Semisopochnoi (United States, Aleutian Islands): (20 Mar) The Alaska Volcano Observatory raised the alert level to „Orange“, as low-level ash emissions have continued from the north crater of Mount Young at the volcano over the past 24 hours.
Additionally, minor explosions and volcanic tremor followed during the day.

Gas and steam emissions extended about 150 km from the volcano.
This activity is comparable to the eruptive manner of the volcano observed intermittently over the past few years.

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: POSSIBLE ONGOING VA EMS. to 21000 ft (6400 m)

Santiaguito (Guatemala): Mild explosive activity continues from the volcano. The Volcanic Ash Advisory Center (VAAC) Washington reported intermittent emissions of volcanic ash plumes.
The full report is as follows: sporadic emissions of volcanic ash

Fuego (Guatemala): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 16000 ft (4900 m) altitude or flight level 160 .
The full report is as follows: CONT VA EMS to 16000 ft (4900 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 22000 ft (6700 m) altitude or flight level 220 .
The full report is as follows: ONGOING VA EMS to 22000 ft (6700 m)

Sangay (Ecuador): 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: ONGOING VA EMS to 20000 ft (6100 m)
…20 Mar:
The effusive-explosive eruption of the volcano continues.
From available webcam imagery on 18 March, it seems a fresh batch of magma has been shifting through the main conduit. Most of the red, hot fluid lava has flowed directly from the summit crater into the southeastern flank ravine. Simultaneously, strombolian activity has been picking up at the summit vent while erupting. This also confirms a stunning satellite image of the elevated effusive activity of Sangay acquired by Sentinel-2.

Near-frequent vulcanian eruptions continue to produce ash columns releasing pyroclastic material to approx. 5,8 km (19,000 ft), occasionally up to 6,1 km (20,000 ft) elevation in the eastern direction. Most of the ejected hot, juvenile and glowing material slid down along the southeastern flank in the form of incandescent avalanches.
Satellite-based measurements of SO2 concentrations were detected in plumes of about 208 tonnes on 18 March.

Reventador (Ecuador): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 14500 ft (4400 m) altitude or flight level 145 .
The full report is as follows: POSSIBLE ONGOING VA EMS. to 14500 ft (4400 m)

Cotopaxi (Ecuador): (20 Mar) Volcanic Ash Advisory Center Washington (VAAC) issued the following report: VA NOT OBSD.

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

Villarrica (Central Chile): (20 Mar) The volcano showed intense strombolian activity again last night.
After roughly one month since the last strong eruptive episode (so-called paroxysm) occurred, a vigorous lava-fountaining phase returned back to the summit vent.

Lava jets surpassed 100 meters height by ejecting hot, juvenile and plastic lava clots that landed onto the upper slopes and/or crater area accompanied by steam emissions. Sounds were heard up to 8 km from the crater.
Besides, near-frequent passive ash emissions continue to release from the crater. Grey ash columns rose about 300 meters above the crater and drifted northeast.
