Clouds drape the summit of Iraya volcano at the NE end of Batan Island (upper right) in this NASA Landsat image (with north to the top). The morphologically youthful volcano is the northernmost active volcano in the Philippines. Iraya is the most prominent feature of the 20-km-long, dumbbell-shaped Batan island, located in the Luzon Strait between Luzon and Taiwan. The Pliocene to early Pleistocene Mount Mataram volcano forms the SW end of Batan Island. The tip of Sabtang Island is at the lower left.

Forested Iraya volcano rises above the airport on Batan Island. The morphologically youthful volcano is the northernmost active volcano in the Philippines. The 1009-m-high Quaternary stratovolcano has a 1.5-km-wide summit crater, which is largely filled by a younger cone that forms the summit of the volcano. A pyroclastic-flow deposit was radiocarbon dated at about 1500 years ago, and a historical eruption was reported in 1454 CE.
