The correct answer is all of the above. Once the smoke clears, the danger is not over. Secondary effects of wildfires can be equally devastating. These include debris flows, dust storms, invasive species, erosion and changes in water and air quality. Awareness of these secondary effects is critical to public safety. As fires are contained, USGS scientists help to assess their aftermath to guide the rebuilding of more resilient communities and the restoration of ecosystems.
