The 8.2-magnitude earthquake occurred about 15 km below Earth's surface. Scientists have managed to finally identify the elusive earthquake that triggered a tsunami that spread thousands of kilometres from its epicentre through the North Atlantic, Pacific, and Indian oceans in August 2021.
As Live Science explains, while scientists originally believed that the tsunami in question was caused by a 7.5-magnitude earthquake detected near the South Sandwich Islands in the South Atlantic, its epicentre was simply too deep to cause a tsunami (about 47 km below the sea floor), and that the kind of the tectonic plate rupture that caused it (400 km long) “should have caused a much larger earthquake."

Lots of earth changes happening.
Where are the Southern Sandwich Islands? South Sandwich Islands, group of actively volcanic islets in the South Atlantic Ocean, north of the Weddell Sea and 470 miles (760 km) southeast of the island of South Georgia. They extend for 190 miles (305 km), occupy 120 square miles (310 square km), and are covered with glaciers. They are east of the Falklands if you remember that war.
