Abstract: On October 12, 1992 a moderate earthquake MB = 5.9 (Ms = 5.2) occurred about 18 km southwest of the center of Cairo and resulted in significant damage to numerous old and/or poorly constructed structures. Soil liquefaction associated with the occurrence of large sand-boils was observed close to the epicenter. In this study, the earthquake characteristics, along with typical examples of induced damaged, are discussed. The observed liquefaction mechanisms provide valuable information on the seismic response of Nile deposited alluvial soils, which cover much of the inhabited area of Egypt.
