The small, but voluminous Mariveles stratovolcano is located at the southern end of the Bataan Peninsula, on the west side of Manila Bay, Luzon Island, Philippines.
Although there are no known eruptions in historic times, it is a still active stratovolcano of andesitic composition. It has a 4-km-wide caldera open to the south. Mount Slamet on the north and Mount Limay on the east are 2 large, young flank cones.
