Redoubt Rumbles

Unrest at Redoubt Volcano continues, though no eruption has yet occurred. Seismicity levels have increased since yesterday evening and have also risen markedly over the last hour. Pilot reports, clear AVO webcam views, and satellite and radar views confirm that Redoubt Volcano has not yet erupted at the time of this report. Redoubt remains at [...]

Kliuchevskoi, Kamchatka, Russia

KVERT reported that seismic activity at Kliuchevskoi was above background levels during 1-9 January. Strombolian activity and lava effusion on the NW flank continued. Analysis of satellite imagery revealed a large daily thermal anomaly in the crater. Ashfall was reported in Kozyrevsk village (about 50 km W) on 1 January. Ash plumes drifted 60 km [...]

Kilauea, Hawaii, USA

HVO reported that during 7-13 January lava flowed SE through a tube system from underneath Kilauea’s Thanksgiving Eve Breakout (TEB) and rootless shield complex, reaching the Waikupanaha ocean entry. Surface flows were noted on the coastal plain and incandescence was seen at the base of the pali. Explosions at the ocean entry were seen on [...]

Karymsky, Russia

KVERT reported that during 2-9 January seismic activity from Karymsky was not evaluated due to technical issues. Analysis of satellite imagery revealed a thermal anomaly in the crater on 7 January; clouds prevented observations on the other days. The Level of Concern Color Code remained at Orange.

Fuego, Guatemala

INSIVUMEH reported that during 8-9 January, multiple explosions (3-5 per hour) from Fuego produced ash plumes that rose to altitudes of 4.3-5.4 km (14,100-17,700 ft) a.s.l. and drifted 10-15 km S and SW. The explosions produced rumbling sounds and shock waves that were detected 10-15 km away. Ashfall was reported in areas downwind. Constant avalanches [...]
