The forested volcano of Mahagnao (also known as Kasiboi) in central Leyte Island lies beneath cloud banks at the upper right. The volcano rises to the NE of Ormoc Bay (bottom left) and the city of Ormoc at the head of the bay. The andesitic volcano contains a steep-walled forested summit crater open to the south. Crater lakes and thermal areas with fumaroles and mud pots occur on the flanks of the volcano. An eruption was reported from Mahagnao in 1895, but no details are available.
