Tectonic Setting of the Brooks Range

Seismicity in the Brooks Range is characterized by intraplate earthquakes associated with mountain building and crustal reorganization. A broad earthquake band extends from northeast of the Brooks Range toward the Beaufort Sea. Earthquake source mechanisms comprise a mixture of strike-slip and normal faulting events, indicative of north-northwest compression and northeast extension. Together with the North Slope, this seismic zone produces a few magnitude 4-5 earthquakes per year.
