A 7.5-magnitude earthquake hit near Antarctica, triggering a brief tsunami warning with no reported damage.

On August 22, 2025, a 7.5-magnitude earthquake struck the Drake Passage, between South America and Antarctica. Initially reported as 8.0, the quake occurred southeast of Argentina's Ushuaia, with no immediate reports of damage or casualties. Chile issued a tsunami warning for its Antarctic territory, but this was later lifted. The remote location reduced the risk of impact to nearby populated areas.
