The Colorado River Irrigation District in Mexicali has suffered extensive liquefaction of the water infrastructure. According to the wiki:
Soil liquefaction describes the behavior of soils that, when loaded, suddenly suffer a transition from a solid state to a liquefied state, or having the consistency of a heavy liquid. Liquefaction is more likely to occur in loose to moderately saturated granular soils with poor drainage, such as silty sands or sands and gravels capped or containing seams of impermeable sediments. During loading, usually cyclic undrained loading, e.g. earthquake loading, loose sands tend to decrease in volume, which produces an increase in their porewater pressures and consequently a decrease in shear strength, i.e. reduction in effective stress.This year's crops are mostly lost. I wonder how to rebuild the infrastructure to resist future earthquakes. The pic shows how the increased soil water pressure during an earthquake expulsed sewage manholes from the earth.
