In the Balleny Islands’ archipelago, the Buckle, Sturge and Young Islands are examples of stratovolcanoes. Strong earthquakes very close to the islands are rare, but tremors of moderate strength do occur over the Pacific–Antarctic Ridge, Macquarie Triple Junction and Pacific Rim between the Balleny Islands and Macquarie Island. Other earthquakes occur near the Southeast Indian Ridge and Balleny Fracture Zone, including a magnitude 8.1 earthquake in 1998 that struck just over 700 km (430 mi) west-northwest of the Islands. The Balleny Islands lie 2000 km south of New Zealand and only a couple hundred km from the coast of Antarctica. The area is governed by the Antarctic Treaty System.

In the recent weeks, mysterious wave anomalies have been captured coming from Antarctica.
