Diogo Island is an uninhabited volcanic island in the province of Batanes, the northernmost province in the Philippines. Also known as Dinem Island in the native language,[2] Diogo is a lone rock rising out of the sea, with steep cliffs on every side, and dangerous currents make landing there practically impossible. It is an extinct volcano which has suffered heavily from marine erosion. [3]

Geography

Diogo is a small, round island over 1,683 feet (513 m) high, about 3/4 mile (1.21 km) in diameter, lying 3 1/2 miles (5.6 km) southeastward of Itbayat Island. It is steep on the western side but has several small islets lying off the eastern side, the outermost being nearly 1/2 mile (0.80 km) distant.[4]

Geology

In 1903, Diogo Island was observed to be volcanic, discharging vapor and dark material, but another observation in 1908 believe that those are small clouds which often hang around the mountain.[3] It is listed as an inactive volcano[5] by the Philippine Institute of Volcanology and Seismology.

Previous names

In old Spanish maps, the name of the island was listed as Isla Diego or Rodonta.[6]
