Abstract: The characteristics of the dam strong earthquake are described, as well as the difference between the dam strong earthquake monitoring and general earthquake monitoring and the developing trend of the strong earthquake monitoring. It proposed to give the warn of earthquake damage by the strong earthquake monitoring technology. The index and threshold of the dam earthquake damage are given. The various measures are proposed for the various classification of earthquake damage warning.
