Iraya rises above the airport on Batan Island and is the northernmost active volcano in the Philippines. It has a 1.5-km-wide summit crater, which is largely filled by a younger cone that forms the summit. A pyroclastic flow deposit was radiocarbon dated at about 1,500 years ago and a historical eruption was reported in 1454 CE.
