Some buildings are damaged, and power lines are down, in northern Chile after a powerful earthquake.
Authorities report at least 20 people injured, but no fatalities.
The quake was strong enough to send terrified people fleeing into the streets hundreds of miles from the epicenter.
It was felt strongly in Chile's capital of Santiago, nearly 800 miles to the
south, and in neighboring Peru and Bolivia.
The U.S. Geological Survey calculated the magnitude at 7.7, making it a major quake.
It was followed by several aftershocks, including two that were larger than magnitude 5.
