In Europe and elsewhere the economically feasible water resources have been greatly developed until the 1970s. nH'e?>x~e
Although large dams belong to the first structures, which have been designed systematically against earthquakes @R"JW\bd
since the 1930s, the seismic safety of these dams is unknown, as most of them have been designed using seismic VUGmi]qd
design criteria and methods of analysis that are considered obsolete today. The fact that no major dams have K Hu+9eX

the impression that well-designed dams are safe against earthquakes. We need to re-evaluate the seismic safety ~&_z2|UXp
of existing dams based on current state-of-the-art practice and rehabilitate existing dams if necessary. vHc%z$-d
Additionally, there are a large number of smaller dams, especially earth structures, which were built for PfD.:amN7
