(CNN) — A strong earthquake struck coastal Chile about 26 miles (42 kilometers) from the port city of Valparaiso late Monday, the U.S. Geological Survey reported.

The 6.7-magnitude quake knocked out some power and phone lines in the region, but there were no immediate reports of major damage, authorities said.

The temblor was felt in the capital city, Santiago, located 69 miles from the epicenter. A CNN en Espaol 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, although the government did issue a “mandated preventive evacuation off the coast of Tangoy and Constitution.”

The same region 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.
