The quake, which struck at 10:40 a.m. ET, was centered 780 miles north of Santiago, or 25 miles east-southeast of Tocopilla, the USGS said.
The USGS said it occurred 38 miles beneath the surface.
"It was horribly strong. It was very long and there was a lot of underground noise," said Andrea Riveros, a spokeswoman for the Park Hotel in Calama, about 60 miles east-southeast of the epicenter.
She said the quake knocked out power to the hotel, but caused no damage.
Carmen Fernandez, head of the government's Emergency Bureau, said the quake was felt across nearly 1,300 miles, from Chile's northern border with Peru to the capital.
There were no immediate reports of damage or injury from the region
