A rockfall is a type of fast-moving landslide common in mountain areas worldwide (Cruden and Varnes, 1996).
An individual rockfall is a fragment of rock detached from the bedrock along new or preexisting discontinuities (e.g., bedding, joints, fractures, cleavage, foliation) by creeping, toppling, sliding, or falling, that falls along a cliff, proceeds down slope by bouncing, flying, tumbling, or rolling. A rockfall stops when it has lost enough energy through impacts or by friction (Fig. 1) (Dorren, 2003; Guzzetti and Reichenbach, 2010).
