德國地學研究中心GFZ：南桑威奇羣島地區發生6.6級地震。

The Ministry of Natural Resources' Tsunami Warning Center said a preliminary magnitude-6.6 earthquake struck at 18:26 BJT on July 11, 2026, in the South Sandwich Islands region (55.43°S, 29.10°W) in the South Atlantic, at a focal depth of 15 km. The centre judged the quake could generate a local tsunami near the epicentre but, because the epicentre lies outside the Pacific, it does not pose a threat to China's coast. Exact parameters will be confirmed by the China Earthquake Networks Center (CENC); the tsunami centre said it will continue to monitor and issue updates.
