Manam volcano (Papua New Guinea) activity update 28 Feb - 18 March 2015: seismic unrest
Friday Mar 20, 2015 15:45 PM | BY: T
Activity at the volcano remains low, with only internal (seismic) unrest detected recently.
The latest Smithsonian / USGS Weekly Volcanic Activity Report from 11-17 March 2015 writes:
"RVO reported that activity at both Manam's Southern Crater and Main Crater was low during 1-18 March although inclement weather made crater observations difficult; no noises were reported. Seismicity had slowly and erratically increased since 28 February, peaked on 13 March and remained at that level through 15 March, and then increased again through 18 March. The seismicity was characterized by small-to-moderate, sub-continuous, and continuous volcanic tremor. Discrete low-frequency earthquakes were also recorded."

RVO reported that after a small eruption from Manam's Southern Crater during 27-28 August, activity subsided. Diffuse gray-brown ash plumes, emitted at short intervals, rose from the crater during 29-30 August, and crater incandescence was noted. Seismicity declined and was at a low level by the end of the day on 31 August. [more]
