Following this seismic event, Chile’s Navy Hydrographic and Oceanographic Service issued a tsunami precaution for the Chilean Antarctic territory.

This warning came after an earlier earthquake on Wednesday evening, initially reported at a magnitude of 8.0 and later revised by the United States Geological Survey (USGS) to 7.5.

The earthquake occurred 258km (160 miles ) northwest of Base Frei, at a depth of 11km (7miles).

The tremor stuck over 700km southeast of Ushauasia, Argentina’s southernmost city, which has a population of approximately 57,000.
