EIS-0220-SA-01: Supplement Analysis

Seismic Activity on H-Canyon

Incorporating up-to-date seismic data, WSRC completed a detailed evaluation of the likelihood of a severe earthquake and the estimated resulting structural damage of H-Canyon. This evaluation indicated that a severe earthquake capable of producing structural damage comparable to that described in the IMNM EIS would not occur more frequently than once in 5500 years. That is less frequent than the severe earthquake occurrence assumed in the IMNM EIS (1/5000 years).
