An earthquake measuring 4.5 on the Richter scale struck Antofagasta Province in northern Chile on Sunday. The US Geological Survey said in a statement that the epicenter of the quake was 92 kilometers from the city of Tocopilla in the province, and at a depth of 62.9 kilometers. So far, no reports of material damage or human losses have been reported as a result of the quake. In 2010, an 8.8-magnitude earthquake followed by a tsunami struck central and southern Chile, killing 500 people. Chile is located in an area called the Ring of Fire, which is an arc of rifts that surround the Pacific Ocean basin, and is subject to frequent earthquakes and volcanic activity.
