This material is extracted from Washington Public Power Supply System, Preliminary Safety Analysis Report, WPPSS Nuclear Project No. 1, 1300
MW Nuclear Power Plant, Vol. 2A.
Vol, 2A has a submittal letter dated September 19, 1977. We have copy number 82. The letter states that Amendment 23 is the response of WPPSS to a request to
re-evaluate the 1872 earthquake.
Vol. 2A contains the following:
- 2R-A "Report of the Review Panel on the December 14, 1872 earthquake" by Coombs, Milne, Nuttli, and Slemmons (excluding verbatim original accounts)
INCLUDES
- An assesment of the horizontal ground acceleration required to overturn a large rock located near Omak Lake, Washington (pp. 2RA D14-D20)
- 2R-B "A review of the North Cascade earthquake of 14 December 1872" by Woodward-Clyde
- 2R-C "Tectonic Evolution of the Pacific Northwest Precambrian to present", by Gregory A. Davis
- 2R-D "Geologic Studies in the 1872 earthquake Epicentral Region", by Shannon and Wilson
INCLUDES
- Detailed discussion of the various faults in the area that might be sources for the 1872 EQ
- 2R-E "Geophysical and Seismological Studies in the 1872 earthquake epicentral region", by Weston Geophysical
Scanned Items include:
- TABLE 2R B-2 A list of newspaper articles about the 1872 North Cascades Earthquake
- TABLE 2R B-4
This table presents Modified Mercalli Intensities for the 1872 North Cascade earthquake.
MMI values from studies by WPPSS (1977), Weston Geophysical (1976), Coombs et al. (1976), Puget Sound Power and Light/Bechtel (1977), Puget Sound Power
and Light/N. Scott (1977), and USGS(1977) are tabulated in alphabetical order by place-name. Figure 2R-B1, which follows the tabulation, is an "Isoseismal Map for
the 1872 North Cascade earthquake" provided by Woodward-Clyde, the authors of this section)
