Abstract

Soil liquefaction is among the secondary earthquake effects. This phenomenon, which was widely seen in Astaneh-ye Ashrafiyeh during the 1990 Manjil-Rudbar earthquake, led to considerable damage. The present study was conducted to assess the future re-liquefaction hazard and risk and prepare liquefaction hazard map of the study area. For this purpose, in addition to the available geotechnical data, 20 new boreholes were excavated and both in site and laboratory experiments were conducted on 100 soil samples. To prepare liquefaction risk zonation map, the structural condition and the value of 1,000 residential and commercial units, and lifelines were evaluated. Next, using the risk matrix model, the risk map of the Astaneh-ye Ashrafiyeh City was prepared. The results show that although liquefaction history of the area has reduced liquefaction risk in some parts of the city, the risk was increased in the central parts of the city due to the traditional texture of the city and dense buildings. Moreover, the presence of a hospital and governorate building in the central part of the city poses serious difficulties during transport of the injured and quake-stricken individuals and communication access lines of the northern Iranian provinces during the crisi
