I may be missing something here, so please do correct me if I have misunderstood.
Does this term refer to collecting information (data) on damage and losses caused by disasters? Or are we referring to the loss of data caused by disasters? So, for the latter, I am thinking about flooding or fire that damages a data storage center and results in a subsequent loss of the data stored in the center.
Both of these seem important to me, I'm just not quite sure which of them the term proposed new term is referring to.
