Conceptual diagram of the intersection of earthquake load and soil liquefaction resistance capacity. Areas where load exceeds capacity result in liquefaction ground failures. On the Delta River, the falling capacity is punctuated by abrupt inputs of poorly sorted material from side entering canyons. These inputs elevate the resistance capacity of the soil above loads imparted by the Denaii Fault event.
