AB: We developed Tsunami hazard maps in four areas with an extension of 30 km each along Pacific coast of Nicaragua, based on the observed worst historical Tsunami inundation record, assuming that the future Tsunami earthquake with similar magnitude would occur again in these areas as the worst case. This is a part of the result obtained by the technical cooperation "The Study for Establishment of Base Maps for GIS in the Republic of Nicaragua" executed during the year from 2004 to 2006 by Japan International Cooperation Agency with INETER as a counterpart agency upon the request by the government of the Republic of Nicaragua. By integration of available topography information that exist in various institutions in Nicaragua and additional study, we developed topography model using 2700m, 900m, 300m, and 100m sized grid system. The program used for the simulation was based on the one developed by Tohoku University and published by UNESCO (1997). Historical records of Tsunami in Nicaragua were documented since mid-19th century. Among them, the 1992 Nicaragua Tsunami earthquake was the largest one. The methodology used here was verified using tide gauge records, inundation records, and inundation areas observed during the 1992 Nicaragua Tsunami. Further, "the worst case scenario" for each one of the four study areas was estimated moving the same dimension of fault along the coast. Finally, Tsunami hazard map was made that visualizes the spatial distribution of simulated maximum wave height, maximum inundation depth, and elevation of non inundated area. We expect that the resulted maps will serve as basic reference for Tsunami disaster prevention planning by related Nicaraguan governmental institutions, local government in charge, and communities etc.
