MEXICO CITY, Nov. 20 (Xinhua) -- A 6.4-magnitude earthquake occurred in west-central Argentina at 5:57 p.m. local time (20:57 GMT) Sunday, the U.S. Geological Service (USGS) reported.
With an epicenter some 10 km south-southwest of Zonda, Argentina, the quake occurred at a depth of nearly 116 km, which could explain the lack of reaction out of Argentina, despite the relative strength of the temblor.
While Argentine news services ignored the quake, media in neighboring Chile reported the seismic waves were felt in the central part of that country.
"A strong quake with an epicenter in Argentina was felt Sunday afternoon in the country's central zone," the daily El Mercurio online reported.
The National Office of Emergency of Chile's Interior Ministry (ONEMI) said via Twitter that initial reports indicated there were no injuries or damage to buildings.
