Magnitude 6.4 quake hits western Argentina
A magnitude 6.4 quake on Sunday hit western Argentina, northeast of Santiago, the capital of neighboring Chile, the U.S. Geological Survey said, Reuters reported.
The quake's epicenter was southwest of the Argentine town of San Juan, and about 180 miles northeast of Santiago in Chile. The tremor was initially reported as a magnitude 6.7 but was later downgraded.
Although a magnitude 6.4 is considered a strong earthquake capable of causing severe damage, it was fairly deep - 115.71 km below the Earth's surface, which would have lessened its effects.
