Liquefaction potential along the coastal regions of Karachi

This paper investigates liquefaction resistance of the coastal belt of karachi stretched over 38 kms,the assessment is based on the scattered standard penetration test data of 120 bore logs. the liquefaction potential has been evaluated using simplied procedure developed by seed and idriss (1971) and modied by youd et al. (2001). the results of analysis are transformed into maps,which are expected to serve as general guidelines for effective town-planning,designing efcient mitigation systems,ground-failure vulnerability and for future microzonation studies. this study endeavours to provide the basis on which a comprehensive microzonation map of karachi can be developed after some modications. © 2015 national centre of excellence in geology. all rights reserved.
