Overview of Slope Stability, Earthquakes, Flash Floods and Expansive Soil Hazards in the Republic of Yemen

Yemen has harsh natural conditions that increase certain geological processes more than other regions, leading to a variety of geological hazards. Yemen’s typical topography is distinguished by coastal plains of the Red Sea and cliff foothillls, followed by mountains of the Arabian Shield. These types of geological hazards can be classified into slope stability, earthquakes, flash floods and expansive soils. The current literature review presents a description backed with examples of the certain geological hazards in Yemen. The obtained results indicate that further consideration and thought are highly required for semi-arid regions. National and foreign organizations have to collaborate together with other individuals to maintain the adjusted environmental system and reduce the potential geological hazards. Therefore, mitigation measures should be implemented to avoid and minimize these geological hazards.
