Title: Sinking MASS: Sustainable Water Use Practices for a City Plagued by Sinkholes
Authors: McGinley, Laurie
Keywords: Metropolitan Area of San Salvador
Issue Date: 2011
Abstract: Sinkholes in MASS are caused by five factors • Population growth: MASS experienced an unexpected surge in population around their civil war from 1980-1992 • Tierra blanca joven (TBJ): MASS is built on 50cm - 50m of fine, silicate volcanic ash • Hydrological systems: Both human made and natural systems easily erode TBJ • Maintenance: The city is unable to keep up with increasing maintenance as pipes age • Earthquakes: About 20 earthquakes of medium intensity are felt annually in El Salvador. Earthquakes crack water pipes.
