Chilean authorities said they regretted the panic caused by the wrong tsunami, which warned people to leave coastal areas after the earthquake in Antarctica.
The Ministry of the Interior said on Twitter that at 8.3 pm local time, a magnitude 7.1 earthquake occurred 216 kilometers northeast of the O’Higgins Chile Science Base, and called for the evacuation of the Antarctic coastal area because of the risk of a tsunami.
The ministry also sent a message to mobile phones across the country urging people to abandon the coastal areas, although the ministry later stated that it was sent in error.

He said the agency regrets the inconvenience caused by its information, and he blames it on technical errors.
The tsunami warning for Antarctica was later lifted.
After the warning was issued, people in coastal cities, including La Serena and Valparaiso in the north of Santiago, began to leave the coastal areas until reports said it was a false alarm.
However, when the Chileans responded to the warning, the GFZ German Geoscience Research Center said that the second magnitude of 5.6 hit the Chile-Argentine border area at a depth of 133 kilometers and 30 kilometers east of Santiago.
No damage was reported in the two earthquakes.
The second is near the Andina and Teniente copper mines of Codelco and Los Bronces of Anglo American PLC.
Chile’s mining regulator Sernageomin said that after the earthquake, there were no problems with workers, mining operations and facilities.
Sernageomin said that after the earthquake, 80 people were evacuated from the main base in Chile’s Antarctic, President Eduardo Frey Montalva on the Fildes Peninsula west of King George Island, and 55 people were evacuated from three other bases and five. Two foreign bases were evacuated.
The Army said there were no reports of losses at the Antarctic base.
Chile is one of the most earthquake-prone countries in the world. Just off the coast, the Nazca tectonic plate fell below the South American plate, turning the towering Andes mountains into higher elevations.
In 2017, 1 million people were evacuated from their homes after the 8.3 magnitude earthquake.
The strongest earthquake on record occurred in Chile in 1960, when a magnitude 9.5 earthquake killed more than 5,000 people.
