This study compares various seismic isolation methods used to reduce the damage caused by impulsive and oscillating impacts on liquid storage tanks during earthquakes. In the research seven models were created, for the reference model no seismic isolation element was used, three models used different rubber bearings of varying hardness as the seismic isolation element and three models used dampers together with rubber bearings of differing hardness. Implementing a system of seismic isolation is very important for both the economy of a country and the environment of countries that are located in zones of high seismic risk. The Nonlinear time history analyses of the models were performed in accordance with the data from the, El Centro (USA), Northridge (USA), and Izmit (Turkey) earthquakes. The way in which the models reacted to the impact of seismic resonance differed according to the elements used. The comparison of the results show that using rubber bearings and dampers can protect the tank systems from the destructive effects of earthquakes.
