This article describes a current topic of cavitation bubble dynamics, highlighting interactive problems such as the interaction between a bubble and a boundary, the bubble –bubble and shock wave bubble interactions. Much investigation associated with these has been reported, in which the nonspherical motion of bubbles, leading to bubble migration and liquid jet formation, and impulsive pressures generated during the last stage of bubble collapse as well as pressure amplification due to shock wave-bubble interaction were discussed. It is mentioned that a cavitation bubble can take various modes in the motion depending on physical conditions, especially on the dynamic response of a boundary and a nearby bubble and characteristics of a shock wave emitted from an adjacent bubble.
