Two tremors hit Chilean territory minutes apart on Saturday evening, according to Reuters. The first one hit Antarctica and was followed by a second close to the capital Santiago.
Chile's Interior Ministry said on Twitter that the first tremor of magnitude 7.1 struck at 8:36 p.m. local time, 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. At 9:07 p.m. local time, a tremor of magnitude 5.6 struck the Chile-Argentina border region, the GFZ German Research Center for Geosciences said, at a depth of 133 km and 30km east of Santiago.
