Sarik-Gajah are two pyroclastic cones right at the equator line on Sumatra island, Indonesia. The first cone is Sarik, an andesitic/ basaltic vegetated cone. The other is andesic- dacitic Gajah cone, 10 km south-west of the first one and it contains lava flow. No eruptive history ever recorded from this volcanic complex.
