The volcano is 5 kilometers (3.1 mi) off Ivuhos Island, at the southernmost end of the Batanes Islands, in the province of Batanes, in the Cagayan Valley Region, in the Philippines, within the Luzon Strait between Luzon and Taiwan.

The volcano is a submarine volcano rising to within 24 meters (79 ft) of the sea surface, 3.2 kilometers (2.0 mi) due west of Dequey Island.

The Global Volcanism Program lists it as an unnamed historically active volcano.

[1] Philippine Institute of Volcanology and Seismology (PHIVOLCS) lists [2] 23 active volcanoes in the Philippines, but has not included this unnamed volcano, or any volcanic activity at this geographical location.

The volcanoes of the Philippines are all part of the Pacific ring of fire.
