Remembering the US-based civil defence training efforts of my childhood, I note that my adult children didn't have that experience as they passed through public schools. Instead, they had lock-down drills related to threats of humans with guns. Though that may be due to changes in perceived disaster risk, the training was a top-down decision in both cases, leaving the communities at risk regarding natural disasters which actually occurred. I suspect that a generational "forgetting" is a distinct possibility both from the top down and the bottom up, even in empowered communities whose capacity is built in areas of disaster management. When we depend on human capacity, that is a risk that isn't often mentioned.
