Manam volcano (Papua New Guinea) activity update: strong intermittent explosive activity, occasional pyroclastic flowsThursday Aug 02, 2012 09:21 AM | BY: T
RVO reported that activity at Manam increased slightly during 15-31 July, except from 18 to 20 July when there were fewer ash emissions. During most of the reporting period, when visibility was clear, gray-to-sometimes-black ash plumes were observed rising 300-700 m above the crater from two vents and drifting NW. Rumbling was often heard on the island; rumbling on 25 July was heard on the mainland 25 km SW. Bright glow visible at night was attributed to ejected incandescent tephra. Sub-Plinian activity occurred on most nights during 21-31 July. Small lava flows descended the SW flank. Four pyroclastic flows traveled down the SE flank on 30 July at 0638, 0640, during 1200-1300, and at 1428. The first event was the largest, and generated an ash plume that rose 1.8 km above the crater and drifted NW. Emissions from Main Crater were milder and mostly characterized by white and bluish plumes, and occasional gray ash plumes. (Smithsonian / USGS Weekly Volcanic Activity Report)
