KVERT reported that during 24-31 January a newer lava dome continued to extrude onto the NW part of Shiveluch's older lava dome. Lava-dome extrusion was accompanied by hot avalanches, incandescence, and fumarolic activity. A thermal anomaly was detected daily in satellite images, and ash plumes rose to altitudes of 7-8 km (23,000-26,200 ft) a.s.l. on 23 January and drifted N. Read all

INGV reported that on 28 January there was a gradual but steady decrease of activity at Etna's New Southeast Crater (NSEC). Weak and sporadic Strombolian explosions were detected at night, but then the thermal cameras recorded no anomalies associated with Strombolian activity. Lava flows from two vents at the base of the NSEC cone continued to effuse at a very low rate. Read all
