On 29 October, SERNAGEOMIN received reports of an increase in activity at Chaitén characterized by several explosions that darkened the plume and caused it to rise from about 1.6 km (5,200 ft) a.s.l to about 3.1 km (10,200 ft) a.s.l. SERNAGEOMIN reported that variations in seismicity remained similar to patterns detected during the pervious weeks. A gas plume was continually emitted to an altitude of 3.1 km (10,200 ft) a.s.l. during the previous week.

Wed, 29 Oct 2008, 06:00KVERT reported that seismic activity at Karymsky was above background levels during 24-27 October and at background levels during 28-31 October. Possible explosions may have generated ash plumes to an altitude of 2.8 km (9,200 ft) a.s.l. Analysis of satellite imagery revealed a thermal anomaly in the crater on 23, 24, and 28 October; clouds prevented observations on the other days.

HVO reported that during 29 October-4 November lava flowed SE through a tube system from underneath Kilauea's Thanksgiving Eve Breakout (TEB) and rootless shield complex, reaching the Waikupanaha ocean entry. Thermal anomalies detected on satellite imagery indicated active surface flows, especially in the abandoned Royal Gardens subdivision. Explosive activity at the ocean entry was reported on 31 October and 1 November.
