|Elevation||−24 metres (−79 ft)|
|Mountain type||Submarine volcano|
The volcano is located 5 kilometres (3.1 mi) off Ibugos Island, at the southernmost end 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 metres (79 ft) of the sea surface, 3.2 kilometres (2.0 mi) due west of Dequey Volcano.
It is one of the active volcanoes in the Philippines.
Submarine eruptions reported in 1773, 1850, and 1854 are likely to have originated from this volcano. There have been no further reports since 1854.
The Global Volcanism Program lists it as an unnamed historically active volcano. Philippine Institute of Volcanology and Seismology (PHIVOLCS) lists  23 active volcanoes in the Philippines, but has not included this unnamed volcano, or any volcanic activity at this geographical location.
Volcanoes of the Philippines are all part of the Pacific ring of fire.
