AK
Report and maps of
tsunami inundation
3 areas completed: Kodiak
and vicinity, Homer and
Seldovia, Seward
Signiicant challenge in obtaining
recent bathymetric and topographic
data of suficient quality to generate
accurate high-resolution DEMs for
inundation mapping
CA
Report and maps of
tsunami inundation
Inundations maps (131)
for emergency response
covering almost all risk,
populated areas within
California (+100 cities/towns;
15 coastal and 5 interior bay
area counties) completed
at 90 m grid resolution,
enhanced by 3 to 10 m DEMs
on shore
Inundation maps for several remaining
communities are planned. Evaluation
of 10 m DEM modeling will determine
if another generation of maps are
needed. Additional work will include
evacuation and possible creation of
tsunami hazard maps for land-use
planning.
HI
Report and maps of
tsunami inundation
Evacuation maps from
1-D modeling for state
completed; Updating 28
communities with 2-D
modeling; Oahu modeling/
inundation mapping
complete and Hawaii
in progress; Expected
completion Dec 2009
Initial 725 of 1,500 km of coastlines
completed with 1-D modeling;
Credible worst-case scenarios used;
2-D numerical modeling of ive major
trans-Paciic tsunamis during the past
century under way; Validation with
historical run-up records; Identiied
10 locations of the current evacuation
maps that may need modiication
OR
Report, maps, GIS
projects
Detailed hazard maps for
10 communities completed;
Tsunami evacuation zone
maps for 23 communities
completed
Distinguish between a tsunami caused
by an undersea earthquake near the
Oregon coast (local tsunami) and an
undersea earthquake far away from
the coast (distant tsunami)

Islands pending

Coast
