Abstract: Many past earthquakes have witnessed failure of liquid storage tanks in various ways. Sloshing action is one of major kinds of them. Hence it becomes essential to detect the pattern of surface wave and use preventive measures. As we know that the mass of water can be thought of as two parts, impulsive at lower depth and convective at upper depth. This analysis work was primarily focused on convective part. In this experimental study, the earthquake induced waves were analyzed with a representing tank model using shake table facility at DTU, Delhi. Further, the wave patterns and seismic parameters were determined analytically, and results were compared. The work gives a fair idea to study the seismic behavior of liquid storage tanks.
