The location of recorded earthquakes over the past week (C) U.S. Geological Survey
Stromboli (Eolian Islands, Italy): The activity of the volcano has increased during the past days and is classified as "high", with very frequent and often strong strombolian explosions from several vents.
Data analysis shows that some explosions are accompanied by strong acoustic pressure waves (up to 4 bar) and send lava bombs flying with initial exit speed of 47 m/s. Seismic activity includes so-called long period events reflecting internal magma movements.

Aso (central Kyushu, Japan): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ACTIVITY CONT. VA AT 20200221/1800Z FL050 EXTD N OBS VA DTG:21/1750Z

Kuchinoerabu-jima (Ryukyu Islands): (21 Feb) Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTED AT 20200221/0158Z FL030 STNR OBS VA DTG:21/0150Z

Sakurajima (Kyushu, Japan): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: EXPLODED AT 20200221/1341Z FL070 EXTD E OBS VA DTG:21/1330Z

Dukono (Halmahera): (21 Feb) Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 7000 ft (2100 m) altitude or flight level 070 and is moving at 15 kts in SW direction.
The full report is as follows: CONTINUOUS VA EMISSION TO FL070 OBS EXT SW AT 21/0040Z to 7000 ft (2100 m)

Mauna Loa (Big Island, Hawai'i): HVO recorded 44 small-magnitude earthquakes beneath Mauna Loa volcano's upper elevations. The strongest was a magnitude-2.2 on the 16th of February, at approximately 7 kilometers (around 4 miles) below the surface. This was deeper than most of the earthquakes which occurred at depths of less than 5 kilometers (around 3 miles) beneath the surface of the volcano. The volcano continues to inflate, due to magma being supplied to the volcano’s shallow storage region. Gas concentrations and fumarole temperatures remain stable.

Popocatépetl (Central Mexico): Volcanic Ash Advisory Center Washington (VAAC) issued the following report: VA SEEN ON WEB CAM AND VOLCAT ALERT.

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: ONGOING VA EMS. to 15000 ft (4600 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: VA TO FL220 RPRTED BY MWO 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: VA AND GASES SEEN IN SAT. to 20000 ft (6100 m)

Reventador (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 AND PIREP. to 20000 ft (6100 m)

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