PVMBG reported that during 1 November 2015-4 January 2016 white and gray plumes from Semeru rose as high as 500 m above the crater and drifted E, S, and W; inclement weather sometimes prevented observations. In November nine incandescent avalanches traveled 100-500 m down the flanks.
During December 2015-4 January 2016 incandescent material was occasionally ejected above the crater. Seismicity was dominated by signals indicating avalanches and emissions. The Alert Level remained at 2 (on a scale from 1-4); visitors and residents were warned to avoid the SE flank within 4 km of the crater.
