Manam , called Manam Motu by locals , is an inhabited island in the Bismarck Sea and separated from the north coast of New Guinea by the Stephan Strait .

geography

The distance to Hansa Point is 13.3 km. The island with its almost circular plan has a diameter of a good 10 km. It owes its existence to the activity of the Manam Volcano , one of the most active volcanoes in Papua New Guinea. Before the last volcanic eruption, the island could be reached by boat from the coastal town of Bogia, 18 km further south .

In 2005 Manam had a population of 10,677 in 1,880 families or 16 villages. The largest villages on the island are Baliau (north), Dugulaba (also Dukulawa, in the southeast) and Kuluguma (west).

administration

Manam is part of the Bogia District in the north of Madang Province . Together with the small island Boisa (Aris) located four kilometers to the northwest, Manam forms the Iabu Rural LLG (Local Level Government) Area , with the wards (statistical counting districts) named after villages (clockwise, starting in the north, population 2000 census):

geology

Manam is a basaltic-andesitic stratovolcano that, despite its extremely symmetrical lower mountain flanks, divides the island into four valleys. These are also known as "avalanche valleys", as pyroclastic currents can arise in these during eruptions . Because of this, these valleys are highly endangered areas during eruptions that are evacuated first of all. The first reports of a volcanic eruption of Manam date from 1616.

Eruptions and dangers

Thirteen residents were killed in an eruption on December 3, 1996 when pyroclastic currents reached the settlement of Budua (Bodua) on the south coast.

In November 2004, over 9,000 islanders were evacuated due to a major volcanic eruption. The outbreak began on October 24, but was not initially seen as a major threat. This changed when the wind changed direction and ash rained on populated areas. Five people were killed.
