Stromboli (Eolian Islands, Italy): As night falls, one can see strong glow from the craters and continuing frequent, typical strombolian explosions of medium to large size (but within the levels of activity often observed at the volcano).
A weakly alimented lava flow is present on the upper Sciara del Fuoco. Today's larger blast seems to have removed all or most of the large cinder cone that had dominated the northern crater area (see images before / after attached for comparison). The blast itself was likely the consequence of a gas-rich surge of fresh magma that quickly rose and exploded at the vents. Immediately before, its rise had pushed the overlying magma column out, which explains the lava overflow observed before the eruption.

Unfortunately, today's eruption has also claimed at least one life.
According to news reports a tourist was killed by a falling bomb and another one was injured.

...3 Jul:
A series of at least two very large explosions occurred this afternoon at the volcano. They probably rank among the largest recorded at the volcanoes in decades.
At approx. 16:51, 16:54, and 17:03 local time, it seems that the the western (or otherwise the central) vent produced powerful eruptions (in particular the latter two), which ejected glowing bombs all over the summit area and produced an eruption column that rose approx. 3-5 km.

Klyuchevskoy (Kamchatka): (2 Jul) Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTION FL200 EXTD SE REPORTED AT 20190702/2302Z OBS VA DTG:02/2250Z

Shiveluch (Kamchatka): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Tokyo warned about a volcanic ash plume that rose up to estimated 13000 ft (4000 m) altitude or flight level 130 and is moving at 5 kts in SE direction.
The full report is as follows: VA AT 20190703/1840Z FL130 EXTD SE OBS VA DTG:03/1840Z to 13000 ft (4000 m)

Mayon (Luzon Island, Philippines): The volcano has been showing signs of unrest and it is likely preparing for its next eruption although it is left to speculation when it will start.
During the reported 24-hour interval, the monitoring network recorded 7 volcanic earthquakes and one rockfall event. Weak to moderate emission of white steam-laden plumes were observed, PHIVOLCS reported.
"Sulphur dioxide (SO2) emissions were measured at an average of 680 tonnes/day on 14 June 2019 and precise leveling data obtained on 09 – 17 April 2019 indicate a slight inflation of the edifice relative to 20 – 26 March 2019. This is consistent with continuous GPS data showing that the edifice is still inflated since June 2018."

Krakatau (Sunda Strait, Indonesia): (2 Jul) Volcanic Ash Advisory Center Darwin (VAAC) issued the following report: ERUPTION REPORTED BY GROUNG OBSERVER AT 02/2207Z

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 and is moving at 5 kts in E direction.
The full report is as follows: CONTINUOUS VA TO FL070 LAST OBS 03/0230Z EXT E to 7000 ft (2100 m)

Mauna Loa (Big Island, Hawai'i): (3 Jul) The alert level for the volcano has been raised to yellow two days ago. This doesn't mean that an eruption is expected to occur in a near future, but acknowledges that the volcano is currently preparing itself for its next eruption, which will come, sooner or later, but currently without possibility to indicate a specific time frame.
The Hawaiian Volcano Observatory (HVO) reported that "for the past several months, earthquake and ground deformation rates at Mauna Loa Volcano have exceeded long term background levels. An eruption is not imminent and current rates are not cause for alarm. However, they do indicate changes in the shallow magma storage system at Mauna Loa."
