Text and Images from Slide

15.4 When do mass movements occur?

Image before earthquake in Peru 1970.

Fig 15.22

Image after the earthquake debris avalanches and a mixture of rock and ice bury the town.

Peru, 1970: earthquakes trigger debris avalanches around Nevado Huascaran. The mixture of regolith, rock, and ice buried the town of Yungay, killing 18,000.
