On Tanna island, Mount Yasur rises 300 meters into the sky.
Yasur is an active volcano, and it erupts almost every day, sometimes several times a day .
For centuries, both island locals and visitors have also climbed this mountain to visit the top.
Recently, people have also started climbing Yasur to surf the volcano .
In some ways, volcano surfing is like surfing in the sea, but in other way it's very different.
A volcano surfer's goal is to escape the erupting volcano without getting hit by flying rocks!
It's fast,fun, and dangerous the perfect extreme sport.
