Map 1. Composite Relative Earthquake Hazard Map
advertisement
Maps 2 to 4 are simplified versions of the amplification of ground motion, liquefaction and earthquake-induced slope instability maps. These maps have been simplified from Geoscience Maps 2000-3a, 3b, and 3c by combining the very low and low ratings and the high and very high ratings to produce a three-class rating system – low, moderate and high.
