Thrihnukagigur volcano is dormant – it last erupted over 4,000 years ago. There are no indications of it erupting again in the near future. The volcano’s name, mostly unpronounceable for anyone other than locals, would be directly translated as ‘Three Peaks Crater’. The most north-easterly of the three peaks is a small cinder cone, standing about 35 m/100 ft higher than its surroundings. At the top of this cone is a funnel-shaped opening, about 4×4 m/12×12 ft wide, the entrance of a huge 120 m/400 ft deep, bottle-shaped volcanic vault, measuring 50×70 m/160×220 ft at the bottom. Volcanic passages continue down to the southwest, to a total depth of about 200 m/700 ft.
