Numerous rockfalls were detected in the Las Cuevas valley, Argentina,
after the 27 February 2010 earthquake in Chile. Live rockfalls were
observed during aftershocks of 11 March 2010. Many rockfall source
areas coincide with known thrust fault and some areas presented a
rockfall activity even after the tremors. Some rockfalls crossed
the National Road 7 but no damages to houses or vehicles were reported.
This study illustrates how the 27 February 2010 earthquake impacted
on unstable slopes in a valley far from the earthquakes epicentre.
It is an interesting addition to previous studies on landslides caused
by earthquakes because of the high magnitude of the event and of
its aftershocks.
