Map of today’s active volcanoes

Lewotobi (Flores): (7 Feb) The effusive-eruptive eruption of the volcano continues.
The lava on the north-northeast flank remains active, feeding the flow that advances slowly through the edifice’s foothills on the northeast. The lava development is well documented in the attached SAR (Synthetic Aperture Radar) visualization within a one-month (6 Jan-6 Feb) time range.

The explosive activity continues from the crater, characterized by sporadic explosions rising to estimated 2,3 km altitude towards the north.
The volcano observatory reported a seismic signal with a maximum amplitude of 47 mm and a duration of 75 seconds.

Semeru (East Java, Indonesia): (6 Feb) 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 .
The full report is as follows: VA TO FL150 MOV EAST OBS VA DTG:06/2257Z to 15000 ft (4600 m)

Popocatépetl (Central Mexico): 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: OCNL VA EMS to 20000 ft (6100 m)

Santiaguito (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: NEW VA EMS to 15000 ft (4600 m)
…7 Feb:
The extrusive-explosive eruption of the volcano continues.
A visible night-time glow and abundant near-constant emissions of gas and water vapor (so-called degassing), rising 300 meters above the crater in the SW direction, indicate the continuing rise of fresh viscous magma accumulating into the Caliente lava dome. Pilling lava material makes the dome partially prone to collapse, which in turn develop into rolling hot weak-to-moderate avalanches and incandescent dome blocks in the W-SW direction along the steep ravines.

The explosive activity is characterized by near-constant weak-to-moderate vulcanian-sized eruptions. Viscous, but gas-poor magma squeezes through the main conduit in search for the fastest way up to the surface and is being fragmented into grey ash-rich eruption plumes, reaching an average height of about 10,800 ft (3,3 km).
People are advised to avoid the sticky lava flow due to the strong heat which may cause burns and other serious injuries. The current hazards are also hot avalanches that can become mobilized into hot glowing currents (pyroclastic flows).

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: VA EMS CONT to 15000 ft (4600 m)

Nevado del Ruiz (Colombia): Volcanic Ash Advisory Center Washington (VAAC) issued the following report: NO VA OBS

Reventador (Ecuador): 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 .
