21. This volcanic process has created Hoodoo's structure and stratigraphy similar to subglacial volcanoes. 22. Lake Vostok is a subglacial lake in Antarctica, possibly the largest in the world. 23. Subglacial mounds can be mistaken for cinder cones because they may have a similar shape.24. Fissure vent Shield volcano Lava dome Cinder cone Stratovolcano Supervolcano Submarine volcano Subglacial volcano Mud volcano 25. Scientists are particularly worried about accidentally contaminating the subglacial lakes with life forms from outside. 26. As a result, the domes display the shaps and columnar joints typical of subglacial volcanoes. 27. A compilation by Siegert et al . ( 2005 ) reported 145 subglacial lakes in Antarctica. 28. During the Llanquihue glaciation Villarrica produced pyroclastic flow deposits, subglacial andesite lavas and dacite dykes. 29. This meltwater mix means that subglacial eruptions often generate dangerous j�kulhlaups ( floods ) and lahars. 30. As a result, the domes display the shapes and columnar joints typical of subglacial volcanoes.
