A magnitude 6.6 earthquake was recorded Thursday night (Mar. 19th6, 2026) in the Antarctic region, approximately 998 kilometers from Ushuaia and near Base Presidente Eduardo Frei (WAP CHL-Ø5), in Chilean territory.
The quake occurred around 9:22 p.m., according to monitoring data and the bulletins from various WW Seismological monitoring sources which also reported a slightly higher preliminary magnitude and located the epicenter 173 kilometers northeast of the base.
The event triggered a rapid response from emergency agencies, which assessed potential risks along the coastline. However, the Chilean Navy’s Hydrographic and Oceanographic Service (SHOA) ruled out the possibility of a tsunami, indicating that the necessary conditions for its generation were not present.

So far, no damage has been reported, nor has it been confirmed whether the earthquake was felt at the Bases located in Antarctica.
