This paper describes the deformation and collapse of a liquid column due to a shock wave and shock-wave-induced high-speed air flow. Experiments were conducted using a pressure-type shock tube equipped with a holographic interferometer. A shattering process of the water column is observed using holographic interferometry. The shattering process is characterized by three stages : 1st stage, deformation of a water column ; 2nd stage, appearance of crests at the separation point of a boundary layer over the water column and onset of surface waves ; 3rd stage, breakup and atomization due to the surface wave. Time variations of the mass, and longitudinal and transverse diameters of a shattering water column are presented for incident shock wave numbers Ms=1.18, 1.47 and 1.73. The structure of a flow around the shattering water column is discussed in detail.
