A man checks his cell phone after receiving a message from the national emergency office, ONEMI, urging people to abandon coastal areas after a quake at the Chilean Antarctic territory, in Vina del Mar, Chile, January 23, 2021.
Authorities in Chile have said they regretted spreading panic with a mistaken tsunami warning calling for people to get out of coastal areas following an earthquake in Antarctica.
The interior ministry said on Twitter that a tremor of magnitude 7.1 struck at 8.36 p.m. 216 km northeast of the O'Higgins Chilean scientific base and called for the coastal regions of Antarctica to be evacuated because of a tsunami risk.
The ministry also sent a message to cellphones around the country urging people to abandon coastal areas, though the ministry later said it was sent in error.
❗Atención. Reiteramos que no se ha declarado evacuación para el borde costero a nivel nacional, sólo para zona de playa del territorio antártico. https://t.co/xtT2KWaf8E

"We want to provide peace of mind to the population, tell them that it is not necessary to evacuate the entire national territory, only the Antarctic base," Miguel Ortiz of the ministry's National Emergency Office (ONEMI) told a news conference.
He said the agency regretted the inconvenience caused by its messages, which he blamed on a technical error.
A cell phone is seen with a tsunami warning message sent by mistake by the national emergency office, ONEMI, that reads: "State of caution. ONEMI establishes to abandon the beach area. Keep distance due to Covid-19", after a quake at the Chilean Antarctic territory, in Vina del Mar, Chile January 23, 2021.

The tsunami warning for Antarctica was later lifted.
People in coastal cities including La Serena, to the north of Santiago, and Valparaiso, started to leave areas close to the coast after the warning until reports started appearing that it was a false alarm.
But as Chileans were reacting to the warning, a second tremor, of magnitude 5.6, struck the Chile-Argentina border region, at 9.07 pm, the GFZ German Research Center for Geosciences said, at a depth of 133 km and 30km east of Santiago.
No damage was reported from either quake.
The second one was close to Codelco's Andina and Teniente copper mines and Anglo American PLC's Los Bronces.
The Chilean mining regulator Sernageomin said that workers, mining operations and facilities had reported no problems after the quake.
Sernageomin said that following the first quake, 80 people were evacuated from Chile's main base in the Antarctic, the Presidente Eduardo Frei Montalva Base on Fildes Peninsula west of King George Island, and 55 more from three other bases, along with five foreign bases.
The army said no damage was reported at the Antarctic base.
