( CNN ) -- A strong earthquake struck coastal Chile near the port city of Valparaiso late Monday , causing mudslides and some minor damage , the U.S. Geological Survey reported . The 6.7-magnitude quake knocked out some power and phone lines in the region , authorities said . The temblor was felt in the capital city , Santiago , located 69 miles from the epicenter . A CNN en EspaÃ±ol anchor held onto his desk as the quake rattled the studio during a newscast in Huechurba , a suburb of the capital . `` We could feel the ground shaking , '' said journalist Richard Madan . `` It felt like we were standing on a subway track but multiply that by about 200 . '' Madan , of CNN 's Canadian affiliate CTV , is in Santiago as part of the traveling press for Canadian Prime Minister Stephen Harper 's visit there . Both he and the Canadian delegation were okay , Madan said . No tsunami warning was issued , according to Chile 's Hydrographic and Oceanographic Service , and a preventive evacuation for the area has been lifted . A 72-year-old man died of a heart attack during the evacuation , according to regional Mayor Raul Celis . The same part of the country was hit with an 8.8-magnitude earthquake in February 2010 , killing hundreds of people . Chile is on the so-called `` Ring of Fire , '' an arc of volcanoes and fault lines circling the Pacific Basic that is prone to frequent earthquakes and volcanic eruptions . CNN en EspaÃ±ol 's Jose Manuel Rodriguez contributed to this report .
