a small cone-shaped volcano that has been erupting almost non-stop for centuries possibly over 800 years spitting glowing lava bombs, ash plumes, and molten rock into the night sky like a never-ending fireworks show. Welcome to Mount Yasur, the legendary “Lighthouse of the Pacific” on Tanna Island, Vanuatu.
This isn’t a dormant giant waiting for a big bang. Mount Yasur is one of the planet’s most reliably active volcanoes, delivering persistent Strombolian eruptions (mild to moderate explosions hurling lava fountains) day after day, year after year all while being surprisingly accessible to adventurous visitors.
Here are breathtaking night views of Mount Yasur’s eternal glow and explosive eruptions lighting up the darkness:
Why Is Mount Yasur Called the “Eternal” Volcano?
Documented eruptions date back to at least 1774, when Captain James Cook first spotted its glowing ash plumes from the sea the fiery light guiding him to Tanna Island. But geological evidence suggests this Strombolian-style activity has continued for hundreds of years, possibly since around 1270 AD or earlier.
- Nearly continuous activity: Frequent explosions from multiple vents in its 400-meter-wide summit crater.
- Strombolian & Vulcanian bursts: Lava bombs soar up to hundreds of meters, with occasional ash clouds and gas plumes.
- Persistent glow: A near-constant display of molten lava and fire, earning its nickname as the “Lighthouse of the Pacific.”
Even in 2026, Yasur remains active with regular thermal anomalies, explosions, and monitoring by the Vanuatu Meteorology and Geo-Hazards Department.
A Small but Mighty Volcano
At just 361 meters (1,184 feet) tall, Mount Yasur is compact yet powerful. Its largely unvegetated pyroclastic cone sits within the Yenkahe caldera, part of the Pacific Ring of Fire where tectonic plates collide.
What makes it extra special? You can get remarkably close (safely guided, of course) standing on the crater rim to feel the ground rumble and watch lava fountains explode right in front of you!

The Ultimate Adventure: Visiting Mount Yasur
Mount Yasur is one of the world’s most tourist-friendly active volcanoes. Guided tours take you by 4×4 across ash plains to viewing spots where you can witness eruptions up close especially magical at sunset or night.
Thrill-seekers often describe it as once-in-a-lifetime: the roar of explosions, the heat on your face, and glowing lava arcing through the sky.
Tourists safely watching the fiery spectacle from the crater rim area:
Safety note: Activity levels are monitored (Alert Level system 0–5). Always follow guides and stay outside restricted zones lava bombs can travel far!
Why Mount Yasur Captivates the World
- Geological wonder → One of the longest continuously erupting volcanoes on Earth.
- Cultural significance → Sacred to locals, including the John Frum cargo cult who believe a spirit resides within.
- Bucket-list destination → Recognized by the International Union of Geological Sciences as a global geological heritage site.
