5 California has the highest earthquake hazard
level in the United States, as indicated by
geological hazard maps. Why might scientists
use geologic hazard maps?
A. to determine areas that are at higher risk
from a geologic hazard
B. to predict when an earthquake might occur
C. to identify stress-related strain in rocks
D. to monitor gas seepage from strained or
fractured rocks
High earthquake hazard does not mean high risk. Also, while you can’t change the underlying earthquake hazard, you can reduce earthquake risk by managing the built environment.
