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.
