Volcanic eruptions are an area effect found around the low-level Wilderness Chaos Temple, the Blighted Volcano, and the Fossil Island Volcano. The lava in these locations shoots out balls of fire at random intervals, which will first shoot up to a certain height, and then crash down onto game tiles within 8 tiles of the original source of the fire ball. The shaking of the screen at the Blighted Volcano is independent of the fireballs, and doesn't indicate when a fireball will launch.

The fire balls in these eruptions can only land on walkable tiles, but this may include tiles that are inaccessible (e.g. walkable tiles on an inaccessible island in the lava). They will deal one hitpoint of damage to all players standing in a 3x3 square, centred around the impact location of the fire ball. Due to being area-of-effect damage, this is typeless damage, and therefore cannot by avoided by using protection prayers. The damage is also lethal.

Due to each fire ball source only shooting one fire ball per time interval, some areas around these volcanic locations are more heavily bombarded than others. The closer players are to multiple sources, the higher the chance of standing on a tile that gets targeted.

The fire ball effect of volcanic eruptions can be seen in three areas. Each of these locations has a different amount of fire ball sources, which is also listed in the table.
