Global Volcanism Program | Image GVP-11148

The large 2-km-wide, 600-m-deep crater that extends down the SSW flank of Banahaw contained a crater lake until 1730, when it drained, producing lahars.  The smaller San Cristóbal and Banáhao de Lucban have formed on the W and E flanks, respectively. Andesite-to-dacite lava domes formed on the flanks of Banahaw and San Cristobal.
