Fagradalsfjall (Reykjanes Peninsula, Iceland): Magnús Tumi Guðmundsson, a professor of geophysics, says that the new eruption is likely five-to-ten bigger than the previous eruption, but not the big one.
The new eruption poses no imminent threat to inhabitants and infrastructure as the site is far enough from the closest infrastructure. From the nearby morphology, it seems the lava flow will flow likely into Meradalir valley on the east-southeast or towards the north.

…3 Aug:
Scientists already published the exact location of the new eruption site.
The eruptive fissure is located approx. 3 km north of Langihryggur with an approx. length of 360 meters.
Fountaining continues along the full-length fissure, feeding a new lava flow field that sometimes overlaps (in the south part of the fissure) the lava flow field from the previous eruption.
…3 Aug:
The eruption continues at modest intensity (although it is likely to gradually increase), as a typical fissure eruption with lava fountains forming a „curtain of fire“ along an approx. 100 m long fissure that opened today at around 1.36 p.m. A sheet-like lava flow is slowly spreading on both sides of the fissure.
You can watch it live via the webcam of mbl.is on Youtube:

Karymsky (Kamchatka): (3 Aug) The eruptive activity of the volcano continues at moderate levels with sporadic powerful explosions as occurred at 21:44 local time yesterday.
A spectacular vulcanian eruption produced a dense grey ash plume, which reached approx. 17,000 ft (5,200 m) altitude and drifted about 12 km to the S-SW of the volcano.

Shiveluch (Kamchatka): The extrusive eruption at the volcano continues at high levels.
Hot, viscous magma continues to rise into the actively growing lava dome and piles up the material prone to collapse into glowing dome blocks and avalanches.
Ash plumes (so-called phoenix clouds) separating from avalanches reach up to approx. 15,000 ft (4,600 m) altitude as it descends the slope.
