About Koro
Koro is a pyroclastic cone(s) rising to 522 meters (1,713 feet) in Fiji's Southwestern Pacific Volcanic Regions. No historical eruptions have been recorded, though the volcano is classified based on geological evidence of past activity.
Geography & Climate
Koro is located in Fiji, within the Fiji Volcanic Arc of the broader Southwestern Pacific Volcanic Regions. Situated at 17.32° S, 179.40° E in the Southern Hemisphere, the volcano lies within a tropical climate zone. With a summit elevation of 522 meters above sea level, Koro is a moderately sized peak that remains accessible to hikers and researchers for much of the year. The volcanic landform is characterized as a composite, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
GVP Reference Summary
The 8 x 18 km Koro Island, located between Fiji's Viti Levu and Vanua Levu Islands, is part of the volcanic Lomaiviti Islands. A chain of basaltic cinder cones of late Pleistocene or possibly Holocene age extends NNE-SSW along the crest of the island (Coulson, 1976). The youngest lava flows erupted from those cones on the central plateau, where they form a flat undissected lava field. Young lava flows also reached the sea from one vent location on the W coast. In a study of peridotite xenoliths from Koro, Barrett (2021, and included references) noted that they were hosted by the most recent localized alkali basalt volcanism, and that surface volcanism had been dated between 2.6 and 1.0 Ma by K-Ar.

How high is Koro?+
Koro has a summit elevation of 522 meters (1,713 feet) above sea level. At 522 meters, it is a relatively low-elevation volcano.
What type of volcano is Koro?+
Koro is classified as a Pyroclastic cone(s). Pyroclastic cones (or cinder cones) are small, steep-sided volcanic cones built from fragments of lava blasted into the air. They are the simplest type of volcano and often form in groups.
Where is Koro located?+
Koro is located in Fiji, in the Southwestern Pacific Volcanic Regions. More specifically, it lies within the Fiji Volcanic Arc. Its exact coordinates are -17.320° latitude, 179.400° longitude.
Is it safe to visit Koro?+
