Aoba, Ambae Island, Vanuatu
Location: 15.4S, 167.8E
Elevation: 4,907 feet (1,496 m)
Aoba is a shield volcano with a large shallow crater, called Manaro, which
contains one or more lakes. Manaro contains gas vents that can be heard
some distance away, hot springs, and solfataras. Most of Aoba is made of
tephra but a few thin basaltic lava flows have been noted.
In 1995, there was a strong gas discharge event with large amplitude tremor
at Aoba. The Michigan Tech Volcanoes homepage describes the volcanic unrest at Aoba in 1995.
