Incandescent material from the vent of Manam volcano visible from satellite (image: Sentinel 2)
jeudi, nov. 14, 2019
RVO reported that at 13:30 on 2 November a single large explosion at Manam generated a dense dark ash plume that rose 1 km above the summit and drifted northwest. A shock wave was felt at the Bogia Government station about 1 minute later. ... [details]

2007 landslide
A landslide in March 2007 killed 4 people.

2006 large eruption
A large eruption on 27 February 2006 from Manam's Southern Crater sent an eruption column to 19 km altitude and forced the evacuation of hundreds of inhabitants.

2005 major eruptions on 27-28 February
A large eruption occurred on 27 January. It formed a large eruption plume with a wide, circular umbrella ash cloud reaching a maximum of 21-24 km (60-70,000 ft) altitude.
There were 14 injured and 1 dead at Warisi village. The eruption caused widespread destruction on the island and the volcano observatory was destroyed. Ashfall was reported ~230 km W of Manam.
Another large eruption occurred around 23h00 on 28 January, generating a plume that reached 18 km altitude.

2004 large eruptions
Several large explosive eruptions occurred in late October - December 2004, producing eruption columns reaching up to ca. 15 km altitude:
24 October: 15 km altitude. Pyroclastic flows reached the sea and lava flowed 600 m down the SE valley.
31 October: 13.7 km;
10-11 November (powerful strombolian eruption): 9 km;
23-24 November: 10 km;
20 December: 15 km altitude.

5 people were killed, mostly due to inhaling ash, and 9600 people were evacuated. The ash damaged crops, water supplies, and houses.
Mild to strong strombolian-type activity from the summit crater was occurring in the intervals between the larger explosions.
The eruption had also an effusive component and generated lava flows flowing into the NE radial valley. The lava flow followed the Boakure side of the valley and covered the older flows from the 1992-1994 eruption.
