![]() In conclusion, this research demonstrates the utility of point cloud data in identifying potentially dangerous trees and reducing the risk of fires. We also found that, although the probability of fire ignition is typically low under normal conditions, it is likely to increase at a wind speed of approximately 40.3 m/s. Our analysis showed that the main factor determining tree deflection is the ratio of the tree height to the trunk diameter. To conduct this study, we used airborne LiDAR data collected from Sonoma County in northern California and analyzed the behavior of a sample tree having a height of 19.2 m under wind loads. To address this gap in knowledge, we investigated the critical wind speed that heightens the risk of wildfires by calculating the distance between trees and wires. While most studies have focused on the tree encroachment around power lines during normal weather conditions, recent catastrophic fires have been caused by strong winds. To prevent such incidents, local safety councils have established minimum clearance regulations between trees and power lines. ![]() The incidence of wildfires caused by tree contact with high-voltage power lines has become an increasingly pressing issue in the United States.
