Manam volcano (Papua New Guinea): activity summary 1-14 April 2013: strombolian activity and lava flow
Thursday Apr 25, 2013 10:05 AM | DOOR: T
RVO reported that during 1-14 April Strombolian activity was observed from Manam Southern Crater. During 1-7 April ash plumes rose above the crater. Island residents reported incandescent tephra ejections from the crater at night, and roaring and rumbling noises. Activity increased on 8 April. Strombolian activity was sustained for extended periods during 9-11 and 13-14 April. Loud roaring and rumbling noises were reported by residents in Bogia, 25-30 km SSW of Manam on the N coast of the mainland.
A few loud banging noises on 13 April rattled bush-material houses at Dugulava village on the SW side of the island. Most fragments from the Strombolian eruptions, including a small volume of lava, were channeled into SW valley. Ash plumes rose as high as 600 m above the summit crater and drifted NW. White vapor plumes rose from Main Crater during the reporting period.
