Significant earthquake 6.0 strikes 227 km N of Copiapó, Chile

The German Research Centre for Geosciences in Potsdam (GFZ) reported a magnitude 6.0 quake in Chile only 5 minutes ago. The earthquake happened at a shallow depth of 10 km (6.2 miles). The magnitude, exact epicenter location and depth could be revised within the next few minutes as the agency updates and refines its calculations, or as other agencies issue their report.
Based on the preliminary seismic data, the quake should have been widely felt by almost everyone in the area of the epicenter. It might have caused light to moderate damage.
Towns and cities near the epicenter that are likely to be affected include Taltal (pop. 10,000) in 72 km (45 miles) distance with moderate ground shaking expected, Diego de Almagro (pop. 18,100) in 152 km (94 miles) distance, light shaking expected, Antofagasta (pop. 309,800) in 219 km (136 miles) distance, light shaking expected, Copiapó (pop. 129,300) in 227 km (141 miles) distance, light shaking expected.
This story will be updated soon by VolcanoDiscovery. If you're in the area, please send us your experience through our reporting mechanism. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.
