We constructed a pre-computed tsunami
database for six areas located along the Pacific coast of Nicaragua, which
could be categorized as tsunami-susceptible areas. The database was created
from a set of tsunami waveforms and inundation models from several fault model
scenarios of Mw 7.0 to Mw 8.2 with an increment of 0.2 on the magnitude scaling.
We evaluated the reliability of Near-field Tsunami Inundation Forecast
(NearTIF) algorithm following the methodology suggested by Gusman et al. (2014)
using the 1992 Nicaragua tsunami earthquake (Mw 7.6). The linear tsunami
propagation and nonlinear inundation computations were performed by using
TUNAMI code developed by Tohoku University. Finally, we applied the NearTIF
algorithm to evaluate the calculation time of the best solution for tsunami
inundation forecasting in the areas. We adopted 70 fault model scenarios (FMS)
and found tsunami waveforms from the database which share similarities with
those from numerical forward modeling (NFM) of the 1992 El Transito-Masachapa
tsunami earthquake. We extracted the inundation map associated with the best
FMS from the inundation database for the comparison with the inundation area
generated from the NFM.
