Hargy VulkanHargy volcano (also referred to as Eve, Galloseulo, Ibi, Richthofen, Gallosculo) is a little-known volcano in eastern New Britain, but it has one of New Britains's largest calderas, which measures 12 x 10 km.
There are no known historic eruptions and the last activity has been dated to ca. 1000 years ago, but weak fumarolic activity was observed from the SE side of the western summit crater during an overflight in early September 1990.
Numerous small eruptions have taken place from a vent inside the caldera (at the Galloseulo lava cone) over the past 7000 years.
Beschreibung:The Hargy caldera contains an inner caldera with a steep west-facing wall. The latest caldera-forming eruption of Hargy volcano took place about 11,000 years ago.
The caldera floor is 150 m above sea level and contains a lake on the SW side, which drains through a gully in the northern rim.
A post caldera dacitic Galloseulo lava cone rises above and partially overtops the western rim of the caldera. A double crater occupies a larger 700-m-wide crater.
