Valdivia
On May 22, 1960, Chile suffered the most powerful earthquake ever recorded, rating 9.5 on the moment magnitude scale, with Valdivia being the most affected city. The earthquake generated devastating tsunamis that affected Japan and Hawaii. Spanish-colonial forts around Valdivia were severely damaged, while soil subsidence destroyed buildings, deepened local rivers, and created wetlands of the Río Cruces y Chorocomayo – a new aquatic park north of the city.
