Manam volcano (Papua New Guinea): activity summary 1-15 Oct - strong strombolian activity
Thursday Oct 18, 2012 10:05 AM | VON: T
RVO reported that Manam's Southern Crater continued to erupt during 1-15 October. Activity was low the first few days, characterized by emissions of light gray ash plumes, occasional dark gray plumes, and ejected incandescent tephra.
The intensity of ejected incandescent tephra increased on 5 October, and peaked during 9-10 October when the ejections developed into Strombolian activity. Strong explosions during the Strombolian activity produced shock waves that rattled houses on the S part of the island. Activity subsided after 10 October; erupted material fell in the SE and SE valleys. There was a corresponding increase in emissions of ash clouds that drifted NW but the volume of ash appeared insignificant. White vapor plumes rose from Main Crater during the reporting period.
Based on analyses of satellite imagery, the Darwin VAAC reported that on 15 October an ash plume rose to an altitude of 3 km (10,000 ft) a.s.l. and drifted 37 km SW.
