Abstract/Summary:
The goal of this study was to give an estimate of the number of buildings, the area of these buildings, the rebuilding cost of these buildings, and people that are at risk, of various potential tsunami run-ups in Fujairah city in the United Arab Emirates. Since the seismic activity has been increasing in Fujairah City and its surrounding areas ( Arabian and Omani Gulfs) and due to the lack of tsunami event records in the region, it was necessary to conduct this research to evaluate tsunami run-up risk levels in Fujairah city. A numerical model was used that included the Digital Elevation Model (DEM) to represent the different tsunami run-ups in the city, based on the elevation. Almost all of the buildings in the city were digitized using IKONOS satellite imagery which was then placed over the numerical model to estimate the number and the areas of the buildings at risk in the tsunami run-up zones. Moreover, Fujairah's population was added to the model to estimate the number of people at risk of tsunami run-up in each level. Several run-up risk maps were created to represent the buildings and population at risk of tsunami run-ups, in addition to graphs that illustrate the relationships between risk and the distribution of the buildings and the population.;There was a noticeable relationship between the number and the area of the buildings, their rebuilding cost, and the number of people at risk of tsunami, and the run-up levels; the numbers within these variables increase if the run-up levels go up. Significant findings included: the increase in the number of buildings at risk in tsunamis of 6 -- 10 and 11 -- 15 meter run-up scenarios, due to the concentration of the residential and retail buildings in these run-up zones. Significant findings for the rebuilt cost were that the rebuilding cost of the buildings with one to three stories is higher than that of the buildings with 10 -- 30 stories, due to the large quantity of the former. Since Fujairah is a coastal city, almost 44% of its population lives within 2 km from the coast, which puts the population at risk for 6 -- 10 or 11 -- 15 meter tsunami run-ups.;Key words: UAE, Fujairah, tsunami, risk, hazard, rebuilding cost,...
