Map of today’s active volcanoes

Reykjanes (Reykjanes peninsula (SW Iceland)): (26 Mar) The eruption has subsided over the past 24 hours.
The magma supply towards cinder cone vents decreased and it seems that the activity in smallest cones will cease soon.

Lava flows continue to travel southward and then turn to the west. Over the weekend, the lava already filled up the Melhólsnámina, but the closer to the crater, the thicker it is.
GPS measurements indicate the ongoing swelling of the Svartsengi area but at reduced levels.

Ibu (Halmahera, Indonesia): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 12000 ft (3700 m) altitude or flight level 120 .
The full report is as follows: DISCRETE VA EMISSION TO FL120 MOV W OBS VA DTG:26/1320Z to 12000 ft (3700 m)
…26 Mar:
The eruptive activity continues.
The volcano’s behavior is characterized by a combination of near-constant moderate and sporadic strong vulcanian-type explosions from the caldera’s cinder cone over the past few weeks.

Vigorous eruptions appeared at the volcano at 07:47 and 18:19 local time yesterday and generated grey ash plumes rising 1,5 and 2 km above the crater, respectively. Ash emissions extended west.
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.

Semeru (East Java, Indonesia): Volcanic Ash Advisory Center Darwin (VAAC) issued the following report: VA ERUPTION REPORTED AT 26/0915Z EST VA DTG:26/0920Z

Marapi (Western Sumatra, Indonesia): Volcanic Ash Advisory Center Darwin (VAAC) issued the following report: CONTINOUS VA EMISSION REPORTED TO FL140 MOV W AT 26/1713Z

Ruapehu (North Island): (26 Mar) In early March 2024, a series of small earthquakes has been occurring at the volcano.
Small-sized quakes are difficult to identify via seismic networks as the volcano observatory measures larger events. Over the past month, a maximum of six such earthquakes have been registered. Earthquakes consist of 10-minute ground oscillation and several sub-events. Such earthquakes do not represent volcanic tremor and are quite distinguishable from volcanic tremor as seen at Ruapehu.

The GeoNet added: „While we are able to determine a location for some of the larger examples, the small size and style of the activity means our locations, especially depth, are quite uncertain. However, as they are recorded only by monitoring stations on the upper part of the volcano, we speculate that they originate near the summit area of the volcano within a few kilometres’ depth beneath the surface.
While the earthquakes represent something new at Ruapehu, and we are working on understanding the details of the processes driving them, they are not thought to pose any concerns for eruptive activity. Other monitored parameters have shown no recent changes. The temperature of Te Wai ā-moe (Crater Lake) is now relatively stable at about 24 ºC, recent observations of the lake recognised nothing unusual, gas emissions from Ruapehu remain moderate, and volcanic tremor is low.“

Popocatépetl (Central Mexico): 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: VA EMS CONT to 19000 ft (5800 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: FRQ VA EMS to 15000 ft (4600 m)

Nevado del Ruiz (Colombia): (26 Mar) Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 20000 ft (6100 m) altitude or flight level 200 .
The full report is as follows: VONA RPRT RCVD to 20000 ft (6100 m)

Reventador (Ecuador): Volcanic Ash Advisory Center Washington (VAAC) issued the following report: NO VA OBSD

Sabancaya (Peru): Volcanic Ash Advisory Center Buenos Aires (VAAC) issued the following report: UNABLE TO DETECT

The activity in craters continues at diminished levels (image: Live from Iceland webcam)
