The correct answer is true. As many as 90 percent of wildland fires in the United States are caused by humans, primarily through campfires left unattended, burning of debris, negligently discarded cigarettes and intentional acts of arson. The next most common source of wildfires is lightning. Keep in mind that there are many natural factors, such as vegetation and extreme heat or drought, which can combine with human factors to increase fire activity and risk. The USGS provides tools and information before, during and after fire disasters to identify wildfire risks and reduce subsequent hazards, while providing real-time geospatial support for firefighters during the events.
