Mount Terror is the second largest of the three volcanoes that make up Ross Island, and is surpassed by Mount Erebus, about 30 km to the west . The volcanic cone, which consists mainly of loose volcanic material with a basaltic composition, has numerous secondary craters on its flanks. The rocks of the summit region have not yet been explored; Age dating of samples from deeper regions resulted in an age between 1.75 and 0.82 million years. A recent volcanic activity could not be detected at Mount Terror.

The volcano was named in 1841 by James Clark Ross after the HMS Terror , the second ship in his expeditionary fleet. Its flagship gave its name to Mount Erebus.

The first ascent of the 3262 m high mountain took place in 1959 by a New Zealand group.
