Open AccessTree-ring correlations suggest links between moderate earthquakes and distant rockfalls in the Patagonian Cordillera
Earthquakes with magnitudes M > 7 can trigger large landslides and rockfalls at epicenter distances of up to 400 km, whereas moderate shaking (M = 5–7) is generally thought to result in abundant co-seismic mass m...
