Canlaon (Central Philippines): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTION AT 20250116/1021Z VA CLD UNKNOWN REPORTED OBS VA DTG:16/1150Z

Ibu (Halmahera, Indonesia): Volcanic Ash Advisory Center Darwin (VAAC) issued the following report: VA ERUPTION REPORTED AT 16/1806Z EST VA DTG:16/1810Z
…16 Jan:
The elevated activity from the volcano continues.
Over the past two days, stronger-than-usual explosions produced dense dark ash columns propagating towards the west-northwest. Ash emissions rose about 3-4 km above the cinder cone within the main caldera.

Following the intense eruptive period, the local observatory raised the alert level to Level IV (AWAS).
In Level IV (AWAS), people are advised to avoid the area within a radius of 4,5 km and 6 km from the crater.

Lewotobi (Flores): Volcanic Ash Advisory Center Darwin (VAAC) issued the following report: VA ERUPTION REPORTED AT 16/1310Z EST VA DTG:16/1520Z

Semeru (East Java, Indonesia): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 15000 ft (4600 m) altitude or flight level 150 and is moving at 05 kts in E direction.
The full report is as follows: VA TO FL150 REPORTED AT 16/0707Z EST VA DTG:16/0840Z to 15000 ft (4600 m)

Kilauea (Hawai’i): (16 Jan) A small, sluggish lava flow from the north vent at approximately 09:15 AM local time today, signaled a start of a fourth episode of the ongoing summit eruption.
By 09:50 local time, the lava flow activity intensified, with lava fountaining beginning around 09:55 AM local time. At the time of writing, an estimated 10 percent of the Halemaʻumaʻu crater floor is covered with the fresh lava. The webcam footage shows vigorous lava fountains reaching a height of about 60 meters (200 feet). The sluggish, low-effusion activity marking the onset of this fourth episode was shorter in duration compared to the slow starts of the second (3–4 hours) and third (2.5 days) episodes. No activity has been observed at the south vent.

The Hawaiian Volcano Observatory added: „The tiltmeter at Uēkahuna continued to record inflation beneath Halemaʻumaʻu starting around 9 a.m. yesterday, and may be starting to show signs of leveling off. Tremor increased when fountaining began, but is still lower than the first two episodes of vigorous high fountains (>250 feet or 80 meters).

Santiaguito (Guatemala): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 14000 ft (4300 m) altitude or flight level 140 .
The full report is as follows: OCNL VA EMS to 14000 ft (4300 m)

Fuego (Guatemala): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 15000 ft (4600 m) altitude or flight level 150 .
The full report is as follows: FREQUENT VA EMS to 15000 ft (4600 m)

Nevado del Ruiz (Colombia): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 19000 ft (5800 m) altitude or flight level 190 .
The full report is as follows: LGT VA EMS to 19000 ft (5800 m)

Sangay (Ecuador): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 19000 ft (5800 m) altitude or flight level 190 .
The full report is as follows: DISCRETE VA EMS to 19000 ft (5800 m)

Reventador (Ecuador): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 15000 ft (4600 m) altitude or flight level 150 .
The full report is as follows: SML VA EMS to 15000 ft (4600 m)

Vigorous fountaining from the north vent at 11:00 AM local time today (image: hawaiitracker.com)

A small, sluggish lava flow from the north vent at approximately 09:15 AM local time today, signaled a start of a fourth episode of the ongoing summit eruption.
By 09:50 local time, the lava flow activity intensified, with lava fountaining beginning around 09:55 AM local time. At the time of writing, an estimated 10 percent of the Halemaʻumaʻu crater floor is covered with the fresh lava. The webcam footage shows vigorous lava fountains reaching a height of about 60 meters (200 feet). The sluggish, low-effusion activity marking the onset of this fourth episode was shorter in duration compared to the slow starts of the second (3–4 hours) and third (2.5 days) episodes. No activity has been observed at the south vent.

The Hawaiian Volcano Observatory added: „The tiltmeter at Uēkahuna continued to record inflation beneath Halemaʻumaʻu starting around 9 a.m. yesterday, and may be starting to show signs of leveling off. Tremor increased when fountaining began, but is still lower than the first two episodes of vigorous high fountains (>250 feet or 80 meters).

If fountaining continues, it is possible that the fountain heights will increase as more gas-rich lava erupted. It is not possible to estimate how high the fountains may get or how long the fountaining will last, but prior episodes have produced fountains over 200 feet high (70 m) that last up to 24 hours.“
