SANTIAGO — Strong aftershocks rippled through Chile on Thursday after a magnitude 8.3 earthquake that killed at least eight people and slammed powerful waves into coastal towns, forcing more than a million people from their homes. The government ordered evacuations from coastal areas after the powerful quake hit on Wednesday evening, seeking to avoid a repeat of a quake disaster in 2010 when authorities were slow to warn of a tsunami that killed hundreds. As the risk subsided, the government lifted its tsunami warning on Thursday morning. The quake and heavy waves afterward caused flooding in coastal towns, damaged buildings and knocked out power in the worst hit areas of central Chile. It shook buildings in the capital city of Santiago about 280 km (175 miles) to the south. The port of Coquimbo suffered major damage in the quake, which was the strongest in the world this year, Interior Minister Jorge Burgos told a news conference. The city was hit by waves of up to waves of up to 4.5 meters (15 feet) after the earthquake, Chile's navy said. — Reuters
