Summary
Guatemala Earthquake 1976. One of many large cracks in a delta at Lake Amatitlan (20 kilometers south of Guatemala City) opened as a result of Earthquake-induced liquefaction of a near surface layer of saturated pumice sand and lateral spreading of the surficial deposits towards the lake. Such cracks caused serious damage where they intersected structures such as the one in the foreground. The front portion of the house in the background sank into the liquefied sand, tilting the brick chimney. Photo by S.B. Bonis, Guatemala Geological Survey, 1976.
