Chile's emergency office predicts that waves could hit the coast by 11 PM. People living in low-lying areas along the shore have ordered to evacuate.
Chile was hit by a magnitute-8.8 earthquake in 2010 that destroyed over 200,000 homes and killed more than 500 people. Situated near the Nazca tectonic plate, Chile also saw the strongest quake ever recorded. With a magnitude of 9.5, that incident occurred in 1960 and killed over 5,000.
