ShakeMap was designed primarily as a rapid response tool to portray the extent
and variation of ground shaking throughout southern California immediately following
significant earthquakes. The system now runs throughout California as well as in the Salt
Lake City and Seattle areas, and it is being expanded to populated, seismically active
regions nationally as resources permit. For rapid response, ShakeMap ground motion
values are used for emergency response and loss estimation, assessment of damage to the
lifeline and utility networks, and for providing information to the general public.
However, ShakeMap can also be used as a pre-earthquake planning tool by generating
ground motion estimates for a suite of potential earthquake scenarios. Estimates based on
earthquake scenarios can provide a firm basis for loss estimation on a regional scale as
well as provide utilities and other users a means of evaluating their emergency response
capabilities. This paper will examine the practical applications of ShakeMap in
emergency response, engineering, planning, training, and public education considering
both current and future applications.
