Zhupanovsky (Kamchatka, Russia): KVERT reported that the eruption at Zhupanovsky had likely finished in mid-October; satellite images last detected an explosion on 11 October and a thermal anomaly on 12 October.
Volcanologists conducting an overflight on 17 October observed only gas-and-steam activity from the active crater. The Aviation Color Code was lowered to Yellow.

Ontake-san (Honshu): White plumes rose 100-300 m above the crater rim and drifted NE and SE during 29-30 October and 4 November. The Alert Level remained at 3 (on a scale of 1-5).

Mayon (Luzon Island): PHIVOLCS reported that during 28 October-4 November white plumes rose from Mayon’s crater and drifted SW, WSW, WNW, and NW, sometimes down the flanks. Weak incandescence from the crater was noted at night on 28 October.
A few volcanic earthquakes and rockfall signals were recorded during 29-31 October and 4 November. A 4 November report noted that ground deformation had been detected since the beginning of 2014.
Tilt data from the network on the NW flank indicated continuing inflation since August, subsequent to a period of inflation in June and July. The inflation events were thought to correspond to a magma body, approximately 107 cubic meters, slowly intruding at depth. Precise leveling measurements also indicated sustained inflation. The Alert Level remained at 3 (on a 0-5 scale).
