Optical (camera-based) technologies can greatly assist in risk assessment. Potential applications are identified in this paper. Several field application examples are described, largely encompassing the areas of civil infrastructure monitoring. Since optical (camera-based) systems can be particularly powerful for monitoring both local and global movements within a scene or environment, natural hazards such as earthquakes are an important application area for these new technologies. It is observed that concepts from the methodology applied to general civil infrastructure systems are readily applied to other types of natural or man-made hazards. First, a clear definition of seismic risk assessment is provided. Subsequently, two important fields where cameras may be useful in seismic risk assessment are described. Specifically, the context of (i) early warning systems and (ii) post-earthquake assessment are addressed. An example of using the optical record from a series of large shake table tests is provided and the comparison with other methods discussed.
