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." [less]
