One of the most well - known active volcanoes in Vanuatu is Yasur. Located on Tanna Island, Yasur has been erupting continuously for centuries. Standing at 361 meters high, it has a 1300 - foot - wide (about 396 meters) circular crater. What makes it truly remarkable is its regular and spectacular Strombolian activity. Small to violent explosions occur regularly from one or several vents, with lava being thrown into the air. The lava usually falls straight down, rarely spraying sideways, which has earned it the title of the "world's most accessible and friendly volcano" as it seldom endangers tourists. Yasur has become a major tourist attraction, drawing thousands of visitors each year who come to witness the raw power of nature.

Another highly active volcano in Vanuatu is Ambrym. This large basaltic volcano features a 12 - km - wide caldera. It is not only one of the most active in Vanuatu but also globally. Its most active craters often contain small lava lakes. The volcanic activity on Ambrym creates a unique and awe - inspiring landscape, with the island being known as the "black island" due to the extensive ash plains covering its interior. The active volcanic cones of Benbow and Marum on Ambrym have attracted adventurous trekkers from all over the world, eager to experience the thrill of being close to such a dynamic and powerful natural phenomenon.

In total, Vanuatu has 8 volcanoes, out of which 5 are still considered active, and there is also one active submarine volcano off its coast. These volcanoes have not only shaped the geographical features of the islands but also play a significant role in the local culture and economy. The volcanic eruptions, while potentially dangerous, also bring opportunities such as tourism and the creation of fertile soil for agriculture. However, the local authorities and scientists constantly monitor these active volcanoes to ensure the safety of the inhabitants and visitors alike.
