Maninjau caldera is the largest silicic volcanic center in the Padang area of central Sumatra. The elongated caldera, filled by a lake, was formed during three Pleistocene eruptive episodes. K-Ar dating on the andesites and tuffs surrounding the caldera yielded ages of 0.83 +/- 0.42 Ma for older pre-caldera andesites (Barber et al., 2005). The youngest rhyolitic ashflow deposit was dated at about 0.28 +/- 0.12 million years (Leo et al., 1980; Barber et al., 2005).
