Etna (Sicily, Italy): The activity continued throughout the night with a constant lava effusion from the fissure vent at the eastern base of the New SE crater and with mild strombolian activity at the summit vent.
Small explosion from Fuego volcano yesterday
Seismic tremor continued to slowly but steadily increase.
Lava continues to flow from the fissure vent at the eastern base of the New SE crater towards the Valle del Leone. Mild strombolian explosions at the summit vent accompany this activity. The tremor and the intensity of this (still weak) activity are slowly increasing.
Shiveluch (Kamchatka): More ash emissions and small to moderate explosions have occurred over the past days. An ash plume was reported at 24,000 ft (7.2 km) altitude yesterday evening.
The volcano, one of the world's most active, continues to effuse viscous lava that builds a new dome. At night, glow is visible from the vent on webcam images-.
Suwanose-jima (Tokara Islands, Japan): The remote volcano south of Kyushu remains very active, although seems to have calmed down a bit. The following video of the past 24 hours at the volcano shows phases near-continuous steam and ash emissions as well as some smaller discrete explosions. Ash plumes were reported to reach up to 4,000 ft (1.2 km) altitude.
Sinabung (Sumatra, Indonesia): A tall steam and ash plume rises from the summit crater, reaching altitudes of up to estimated 4-5 km at times.
The volcano has not produced new (or at least no larger) pyroclastic flows. Whether this is due to a true decrease in effusion rate and a possible sign of an approaching end of the eruption is difficult to say.
Dukono (Halmahera): The volcano remains in a phase of elevated strombolian-vulcanian explosive activity. A new ash plume was spotted yesterday at estimated 10,000 ft (3 km) altitude extending 40 nautical miles to the east (VAAC Darwin).
Kilauea (Hawai'i): Lava levels are rising again in Kilauea's Overlook Crater - 10 m recovered from the 20 m drop in the last week, so far.
Kilauea's summit stretched 1.5cm in the previous month then shrank 2cm over the past week! That's a lot of rock wiggling above the magma!
Santa María / Santiaguito (Guatemala): Since the morning of 23 Jan, the lava flow front at the SE rim of the Caliente dome has become more active and generated a series of collapses resulting in small pyroclastic flows that reached the base of the dome.
The volcano observatory mentions that during the recent months, activity had been elevated with 40-45 explosions typically in one day, and associated ash plumes reaching 500-900 m height.
The prevailing easterly winds cause frequent light ash fall in distances up to 10 km to the east, sometimes even in the city of Quetzaltenango.
Fuego (Guatemala): Activity at the volcano remains both explosive and effusive at fluctuating levels. After an increase during 22-23 Jan, it decreased yesterday, but seems to have picked up today again.
The latest INSIVUMEH report mentioned 13 weak and 4 moderate explosions during 23 Jan with ash plumes up to 800 m height, abundant lava avalanches on the upper slope following strombolian ejections of up to 100-150 m above the crater, and the continued active flow, which was 100 m long yesterday.
