Ebeko (Paramushir Island): (30 Jul) Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTION AT 20200730/2108Z FL090 EXTD NE REPORTED OBS VA DTG:30/2120Z

Nishino-shima (Volcano Islands, Japan): Volcanic Ash Advisory Center Washington (VAAC) issued the following report: NOT AVBL

Suwanose-jima (Ryukyu Islands): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTED AT 20200731/1836Z FL080 EXTD W OBS VA DTG:31/1830Z

Manam (Papua New Guinea): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin 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: CONTINUOUS VA PLUME TO FL140 MOVE NW. to 14000 ft (4300 m)

Ibu (Halmahera, Indonesia): (31 Jul) Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 6000 ft (1800 m) altitude or flight level 060 .
The full report is as follows: REGULAR DISCRETE VA ERUPTIONS TO FL060 OBS AT 30/2350 MOV NW to 6000 ft (1800 m)

Dukono (Halmahera): 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 .
The full report is as follows: CONTINUOUS VA EMISSION TO FL070 MOV NW OBS VA DTG:31/1940Z to 7000 ft (2100 m)

Mauna Loa (Big Island, Hawai'i): (30 Jul) The Hawaiian Volcano Observatory recorded 105 small-magnitude earthquakes on Mauna Loa’s summit and upper-elevation flanks over the past week. Most of these earthquakes occurred at shallow depths of less than 8 kilometers (~5 miles) below ground level.

There is continued slow summit inflation, consistent with magma supply to the volcano's shallow storage system. Gas concentrations and fumarole temperatures at the Summit and Sulphur Cone monitoring sites remain stable (below 2 ppm SO2, ~98 C respectively). Webcams show no changes to the landscape.

Makushin (Aleutian Islands): (30 Jul) The Alaskan Volcano Observatory (AVO) report that the small earthquakes which began on June 15 continues. These earthquakes are located southeast of the summit. No activity was observed in cloudy satellite and web camera imagery.

AVO mention that the earthquake sequence may be associated with volcanic unrest, but there have been no signs of deformation or surface activity noted in other monitoring data. Should an eruption occur, it would be likely to see additional signs of unrest prior to the onset. Also, the main hazard would likely be from airborne ash and ash fall.

Veniaminof (Alaska Peninsula, USA): (30 Jul) The Alaska Volcano Observatory (AVO) report low-level seismic unrest at Veniaminof volcano continues. No explosive activity was detected by regional infrasound sensors. A small steam plume was observed in a partly cloudy satellite image.

Great Sitkin (United States, Aleutian Islands): (30 Jul) The Alaskan Volcano Observatory (AVO) report low-level unrest at Great Sitkin continues. Occasional small local earthquakes have occurred at the volcano over the past day. No explosive activity was detected by infrasound sensors. No activity was observed in cloudy satellite and web camera imagery.

Popocatépetl (Central Mexico): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 23000 ft (7000 m) altitude or flight level 230 .
The full report is as follows: RESIDUAL VA to 23000 ft (7000 m)

Fuego (Guatemala): (31 Jul) 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 SEEN IN SAT to 15000 ft (4600 m)

Sabancaya (Peru): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Buenos Aires warned about a volcanic ash plume that rose up to estimated 21000 ft (6400 m) altitude or flight level 210 and is moving at 10 kts in S direction.
The full report is as follows: INTERMITTENT PUFF EMISSIONS to 21000 ft (6400 m)
