When they blow off you can spot them with a telescope.
you can only find volcanoes on the inner planets: that are Venus, mercury and mars
No, not all jovian planets have active volcanoes. For example, Jupiter and Saturn do not have active volcanoes. However, some of the moons that orbit these planets, such as Io (a moon of Jupiter), do have active volcanoes.
