Washington, DC: United States Geological Survey/USGS/Government Printing Office/GPO, 1982. Softcover. Item #39387
Because of the frequent recurrence of moderately strong earthquakes, this region has been under intensive study for many years by seismologists, geologists, and engineers of the U.S. Geological Survey and other research institutions. 451 pages with photographs, seismic records, tables, charts, sections, and references. A separate hardcover folder with the four folded plates, all fine, is present. U.S.D. library stamps on the covers and a few pages. No other library markings, pockets or plates were ever present. Both very good plus.
