A strong earthquake (sismo) with a preliminary magnitude of 6.4 has struck near San Juan in western Argentina, with tremors being felt as far away as Chile's capital Santiago, seismologists and residents say.

The earthquake, which struck at 5:57 p.m. local time on Sunday, was centered about 75 kilometers west of San Juan, or 253 kilometers northeast of Santiago. It struck at a depth of about 115 kilometers, making it a deep earthquake.

Chile's seismological agency put the preliminary magnitude of the earthquake at 6.3, while the U.S. Geological Survey (USGS) put the magnitude at 6.4. Shaking was felt across parts of Argentina and Chile, including cities such as San Juan, Mendoza, San Rafael, San Felipe, and Santiago.

There was no immediate word about damage or casualties, but authorities say there is no threat of a tsunami because the earthquake was centered on land. We're working to gather additional information.
