CHAVEZ, José A et al. Engineering geology mapping in the southern part of the metropolitan area of San Salvador. Rev. Geol. Amér. Central [online]. 2012, n.46, pp.161-178. ISSN 0256-7024.

The use of classic geologic maps, where geological layers are grouped according to their age or origin, makes difficult the interpretation and use for civil engineer design or urban planning to people without deep knowledge in geology. Due to this reason engineering geological mapping has been carried out in the southern part of the Metro- politan Area of San Salvador using the stripe method. The objective of the methodology is that geological information, geological hazards and geotechnical recommendations as well, can be represented and grouped depending on the intrinsic characteristics of each zone. This information can be easily interpreted for urban planners, private builders and government agencies. The weakness in the compilation and research of geological and geotechnical information in El Salvador, are some of the reasons for the current problems that experiment the region, indicating the importance of improving risk management, as well as soil and rocks mechanics
