However, having experienced harassment and assault in the previous emergency shelter, they may choose not to evacuate this time.<\/li>\n<\/ul>\n\n\n\n <\/figure>\n\n\n\nSign indicating a wildfire evacuation route in Boulder, Colorado, USA. While having signs is useful, they do not guarantee that people will act accordingly; for instance, previous negative experiences during evacuations could deter individuals from doing so.

Some lack options for risk reduction, while others consciously choose not to exercise available options. Both situations should be considered by people and institutions working on preventing disasters.<\/p>\n\n\n\n
Distinguishing correlation vs causation is important to understand disasters<\/h2>\n\n\n\n Scenarios such as the ones above help to understand people and institutions who reduce risk, those who have no options for adopting risk reduction measures, and those who have options yet make conscious decisions not to exercise those options.<\/p>\n\n\n\n
In these analyses, hazard strength is often poorly correlated with disaster severity, since hazard strength is usually not the cause of the disaster or its severity. Understanding concepts such as correlation and causation ensures that the real causes of disasters are accepted, so that actions redress the real causes.<\/p>\n\n\n\n
So what can help with risk know-how?<\/h2>\n\n\n\n For me, a fundamental concept of risk know-how becomes that the phrase ‘natural disaster’ should not be used. Disasters do not come from nature, rather resulting from individual and collective choices or lack thereof.<\/p>\n\n\n\n
