A significant magnitude 7.5 earthquake struck the Drake Passage on August 21, 2025, triggering tsunami alerts for Chile's coast. The passage, a crucial waterway between South America and Antarctica, is known for its turbulent waters and active tectonics.

The epicenter of the 7.5-magnitude earthquake was in the Drake Passage, a body of water between the southernmost tip of South America and Antarctica.

The United States Geological Survey (USGS) revised down the quake magnitude, initially reported at 8, adding that it hit at a depth of 11 km (7 miles).
