Behavior of buried tanks during an earthquake, according to the application and its importance after the earthquake, the issue is a vital and important. This led to different parts of the seismic analysis of tanks has been buried by several researchers. In this paper, one of the essential and important part of the process tanks buried seismic analysis, ie the fluid and structure interaction during earthquakes has been considered To enter thus the dynamic pressure on the reservoir and its interaction effects with regard to the effect of fluid and structure interaction is evaluated. For this purpose, seismic behavior of cube shaped tanks buried in the soil according to the three-dimensional models to aid software Abaqus Is investigated. In the process fluid as a continuous medium, and Non-rotating assumed incompressible and equations of motion, based on differential equation governing the hydrodynamic waves is considered. Finally, the effect of important parameters such as the type and height of fluid in the various models under the effect of an earthquake record as a time history has been evaluated.
