The 1965 La Ligua earthquake (also known as the Aconcagua earthquake) struck near La Ligua in Aconcagua Province, Chile, about 140 km (87 mi) from the capital Santiago on Sunday, March 28 at 12:33 local time. The moment magnitude (Mw) 7.4–7.6 earthquake killed 400–500 people and inflicted US$1 billion (adjusted for inflation) in damage. Many deaths were from El Cobre, a mining location that was wiped out after a series of dam failures caused by the earthquake spilled mineral waste onto the area, burying hundreds of residents. The shock was felt throughout the country and along the Atlantic coast of Argentina.
