Not listed for Hawaii are two additional maps in progress for the Hilo and Kahului area funded by NASA's
Solid Earth and Natural Hazards Program.

Many of these Oregon maps cover populated regions that lack Census 2000 designated communities.

continues to independently conduct its own inundation modeling efforts. In doing so, each
NTHMP state member uses its own choice of tsunami source, bathymetry, topographic data,
and numerical code for the hydrodynamic simulations (Table 2.3).
Under the recently adopted NTHMP strategic plan (National Tsunami Hazard Mitiga-
tion Program, 2009a), the MMS plans to address these issues through developing of national
guidelines and an approval process for inundation mapping, as well as establishing priorities
of areas to be mapped. However, at the time of this committee's evaluation (2010), little
