Manam volcano (Papua New Guinea): activity summary 17 June - 16 July
Thursday Jul 18, 2013 10:05 AM | DOOR: T
RVO reported that the increased activity at Manam noted during 17-18 June continued on 19 June, and then declined on 20 June. On 19 June diffuse dark gray ash plumes that rose 200 m above the summit crater were accompanied by deep, loud explosive and booming noises occurring at short intervals. Very loud explosions accompanied by shock waves were heard at much longer intervals. Observers noted ejected incandescent lava fragments at night.
Decreased activity that started on 20 June carried through 30 June, and was characterized by diffuse ash emissions at the beginning of the period changing to diffuse white vapor emissions towards the end.
Diffuse gray emissions rose from Main Crater during 19-22 June; explosion and booming noises were reported during 19-20 June. Seismicity was low. Activity at Southern Crater and Main Crater was
low during 1-14 July; both craters emitted white vapor.
