Abstract

The aim of the present study is to assess the present geo-environmental hazards, both flash flooding and seismic activity in the western part of Gulf of Suez. Assessment includes the analysis of satellite images, topographical, geological and other ancillary geological data using GIS technology. GIS data integration and analysis, including morphometric, local seismic activity and structural data analysis indicated that the area is under threat from two types of geo-hazards. Morphometric analysis strongly supported the high probability of flash flooding in different sites within the study area. The structural lineaments, extracted from an enhanced ETM+7 image, showed that the majority of seismic activity is related to segments of the fault system of the Gulf of Suez and the Gulf of Aqaba. The seismic activity hazard was taken into consideration through the identification of the sources of events. Seismic activity in the study area markedly increases from north to south. The distribution of the seismic activity pattern and data analysis for the study area clearly exhibits the urgent need for an assessment and rehabilitation program to mitigate geo-hazard along the existing structures.
