Seismic risk assessment in Jaramana city using GIS

Abstract

This study aims to assess the seismic risks of Jaramana city using geographic information systems to reach a sustainable reconstruction process after taking all the criteria into account such as the criteria of ground motion and the criteria of the fundamental period and amplification factor of the soil and the criteria of the ground failure such as liquefaction, land-sliding, surface fault rupture and cavitation as well as the criteria of buildings and population density. The results showed that the values of the fundamental period of soil ranged between 0.62 and0.64, and the value of the amplification factor ranged between 1.7 and3.5, and they showed high risk for large parts of the city, especially in slums and areas with buildings with 6-7-8 roofs. This study recommended the necessity of reconstruction the slums and taking into consideration the fundamental period of the soil in granting building permits and adjusting the construction processes in accordance with the Syrian Arab code.
