| We're heading to Fumarole Beach in the north of the island, home to one of Ischia's hottest thermal springs. |
| These areas are known as hydrothermal regions, fumarole fields, or solfatara fields. |
| This fumarole is only a bomb or rounded mass of enormous size, four or five metres in diameter. |
| The most typical signs of an impending eruption are shallow earthquakes, ground deformation, increased volcanic gas release, increased fumarole vigour and temperatures, and minor landslides and rockfalls. |
| He survived only by lying next to a thermal fumarole, scalding one side of himself while freezing the other. |
| A fairly constant fumarole can be seen emanating from the crater. |
