Description :
Studies of rockfalls and block slides provide insight about shaking hazards in alpine mountains subject to earthquakes. Large samples of the longest axis of the largest on each block can be used to identify regional landslide events; the coseismic rockfall lichenometry model can be used to date and locate prehistorical earthquakes, document regional frequency of earthquakes, and describe regional patterns of seismic shaking. Determination of colonization time, great-growth phase, and especially uniform phase rates of lichen growth are essential for dating regional landslide events.
