We have all learnt with great anguish and sorrow the earthquake that shook the Mexico city and the tragedy that followed. From the photographs rhat appeared in the papers, it is seen that some structures, withstood the earthquake while some in the near vicinity crumbled down. This reatly calls for in depth critical review of the design including detailing that went into these structures and what made the structures fail when the structures nearby were standing. Behaviour of structures in earthquakes have generally shown that structures in which the state of the art design and detailing practices have been followed are less vulnerable and also in many cases withstand severe earthquakes. This is the result of scientific post earthquake investigation carried out by experts leading to continuous review of state of art by the institutions like the School of Earthquake Engineering. It would be interesting to know how hydraulic structures located near about Mexico city have behaved, as it may have a considerable implication on the designs of hydraulic structures.
