We experimentally studied the behavior of a bubbly flow under an earthquake vibration. We focus on the effects of vibration on the bubbly flow in the components by performing visualization experiments of the vertical bubbly flow in a rectangular water tank on which a sinusoidal vibration was applied. As a result, bubble behaviors were affected by oscillation; the cycle of the bubble lean angle was almost the same as that of oscillating table velocity in the low frequency, and response characteristics of bubbles change by acceleration and table's frequency.
