Sassagara volcanoSessagara volcano is a small volcanic field in eastern New Guinea. It is ocated 8 km inland from the coastal village of Uiaku near the mouth of the Uiaka River, south of Collingwood Bay.
The lavas of the field are alkalic andesitic. Their precise age is unknown, but 2 of the cones north of the Goropu Mountains have fresh-looking preserved summit craters and erupted probably less than 10,000 years ago. The other cones are probably older.
