Mount Haddington is a massive 1,630 m (5,350 ft) high shield volcano comprising much of James Ross Island in Graham Land, Antarctica. It is 60 km (37 mi) wide and has had numerous subglacial eruptions throughout its history, forming many tuyas. Some of its single eruptions were bigger in volume than a whole normal-sized volcano.[3] Old eruption shorelines are widespread on the volcano's deeply eroded flanks.

Haddington formed along the Larsen Rift dominantly during the Miocene and Pliocene epochs but more recent eruptions have produced tuff cones on its slopes. The youngest tuff cones and pyroclastic cones on the eastern slope are situated below the summit icecap and may have formed in the last few thousand years. Effusive eruptions have created large deltas composed of hyaloclastite breccia and lava flows.[2]
Mount Haddington was discovered on December 31, 1842 by the Ross expedition, a voyage of scientific exploration of the Antarctic from 1839 to 1843 led by James Clark Ross. Ross named the mountain after the Earl of Haddington, then First Lord of the Admiralty.[4]

El monte Haddington es un volcán de 1.630 metros de altura formado en el Mioceno y que se encuentra en la isla James Ross en la Antártida. Tiene 60 km de ancho y ha tenido numerosas erupciones subglaciales durante su historia, formando muchas tuyas. Algunas de sus erupciones son más voluminosas de lo que es habitual.[1] En la zona se encuentran diferentes líneas de costa fruto de antiguas erupciones y que forman profundos y erosionados flancos.[fr] Mont Haddington
Le mont Haddington est un volcan bouclier massif couvrant une grande partie de l'île James Ross, située au large de la terre de Graham, en Antarctique. Il s'élève à 1 630 m et est le point culminant de l'île. Le mont Haddington mesure environ 50 km de large et a connu de nombreuses éruptions sous-glaciaires tout au long de son histoire, formant de nombreuses tuyas[1]. Certaines de ses éruptions uniques étaient plus volumineuses que tout un volcan de taille normale.[ru] Хаддингтон (гора)
