Abstract: The bentonite clay has been found with a wide area of about ten thousands of square kilometers the behavior of which has been paid great attention for the reason of its damage to engineering structures. However, in this context, a great deal of seismol-ogical research has been overdue.Following available data from the Nanjing seismological station, this paper stresses the importance on this clay in ongoing seismological survey.
