Mount Yasur is the Vanuatu volcano famous for frequent Strombolian eruptions and relatively easy access to its crater rim.
The volcano is on Tanna Island, in the South Pacific nation of Vanuatu. Its activity commonly consists of bursts of gas, ash, and incandescent volcanic bombs from vents within the summit crater. These regular explosions have made Yasur a major destination for visitors and a prominent feature of Tanna’s landscape.
Yasur’s accessibility does not make it harmless. Eruptions can intensify, ballistic rocks can travel beyond restricted areas, and ash and volcanic gases can affect nearby communities. Local authorities therefore regulate access according to activity levels.
Mount Yasur is sometimes confused with Vanuatu’s Manaro volcano, which is on Ambae Island. Yasur is the volcano associated with Tanna and with the long-running spectacle of visible nighttime glow and explosions.
