Geological summary
The morphologically youthful Iraya stratovolcano is the northernmost active volcano in the Philippines. It is the most prominent feature of the 20-km-long Batan Island, located in the Luzon Strait between Luzon and Taiwan. The 1.5-km-wide summit crater is largely filled by a younger cone that forms the summit. Observed late-Pleistocene and Holocene products are exclusively explosive. The youngest dated unit is a pyroclastic-flow deposit 14C dated at about 1,500 years ago (Richard et al., 1986). The Philippines Institute of Volcanology and Seismology (2004-) listed an eruption in 1454 CE of unspecified character.
