Aso (central Kyushu, Japan): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: POSS ACTIVITY CONT. VA CLD UNKNOWN AT 20200215/1800Z

Sakurajima (Kyushu, Japan): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: EXPLODED AT 20200215/1228Z VA CLD UNKNOWN OBS VA DTG:15/1220Z

Dukono (Halmahera): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 8000 ft (2400 m) altitude or flight level 080 and is moving at 10 kts in SW direction.
The full report is as follows: CONTINUOUS VA EMISSIONS TO FL080 EXT W/SW LAST OBS 15/0120Z to 8000 ft (2400 m)

Mauna Loa (Big Island, Hawai'i): (14 Feb) 31 small-magnitude earthquakes occurred beneath Mauna Loa over the past week. HVO recorded the strongest earthquake at magnitude 2.9, 13 km (8 miles) deep on February 9. According to HVO this was deeper than most earthquakes from the past week, which occurred less than 5 km (3 miles) deep. There is continued inflation at the summit where magma supply to the volcano’s shallow system continues.

“Gas concentrations at the Sulphur Cone monitoring site on the Southwest Rift Zone remain stable. Fumarole temperatures as measured at both Sulphur Cone and the summit have not changed significantly.”

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: CONT NEW VA EMS to 21000 ft (6400 m)

Sangay (Ecuador): 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 CLD OBS IN STLT. to 19000 ft (5800 m)

Reventador (Ecuador): (15 Feb) 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 .
The full report is as follows: VA EMS CONTINUE to 14000 ft (4300 m)

Sabancaya (Peru): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Buenos Aires warned about a volcanic ash plume that rose up to estimated 28000 ft (8500 m) altitude or flight level 280 and is moving at 10 kts in S direction.
The full report is as follows: continuous ash emissions to 28000 ft (8500 m)

Nevados de Chillán (Central Chile): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Buenos Aires warned about a volcanic ash plume that rose up to estimated 13000 ft (4000 m) altitude or flight level 130 .
The full report is as follows: ISOLATED PUFF OF VA to 13000 ft (4000 m)

Piton de la Fournaise (La Réunion): It is currently unclear whether the eruption still continues. The volcano observatory reported a sudden strong decrease in volcanic tremor was detected this afternoon at 14:00 local time, which probably means that magma supply drastically dropped or even ceased.
A small tremor signal was again detected half an hour later at the stations closest to the eruptive site.
