Mount Mariveles is an extinct volcano located in the province of Bataan in the Philippines. Mt. Mariveles and the adjacent Mount Natib comprise 80.9 percent of the total land area of the province.[2] The mountain ranges lie opposite the city of Manila across Manila Bay, providing a beautiful setting for sunsets seen from Manila.

Mount Mariveles lies at the southern end of the Zambales Mountains in the Bataan Peninsula, west of Manila Bay. Bataan province belongs to the Central Luzon or Region III of the Philippines.
Mariveles is a massive stratovolcano topped with a 4-kilometre (2.5 mi) summit caldera which drains to the north. The highest peak has an elevation of 1,388 metres (4,554 ft) asl. Mounts Pantingan, Bataan, Tarak, and Vintana are the other peaks of the volcano complex, which has a base diameter of 22 kilometres (14 mi).[1]
Mount Samat on the northern slope, and Mount Limay on the eastern slope, are major, youthful-looking flank cones of the volcano.
Mariveles is still thermally active with the following hotsprings located within the complex: Tiis Spring, Saysain Spring, and Pucot Spring.[1]
There are no recorded historical eruptions from Mariveles, with the last activity indicated by Radiocarbon dating occurring around mid-Holocene or about 2050 BCE.[3]
Rock type is predominantly biotite, hornblende, and andesite, with dacite flows and dacitic tuffs. Tectonically, Mariveles is on the Western Bataan Lineament.
The Philippine Institute of Volcanology and Seismology (PHIVOLCS), the Philippine government branch that deals with volcanology in the country, lists Mariveles as a potentially active volcano for the age of its last eruption and active thermal features.
