    In this paper we present two examples of the use of ultrasonic measurements for the assessment of damage localisation in rocks deformed under laboratory conditions: (1) using multiple point-to-point velocity measurements during a loading experiment on a soft rock with simultaneous full-field strain measurement, which permits a link to be made between velocity changes and deformation; (2) using ultrasonic tomography to obtain full-field measures of velocity in specimens of a Vosges sandstone with localised shear-band features, in which the strain localisation is found to be coincident with localised damage (velocity reduction).
