Summary

This data release provides access to a low-altitude, aeromagnetic survey of a part of south-central Washington and north-central Oregon. The survey extends from the Blue Mountains westward to the Cascade Range and covers the Oregon cities of The Dalles, Hermiston, and Milton Freewater and the Washington cities of Richland, Pasco, Kennewick, and Walla Walla. Data were acquired during the summer of 2010 by Goldak Airborne Surveys working under contract to the U.S. Geological Survey. Total magnetic field values were acquired using a fixed-wing aircraft flown at a target elevation of 150 m above terrain (305 m over urban areas) and along flight lines and tie lines spaced 400 m and 4000 m apart, respectively. Flight lines were directed [...]

Purpose

These data were acquired to support earthquake hazard investigations and geologic mapping of the greater Pasco area. The primary focus was the eastern portion of the Yakima fold and thrust belt, including the Rattlesnake Mountain, Horse Heaven Hills, and Columbia Hills anticlines and their associated faults. Initial interpretation of these data are presented in Blakely (2014) [Blakely, R.J., Sherrod, B.L., Weaver, C.S., Wells, R.E., and Rohay, A.C., 2014, The Wallula fault and tectonic framework of south-central Washington, as interpreted from magnetic and gravity anomalies: Tectonophysics, 624-625, p. 32-45. http://dx.doi.org/10.1016/j.tecto.2013.11.006] and Blakely (2012) [Blakely, R.J., Sherrod, B.L., Weaver, C.S., Rohay, A.C., and Wells, R.E., 2012, Tectonic setting of the Wooded Island earthquake swarm, eastern Washington: Bulletin of the Seismological Society of America, v. 102, p. 1786-1785. https://doi.org/10.1785/0120110189].
