Drones are now being used by researchers, notably those at the University of Montana, to forecast how to respond to disasters, particularly forest fires. Drones are equipped with sensors that can monitor wind speed and direction, position, location, humidity, and temperature. Major utility companies are looking into how technologies like drones and artificial intelligence may help to lower the likelihood of future fires and for infrastructure assessment to help minimize fire risk. Drones are now being used by California's emergency services to help find forest fires, which can help determine the kind and quantity of supplies needed on the site. Drones can be equipped with thermal detection sensors, which utilize infrared light to identify heat signatures and aid first responders find hotspots for fires.
