Map of today’s active volcanoes

Reykjanes (Reykjanes peninsula (SW Iceland)): Based on the latest data, scientists from the Icelandic Meteorological Office (IMO) and the University of Iceland concluded that a new eruption in the Svartsengi region on the southern peninsula is becoming more and more likely.
According to their data, approximately 6.5 million cubic meters of magma has accumulated beneath the area as of Feb 1st, 2024, and the volume of magma will soon reach the same level as during the January 2024 eruption. „Therefore, the timescale for the next eruption could be within two weeks or possibly days. This means that the likelihood of a magma intrusion, and a volcanic eruption, have increased.“

It would be the 3rd eruption in the same area within only about 2 months, and the 6th since Iceland’s southern rift zone awakened in early 2021. It is believed that after about 800 years of dormancy, the volcanic rift of the Reykjanes peninsula is now in a new phase of activity, characterized by possibly many consecutive volcanic eruptions along various sections of the rift during the years and possibly few decades to come.

Ibu (Halmahera, Indonesia): (1 Feb) The powerful eruptive activity at the volcano goes on.
Stronger-than-usual explosions continue to be observed from the cinder cone within the summit caldera. At midnight last night, a tall, dense grey ash column could be seen rising to estimated 3,300 meters (10,800 ft) height towards the southeast. In addition, several minutes before the eruption, a vivid night-time glow accompanied an explosion, which might suggest a new magma influx to the volcano’s feeder pipe.

The seismic network reported signal with maximum amplitudes of 28 mm and a duration of 186 and 130 seconds.
The continuing lava dome is actively growing as viscous magma continues to rise into it and form a faint glow on the top of the dome. Thus, it extrudes lava dome blocks into slowly advancing lava flow (so-called coulée) on the northern flank.

Lewotolo (Lesser Sunda Islands): The effusive-explosive eruption at the volcano continues.
Ocassional strombolian and larger vulcanian-type explosions continue to take place from the crater within the main caldera.

Viscous, gas-poor magma continues to squeeze through the 2020 cinder cone’s conduit in search for the fastest way up to the surface and is being fragmented into incandescent lava bombs and fine-grained tephra. Grey ash plumes rose to a height of 6,300 ft (1,9 km) and drifted northeast today.
The sluggish-paced viscous lava, effusing from the 2020 cinder cone, continues to fill the main caldera mostly.

Semeru (East Java, Indonesia): (31 Jan) Volcanic Ash Advisory Center Darwin (VAAC) issued the following report: GROUND REPORT OF ERUPTION WITH VA TO FL140 OBS VA DTG:31/2138Z

Kilauea (Hawai’i): (1 Feb) The activity beneath the volcano’s summit has been picking up and energizing over the past hours and is still continuing.
The summit area is being pressurized. The elevated seismic activity is confined to the summit region only, no unusual activity has been detected in the Southwest Rift Zone.

Earthquakes have been more frequent under the caldera in the south early this morning but have fluctuated in intensity throughout the day and remain high in general.
Since 03:00 AMP local time, the number of quakes has been varying between 25-40/hour at a 1.5-3 km depth. Quakes have shifted in clusters between the area just south of Halema’uma’u and the region southwest of the outer caldera boundary.

Popocatépetl (Central Mexico): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 21000 ft (6400 m) altitude or flight level 210 .
The full report is as follows: VA EMS OBS to 21000 ft (6400 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: LGT VA EMS to 15000 ft (4600 m)

Reventador (Ecuador): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 17000 ft (5200 m) altitude or flight level 170 .
The full report is as follows: VA EMS OBS to 17000 ft (5200 m)

Sabancaya (Peru): Volcanic Ash Advisory Center Buenos Aires (VAAC) issued the following report: SPORADIC EMISSIONS

The overall assessment for each zone is based on a combined evaluation of seven types of hazards that could occur within individual zones. The list on the map shows hazards within the zones that are rated as "considerable", "high," or "very high". Hazards rated as "high" or "very high" are highlighted in bold. It should be noted that although the overall hazard assessment for Grindavík remains the same as last week, the lava-flow hazard is now assessed as high. The hazard of sinkholes opening over fissures within Grindavík is still rated as very high. (image: IMO)
