A small earthquake hit just off the coast of Peru early Tuesday afternoon. Early reports estimated a magnitude of 5.6, but the USGS says the earthquake was magnitude 4.6. 

The earthquake shook buildings in Lima, Peru's capital city, but no injuries or damage have been reported, according to Reuters. A magnitude 4.6 earthquake can be felt, but rarely causes damage beyond clinking some glasses and knocking pictures askew. Earthquakes of this size happen tens of thousands of times per year.

The earthquake's center was about 22 miles northwest of Lima and 38 miles (61 kilometers) underground.

Peru is located on the "Ring of Fire," the belt of earthquakes and volcanoes surrounding the Pacific Ocean. All along its western coast, the South American plate is colliding with the Nazca plate, forcing the heavier ocean crust down into the Earth's mantle. The collision of the plates is like a slow-motion car wreck. They're colliding at only 3 inches per year, but that's enough to cause frequent earthquakes – and build the Andes Mountains.
