Natural hazards, such as earthquakes, hurricanes, floods, landslides, wildfires and droughts are increasing in frequency and intensity, in large part because of climate change (M. Coronese et al. Proc. Natl Acad. Sci. USA 116, 21450–21455; 2019). In 2022, at least one event occurred every day, according to data from EM-DAT, an international disaster database. And a 2021 report from the United Nations Food and Agriculture Organization stated that the “annual occurrence of disasters is now more than three times that of the 1970s and 1980s” (see go.nature.com/43pmeke).
But natural-hazard events don’t necessarily have to escalate into widespread disasters. Even though they are more common today than they were in the past, the number of deaths from them has drastically declined. In 1920–29, for example, more than 8.5 million people died globally as a result of natural disasters, compared with just over 503,000 in 2010–19, according to data from EM-DAT. This can be attributed partly to improvements in disaster risk reduction and preparedness measures. Nature talked to five disaster researchers about how they are working to reduce the risks and impacts of natural-hazard events.
