Abstract: Underground pipeline safety is a concern among civilians in populated urban cities. Due to the potential for considerable damage from underground pipeline leakages, it is critical to identify potential risk areas. This study developed a simplified risk value using risk assessment software (ALOHA) and geography information systems (SuperGIS and Surfer) to produce potential risk maps for underground pipeline leakage in a major urban city. A risk assessment of areas affected by underground pipeline leakage was performed for vapor diffusion, thermal radiation from combustion, and overpressure from an explosion. The results are applicable to disaster management departments and agencies in highly populated cities.
