“…Almost a century earlier, in 1933, Xinmo was struck by a magnitude M s 7.5 earthquake, during which large-scale landslides destroyed villages and choked rivers, producing dammed lakes that, collapsing, produced enormous floods, killing thousands of people (Cheng et al, 2008).

However, what does not collapse during the quake is not exempt from damage.…”
