The earthquake struck in the Drake Passage, between the southern tip of South America and Antarctica. The tremor was recorded on August 22, 2025, at 2:16 a.m. UTC. Some systems initially estimated its magnitude at 8.0, but the United States Geological Survey later revised it to 7.5.
The earthquake’s focus was located at a depth of approximately ten kilometers. Due to the possibility of movement on the ocean floor, a tsunami warning was issued for certain parts of Antarctica. Authorities in Chile and Argentina closely monitored the situation, although the epicenter was far from populated areas.
The Drake Passage is known for its powerful currents, severe storms, and high waves. It connects the southern parts of the Atlantic and Pacific oceans, while the nearest major settlements are located hundreds of kilometers away. The remoteness of the region made it difficult to quickly assess the possible consequences.
After analyzing data from ocean monitoring systems, experts reported that no major tsunami had formed. The warning was lifted, and no evacuations were ordered in Chile or Argentina. There were also no reports of deaths, injuries, or serious destruction.
Despite the fortunate outcome, the incident showed how quickly a powerful underwater earthquake can place several countries on high alert. During the first few minutes, the exact magnitude is often still unknown, so emergency services prepare for the most dangerous scenario until monitoring systems rule out the threat.
Seismologists continued monitoring the region because of the possibility of aftershocks. The main recommendation for people living near the coast remains unchanged: follow official warnings and stay away from the shoreline whenever a tsunami threat is announced.
