Figure 5
Epicenter locations of earthquakes triggering co-seismic rockfalls at Cerro Crestón. Green symbols indicate shaking events in the release area of rockfalls outside the Austral winter. Red and orange symbols indicate co-seismic winter rockfalls when the presence of ice “cementing” interstitial rock joints and snow on the talus likely reduces the (i) release and/or (ii) spread and reach of rockfalls. Smaller, semi-transparent symbols and corresponding years are for the period 1940–1973 for which epicenter distance control is available but information on magnitudes (M) does not systematically exist and may not be of the same quality as the one for the more recent events. LOFZ = Liquiñe-Ofqui Fault Zone.
