Datasets of structural damage and regional damage due to past earthquakes are not only useful to know the actual state of each event but also effective for strong ground motion predictions and damage mitigations of future earthquakes. In this paper, several considerations are illustrated concerning strong ground motion research and data processing analysis. Especially, the activity to make research results contribute to society is discussed based on three examples of earthquake damage data analysis. The examples shown here describe that the well known notion in general, what is called common knowledge, does not necessarily have high reliability, and that the lack of confirmation of the data accuracy misleads the conclusion of research results beyond common sense. From these examples, the importance of an empirical research policy as well as a reasonable research policy is discussed. And it is pointed out that the information exchange among the researchers in various fields will be very effective for the development of the strong ground motion research.
