The Oceanographic Institute of the Ecuador Navy (INOCAR) is currently working on the development of a tsunami database to determine tsunami maximum height as well as time of arrival in different cities along the coastline. The main objective is to rapidly assess the possible consequences of the occurrence of a local tsunami.
This study proposes the construction of a tsunami inundation database in Jaramijó city as an example to be replicated in other cities. The short-term objective is to link inundation maps to INOCAR’s tsunami database when disseminating local tsunami warning bulletins.
The TUNAMI-N2 code is used for simulation with bathymetry and topography data from GEBCO and INOCAR. A total of 564 scenarios were modeled considering four magnitudes (Mw = 9.0, 8.5, 8.0 and 7.5) at depths of 5, 10, 15 and 20 km.
The worst-case inundation scenario is found when modeling a Mw 9.0 earthquake at a depth of 20 km. This case could be taken as an example to work on a tsunami contingency plan in Jaramijó, considering that the worst tsunami scenario on record occurred in 1906 when a Mw 8.8 earthquake occurred in the northern sea border of our territory.
