Earthquake is the most destructive natural disaster which may not take long more than some seconds and during this short period of time, there may be serious casualties. What happens then and its extend is directly relevant to the earthquake acceleration, its depth and power. During the current century, constructions of many dams are fulfilled and many others will be constructed maybe in the areas in which serious earthquakes are predicted. Since more than a million of people are living in the downstream of these dams, it is a vital issue that further attention be taken into account for the construction and monitoring of these Dams against earthquakes. For the evaluation of stability and reliability of Dams, it is needed that their seismic behavior be completely studied and all their weak point be cleared. It seems that the best solution for this regard is the monitoring of Dam's health. This process contains structure's monitoring or its mechanical systems during a special period of time by use of special monitoring sensors. This will provide us with important data which will be used in the future analyses. Prediction of a failure will be much easier and emergency action plans will be defined before the occurrence of a phenomenon. The main purpose of this article is to evaluate the seismic behavior of CFRD and ECRD dams by use of different methods such as Centrifuge test; accelerograph and laser sensors equipped with high speed cameras to monitor all movements (vertical and horizontal).
