Santiago, Chile: Sending shockwaves, a strong 6.0-magnitude earthquake shook Chile on Monday.
Though casualties have not been reported, buildings rattled in the capital where a big anti-government demonstration has been under way.
The quake struck at 6:53 pm (2153 GMT) with its epicenter near the northern town of Illapel, the US Geological Survey said. A strong and prolonged shaking was felt in the capital.
Chile's National Seismological Center measured the quake at magnitude 6.1, revising down an earlier estimate of 6.3.
"There have been no reports of damage to people, disruption of basic services or infrastructure," the National Emergency Office said.
The Army Hydrographic and Oceanographic Service said the quake was unlikely to cause a tsunami on Chile's Pacific coast.
Chile is one of the world's most earthquake-prone countries.
