Ground Damage Assessment from Tornado-Borne Projectiles
Tornados often create and transport large amounts of debris that can be ejected at high velocities. There have been empirical and theoretical studies conducted on missile transport and impact, but ground damage from tornado-borne projectiles has not been well documented in the field. This paper summarizes the evidence and extent of ground damage from tornados and proposes a method for field data acquisition and assessment. Impact velocities of projectiles can be estimated using field measurements of ground deformations coupled with projectile and soil properties. Ground damage has the potential to adversely affect subsurface infrastructure if the penetration is deep enough to strike a buried pipeline or if the ground impact transfers sufficient energy to induce local settlement around a buried pipeline. With reliable data, ground damage assessment can be considered for inclusion as part of the Enhanced Fujita Scale for tornado classification.
