A strong earthquake with a revised magnitude of 7.5 struck the Drake Passage on Thursday, shaking the remote region between South America and Antarctica but posing no widespread tsunami threat, according to the Pacific Tsunami Warning Center.
Initially reported as an 8.0 magnitude event, the US Geological Survey (USGS) later downgraded the quake and confirmed it occurred at a shallow depth of 11 kilometers (7 miles). The epicenter was located over 700 kilometers (435 miles) southeast of Ushuaia, Argentina — the southernmost city in the country with a population of approximately 57,000.
