A 7.1-magnitude earthquake, the strongest to hit Chile in two years, last night rocked Talca, a small city 136 miles south of Santiago, reports AP. Buildings swayed in Santiago, and people living along the coast were warned to watch for tsunamis, but there were no reports of injuries or significant damage. Fears were highest in Constitución, the resort town close to Talca that was worst hit in the devastating quake of 2010, but nothing major was reported. (More Chile stories.)
