Interesting Facts

πŸŒ‹

Taveuni has approximately 150 volcanic cones distributed along a 40-km-long NE-SW rift zone β€” one of the densest concentrations of volcanic vents on any single Pacific island.

πŸŒ‹

At least 58 eruptions have occurred on Taveuni since the first human settlements around 950-750 BCE, making it one of the most frequently active volcanoes in the Fiji-Tonga region over that period.

πŸŒ‹

A period of voluminous eruptions between ~300 and 500 CE forced the abandonment of southern Taveuni for approximately 600 years.

πŸŒ‹

Lake Tagimoucia, a volcanic crater lake at ~830 m elevation, is the only place on Earth where Fiji's national flower (tagimoucia, Medinilla waterhousei) grows.

πŸŒ‹

Taveuni's volcanic soils are among the most fertile in the Pacific, earning it the nickname 'Garden Island.'

πŸŒ‹

The island sits near the 180th meridian β€” the International Date Line β€” and a marker at Waiyevo commemorates this geographic curiosity.

πŸŒ‹

All 34 recorded eruptions are VEI 0-2, reflecting the basaltic shield volcano's relatively gentle eruption style compared to explosive stratovolcanoes.

πŸŒ‹

Taveuni is Fiji's third-largest island, measuring approximately 40 km long and 12 km wide.

πŸŒ‹

The Rainbow Reef off Taveuni's coast is considered one of the world's premier soft-coral diving sites.

πŸŒ‹

Approximately 14,000 people live on Taveuni today, concentrated primarily along the western coast.

πŸŒ‹

The last known eruption (~1550 CE) produced a lava flow at the island's southern tip that remains clearly distinguishable from the surrounding older terrain.

πŸŒ‹

The Bouma National Heritage Park protects over 80% of Taveuni's remaining rainforest, which grows on volcanic slopes enriched by millennia of eruptions.

Frequently Asked Questions

Is Taveuni an active volcano?
Taveuni is classified as a dormant shield volcano. Its last known eruption occurred around 1550 CE β€” approximately 475 years ago. However, the geological record reveals 34 eruptions over the past 10,000 years, with at least 58 eruptions since human settlement began around 950-750 BCE. This prolific history suggests future eruptions are plausible, though not imminent. The volcano's basaltic composition means any future activity would likely produce lava flows and Strombolian-style explosive events rather than catastrophic explosions.
How many volcanic cones are on Taveuni?
Taveuni has approximately 150 volcanic cones distributed along a 40-km-long NE-SW rift zone that runs the length of the island. These include scoria cones, cinder cones, and small shield structures. This is one of the densest concentrations of volcanic vents on any single Pacific island. Most cones are in the southern two-thirds of the island, reflecting the preferential location of rift-zone eruptions.
Why is Taveuni called the Garden Island?
Taveuni is called the 'Garden Island' because its volcanic soils are among the most fertile in the Pacific, supporting extraordinarily lush tropical vegetation. The deeply weathered basaltic material is rich in nutrients, enabling dense rainforest growth, productive agriculture (copra, cocoa, tropical fruits), and the unique botanical heritage of sites like Lake Tagimoucia, where Fiji's national flower grows. The entire island's ecology is fundamentally shaped by its volcanic origins.
What is Lake Tagimoucia?
Lake Tagimoucia is a volcanic crater lake at approximately 830 m elevation in Taveuni's central highlands. It is famous as the only place on Earth where the tagimoucia flower (Medinilla waterhousei) β€” Fiji's national flower β€” grows naturally. The lake formed within one of Taveuni's many volcanic craters and is surrounded by cloud forest. It is accessible via a challenging day hike from the coast and is a significant cultural and botanical site in Fiji.
Is Taveuni safe to visit?
Yes, Taveuni is considered safe to visit. The volcano has not erupted in approximately 475 years and shows no current signs of unrest. The island is one of Fiji's premier eco-tourism destinations, offering world-class diving (Rainbow Reef), rainforest trekking (Bouma National Heritage Park), and unique volcanic landscapes. While future eruptions are theoretically possible, the current risk is very low. Standard travel precautions for tropical Pacific islands apply.
When did Taveuni last erupt?
Taveuni's last known eruption occurred around 1550 CE (estimated range 1450-1650 CE), producing a basaltic lava flow at the island's southern tip near South Cape. This was a small, effusive (VEI 0) event. Before that, the island had been intermittently active for over 10,000 years, with a particularly intense period of eruptions between 300 and 500 CE that forced human abandonment of the southern part of the island.
