A major earthquake of magnitude 7.1 struck off the west coast of Chile on Monday, rocking the capital Santiago and briefly causing alarm along the Pacific Coast but not producing any serious damage.
The quake was centered 22 miles (35 km) west of the coastal city of Valparaiso at a shallow depth of 6.2 miles (10 km) below the sea, and about 85 miles (137 km) from Santiago, the U.S. Geological Survey said.
"It was short but very powerful," said Paloma Salamo, a 26-year-old nurse, who was in a clinic in Viña del Mar, just north of Valparaiso, when the quake struck.
People ran out of the facility carrying children and some headed for the hills when the tsunami alarm sounded, she said, but calm was soon restored.
There were no reports of structural damage in Valparaiso, but cellphone networks were down in some places, a spokesman with the local government in Valparaiso said.
"We have no reports of victims or significant damage. There have been some landslides in some places, without major complications," said Interior Minister Mario Fernandez.
Several aftershocks including two of magnitudes 5.0 and 5.4 were recorded in the same spot and could be felt in Santiago, part of a cluster of tremors from that area in recent days.
