Development of Oil and Gas Industry leads to significant amount of storage tanks being built in earthquake-prone zones. During seismic events, tanks suffer damage of different types. This article discusses main types of defects and failures, their causes, and applicability to each kind of tanks. A classification of these damages in accordance with two levels of assessment of the consequences of earthquakes adopted in regulatory documents of Russian Federation is proposed. Based on the results of the analysis, factors that ought to be taken into account for developing the seismic procedure of storage tanks are identified.
