They sit in the South Atlantic Ocean. This chain is in the sub-Antarctic region. It is southeast of South Georgia. It is also northeast from the Antarctic Peninsula. The group has 11 main islands. These islands form a long arc from north to south.

The islands are divided into four groups. The north has the Traversay and Candlemas Islands. The middle has the Central Islands. The south has Southern Thule. Montagu is the largest island. Mount Belinda on Montagu is the highest point. Mount Michael on Saunders Island is also very special. It has a lava lake. A lava lake is a pool of hot, liquid rock. Only eight volcanoes in the world have one.

No people live on these islands. They are very remote. The islands can have violent earthquakes. Nine large earthquakes happened there in the last century. One big quake happened in August 2021. No one died from these shakes because no one lives there.
