Unsaturated Volcanic Tephra and Its Effect for Soil Movement in El Salvador
Original language description
In El Salvador during the rainy season or when major earthquakes affect the area, processes like mass movements, liquefaction, erosion and floods affect the territory leaving environmental, social and economic damages. The volcanic tephras called "TierraBlanca Joven" (TBJ) which is a product of the last plinian eruption of the Ilopango Caldera are the more problematic region in the Metropolitan Area of San Salvador. In El Salvador during the summer and rainy season the groundwater level remains low inmost of the areas, this means that the soils in the country are unsaturated and there are capillary forces that act on the soil structure making that an ?apparent cohesion? (suction) improve the strength of the soil; this circumstance makes that the slopes are almost vertical and temporally stable, but will collapse when wetted or during seismic events. To that problematic is possible to add that the majority of the water pipelines are in bad condition and when they fail is possible to e
