Unnamed volcano

The unnamed volcano is a submarine formation near Sabtang in the Batanes archipelago. The geological structure comes within 24 meters of the sea surface and is positioned in the Luzon Strait between several islands.

The volcano has a recorded history of three documented submarine eruptions occurring in 1773, 1850, and 1854. These events demonstrate ongoing volcanic activity in this part of the Philippine archipelago.

The Philippine Institute of Volcanology and Seismology maintains records of volcanic activities, though this submarine formation remains officially unnamed.

Access to this location requires specialized diving equipment and professional guidance due to its underwater location. Visitors should arrange trips through authorized research institutions or geological organizations familiar with submarine exploration.

This formation remains officially unnamed and unclassified by national authorities despite its documented eruption history. The lack of official recognition makes it a puzzle in the region's volcanic record.
