Iraya

Stratovulcano · Philippines · 1009 m

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.

Sintesi geologica

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.
