to 62°N. It verges on Southern Alaska, United States to the south, on Southern Yukon Territory, Canada to the east and on Northern Alaska, United States to the north and to the west. It is seismically active, the last major earthquake struck it on November 3, 2002, with a magnitude of 7.9. The area lies within the fold and thrust belt of the Alaska Range. Earthquakes are rare but can reach high magnitudes. They occur usually in shallow depths and therefore bear a high potential of damage. However, since the area is very poorly populated, population exposures are mostly very low.
