It is located between 116° 40', and 126° 34' E. longitude and 4° 40' and 21° 10' N. latitude and borders the Philippine Sea on the east, the South China Sea on the west, and the Celebes Sea on the south.found in the Philippines.Most of the mountainous islands are covered in tropical rainforest and volcanic in origin. Here are the list of volcanoes found in the island of Philippines

Complex Volcano

          A complex volcano, also called a compound volcano, is a volcano with more than one feature. They form because changes of their eruptive characteristics or the location of multiple vents in an area. Stratovolcanoes may form complex volcanoes, because they may overlap another from explosive eruptions, lava flows, pyroclastic flows and by repeated eruptions, to make multiple summits and vents.

      Stratovolcanoes could also form a large caldera that gets filled in by multiple small cinder cones, lava domes and craters may also develop on the caldera's rim.  Although a comparatively unusual type of volcano, they are widespread in the world and in geologic history. Metamorphosed ash flow tuffs are widespread in the Precambrian rocks of northern New Mexico, which describes that caldera complexes have been important for much of the Earth's history. Yellowstone National Park is on three partly covered caldera complexes. The Long Valley Caldera in eastern California is also a complex volcano; the San Juan Mountains in southwestern Colorado are formed on a group of Tertiary-age caldera complexes, and most of the Mesozoic and Tertiary rock of Nevada, Idaho, and eastern California are also caldera complexes and their erupted ash flow tuffs. The Bennett Lake Caldera in British Columbia and the Yukon Territory is another example of a Tertiary-age caldera complex
