A strong quake hit western Argentina, shaking buildings as far away as Santiago, the capital of neighbouring Chile, though there were no preliminary reports of damage to people, infrastructure or basic services. Chile's navy ruled out a tsunami after the quake, which the U.S. Geological Survey said was a magnitude 6.4. Although a magnitude 6.4 is considered a strong earthquake capable of causing severe damage, it was fairly deep — 115.71 kilometres below the Earth's surface, which would have lessened its effects. It is one of the most earthquake-prone countries in the world, and in 1960 was hit by a 9.5 magnitude quake, the strongest in recorded history. In recent years, the biggest quake to hit Chile was an 8.8 magnitude tremor that struck the central-southern region in 2010, triggering a tsunami and killing more than 500 people.
