Deterministic tsunamigenic earthquake hazard assessment for the northern coast of Egypt based on multi-scenario approach

Egypt’s northern coast can be considered a dynamic natural system like several coastal regions worldwide. While it provides many opportunities and resources, it may also pose significant challenges to the community, as the area is prone to land and marine-related geohazards (e.g., earthquakes, sea-level rise, land subsidence, storms, coastal erosion, and tsunamis). Also, the recent national census survey indicates that numerous assets, systems, infrastructures, and cultural heritage sites (elements under risk) are situated within the zone of hazards. Multi-hazard and risk assessments are therefore necessary to achieve national sustainable development plans. This study, in particular, focuses on tsunami hazard, which is defined here as the envelope (upper bound estimate) from a comprehensive set of possible simulated tsunami scenarios. The main aim of this work is to provide robust and conservative hazard estimates while considering the variability related to earthquake parameters. The ...
