Sinabung (Sumatra, Indonesia): Volcanic Ash Advisory Center Darwin (VAAC) issued the following report: GROUND REPORT OF ASH TO FL130 OBS VA DTG:24/1030Z
Dukono (Halmahera): Volcanic Ash Advisory Center Darwin (VAAC) issued the following report: CONTINUOUS VA EMISSIONS TO FL080 OBS VA DTG:24/1840Z
...24 Jan:
Volcanic Ash Advisory Center Darwin (VAAC) issued the following report: VA OBS TO FL080 MOV SW AT 24/0010Z.
Takawangha (Tanaga Island, Aleutian Islands, Alaska): The alert level of the volcano was raised to yellow as the Alaska Volcano Observatory detected an energetic earthquake swarm on Tanaga Island 6-7 km ESE of the volcano.
The seismic swarm, which includes two quakes of magnitude 4.1 and 4.4 at 7 and 10 km depth, respectively, started yesterday and is continuing. It might be caused by magma movements at depth resulting in rock-fracturing as intruding magma pressurizes the host rocks to make itself space. It might be a precursor to new activity, although most volcanic earthquake swarms do not end in an eruption (magma often is stalled underground in the process).

Bogoslof (United States, Aleutian Islands): Volcanic Ash Advisory Center Anchorage (VAAC) issued the following report: 140Z ERUPTION
...24 Jan:
Another explosion occurred at the volcano a short time ago. The Alaska Volcano Observatory reported:
"Following a period of increasing seismicity, an explosive eruption started at 04:53 AKST (13:53 UTC) this morning as shown in seismic data and by lightning detection.
We have not yet observed a volcanic cloud in satellite, but based on recent events with similar seismicity and lightning, we are raising the Aviation Color Code to RED and Alert Level to Warning." (AVO)
Colima (Western Mexico): (24 Jan) Volcanic Ash Advisory Center Washington (VAAC) issued the following report: ONGOING VA EMS
Reventador (Ecuador): Volcanic Ash Advisory Center Washington (VAAC) issued the following report: VA EMS HAS DISP
Sabancaya (Peru): Volcanic Ash Advisory Center Buenos Aires (VAAC) issued the following report: INTERMITTENT EMISSIONS OF VA OBS VA DTG:24/1705Z
...24 Jan:
Volcanic Ash Advisory Center Buenos Aires (VAAC) issued the following report: SPORADIC PUFFS OF VA OBS VA DTG:24/0515Z
Erta Ale (Danakil depression, Ethiopia): The volcanic activity at the shield volcano in the Danakil desert has been at extraordinary and very elevated levels recently. Participant returning from our recent eruption special tour (14-20 Jan) reported that during their stay 16-20 Jan, the lava lake's surface level has been undergoing rapid and large variations, producing massive lava lake overflows when high and intense spattering when low.
The activity generated a thermal signal that rose to 13 GW, a peak of approx. 100 times the normal average on 19 Dec and has stayed very high since! Following / accompanying this large surge in lava flow activity, several large collapses have been reported from both the also active northern crater and the lava lake itself on and since 20 Jan. It seems that the volcano is currently in a major phase reshaping itself.
