A shallow M6.3 earthquake was recorded in Drake Passage at 01:42 UTC on October 16, 2025. The event was registered at a depth of 10.0 km (6.2 miles), based on data from USGS. The coordinates for the epicenter were -61.6°S, -59.9°W.

Drake Passage is the body of water situated between the southern tip of South America and Antarctica, known for its challenging sea conditions and remoteness from large human settlements. The coordinates locate the quake in this region, far from any significant populated areas.

Given its remote offshore location in the Southern Ocean, nearby infrastructure is limited primarily to shipping routes and occasional scientific research vessels. There are no major ports or urban centers in close proximity to the epicenter.

There is no tsunami threat associated with this earthquake, based on its location and available data.

One felt report was submitted for this event. The significance index is 611 (on a scale that runs through 1 000), based on magnitude, felt reports, and estimated impact.

Drake Passage is situated along the Scotia Plate boundary, an area known for its tectonic activity due to interactions between the South American Plate, Scotia Plate, and Antarctic Plate.
