Mount Hodson

Hodson

Stratovolkan · United Kingdom · 835 m

Glaciers descend the steep southern face of Visokoi Island from the flat-topped summit of Mount Hodson. Wordie Point (left) and Irving Point (right) lie respectively at the west and east sides of the 5.5 x 7 km wide island. The sea cliffs comprise interbedded lavas and pyroclastics. The cliffs at Wordie Point are formed by thick columnar-jointed lavas. Numerous basaltic scoria cones were constructed on the lower flanks of the island, including at Irving Point, and are thought to represent the most recent activity.

Ringkasan geologi

The largely ice-covered, 5.5 x 7 km Visokoi Island consists of a single stratovolcano, Mount Hodson, whose rounded summit lies west of the center of the island. Numerous basaltic scoria cones were constructed on the lower flanks of the island, which is part of the Traverse Islands in the northern part of the South Sandwich Island chain. The youthful morphology suggests recent volcanism (LeMasurier and Thomson, 1990). Possible eruptive activity was reported during 1830 and 1930.
