People from villages near Pago reported a a single booming noise and viewed white vapor emissions on 27 August. Increased seismicity was observed during 27-28 August. Lava was thrown out of the second crater on 28 August and steam could be seen. [details]
Pago volcanPago volcano is located in the Cape Hoskins area of New Britain, Papua New Guinea. It belongs to the larger complex of Witori volcano and represents the post-caldera cone of the latter.
Pago is probably only 350 years old.
The typical historical activity at Pago volcano were strombolian to vulcanian explosions, sometimes accompanied by slow lava flows. A series of 10 dacitic lava flows from Pago cover much of the caldera floor.
Introduction:The 250 m high and 300 m wide cone of Pago volcano reaches about the same height as the caldera rim. Pago and the 5.5 x 7.5 km caldera form a large volcanic complex, called the Witori volcano. The caldera formed probably around 3300 years ago. Witori volcano has long been recognized as active and is considered as a potential volcanic hazard.
The Buru caldera cuts the SW flank of Witori volcano. The gently sloping outer flanks of Witori volcano consist primarily of dacitic pyroclastic-flow and airfall deposits produced during a series of five major explosive eruptions from about 5600 to 1200 years ago, many of which may have been associated with caldera formation.
Pago volcano erupted in August 2007. Residents heard "a single booming noise" on 27 August. On 28 August incandescent lava was ejected from one of the upper vents.

unconfirmed 2004 eruption

2002-03 explosive & effusive eruption
An eruption began at Pago volcano on 3 August 2002, after several months of reports of vegetation dying off at the summit. The eruption opened several vents on a new fissure extending NW from the summit. In the first days, large explosions produced tall ash plumes up to 10 km high, and caused severe problems due to ash fall.
In the following effusive phase, several lava flows were erupted. The eruption declined, but went on for more than a year until it ended sometime in October 2003. ...plus
