Discussion of "Liquefaction-Induced Lateral Spreading at Izmit Bay during the-Kocaeli (Izmit)-Turkey Earthquake" by K. Onder Cetin, T. Leslie Youd, Raymond B. Seed, Jonathan D. Bray, Jonathan P Stewart, H. Turan Durgunoglu, W. Lettis, and M. Tolga Yilmaz

The authors' extensive work on estimating liquefaction-induced lateral ground displacements during the Kocaeli (Izmit) Turkey earthquake is commendable. The paper has given the discussers an opportunity to present to the discipline another method to estimate the extent of liquefaction-induced lateral spread. The procedure has its genesis in the earlier work of the discussers (Phatak and Dhonde 2003; Phatak et al. 2004).
