Rockfall characterisation and structural protection – a review [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2011
Abstract. Rockfall is an extremely rapid process involving long travel distances. Due to these features, when an event occurs, the ability to take evasive action is practically zero and, thus, the risk of injury or loss of life is high. Damage to buildings and infrastructure is quite likely.
