Remotely Visible Width and Discontinuity of 50 Tornado Damage Paths through Forested Landscapes

Abstract: Tornado damage-path width is a necessary component for calculation of area impacted, which allows estimation of hazards. To date, rarely has variation in damage path width or path discontinuity been a focus. In this paper, using a damage threshold of >25% canopy damage, we quantify width and discontinuity in 50 tornado paths in forested areas. Tornado-path starting and end points were overlaid on Google Earth imagery obtained ≤24 months after the tornadoes, and damage-path width (or absence of damage) was m… Show more

“…Recent advances in remote sensing have made it possible to document tornado tracks in unprecedented detail, overcoming previous challenges in accurately measuring tornado forest damage (Burow et al., 2020 ; Cannon et al., 2016 ; Kingfield & de Beurs, 2017 ; Molthan et al., 2014 ; Rodríguez & Bech, 2020 ; Zenoble & Peterson, 2017 ). Case examples demonstrate the significant impact of exceptional tornadoes on forest structure.…”

“…The frequency distribution of tornadoes by EF intensity scale appears to follow a power law in which the number of EF2 tornados is approximately half the number of EF1 tornadoes and so on (Elsner, Jagger, Widen, & Chavas, 2014 ). While low intensity tornadoes (F0 and EFO) are capable of stripping foliage and breaking small branches, they seldom result in windthrow or canopy damage that is visible by remote sensing (Zenoble & Peterson, 2017 ). EF1 (F1) tornadoes can uproot or topple mature trees, while EF2 (F2) and EF3 (F3) events can snap them off.…”
