- ‘They may be caused by a complex system of faults or by changes in the volcano's magma plumbing system.’
- ‘Some of the salt in the oceans comes from undersea volcanoes and hydrothermal vents.’

- ‘It looked a pleasant enough place from the ship even if, according to the guide books, it was built in the crater of an extinct volcano.’

- ‘They fled their homes with a few personal belongings, escaping the acrid sulphuric fumes and lava of an erupting volcano.’
- ‘Visually, the city keeps you enthralled, with its setting atop a series of extinct volcanoes and rocky crags.’
