Eruptions tend to be Strombolian , tossing out bombs , or mild Vulcanian explosions.
Yasur has caused damage and been associated with a tsunami. There have been at least three deaths at Yasur in recent years. Yasur from Sulphur Bay. John Frum village is in the foreground. Some bombs are thrown as far as the forested slopes to the left Yasur's summit.
