Map of today’s active volcanoes

Svartsengi (Reykjanes peninsula, SW Iceland): (27 Aug) A new series of satellite imagery of the effusive eruption on the Reykjanes Peninsula has been processed.
The latest Sentinel-2 acquisition from 26 August portrays a relatively cloud-free image of the eruption site.
The lava flow occupies mostly the northwestern part of the fissure, concentrated in two main lava flow streams.
…27 Aug:
The ongoing eruption is the largest in the area since the autumn of 2023, the Icelandic Met Office reported.
Model calculations estimate the volume of magma that flowed from Svartsengi into the Sundhnúks crater series when the eruption started.

The eruption continues northeast of Stóra-Skógfell, with activity becoming more concentrated in one area north of the fissure. The lava continues to flow northwest in two main streams, though its progress has significantly slowed.
It is estimated that the lava flow is currently several tens of cubic meters per second. Although exact measurements have not yet been made, this estimate is based on comparisons with previous eruptions in the area and visual assessments of crater activity. At the start of the eruption, the lava flow was estimated at around 1,500 to 2,000 cubic meters per second, meaning the current activity is only a fraction of what it was initially.

White Island (New Zealand): Volcanic Ash Advisory Center Wellington (VAAC) issued the following report: ERUPTION AT 20240812/1320Z CONTINUOUS LOW LEVEL ERUPTION
…27 Aug:
The observation flight confirmed that activity is concentrated in the single active vent on the crater floor.
The vent emits an ash plume that rises to an altitude of 600-900 meters before being dispersed downwind. An ashfall is limited to within 1 km of the island.

Thermal infrared imagery taken during the flight indicated a vent temperature of approximately 590 °C.
Additionally, webcams in Whakatāne and Te Kaha have recorded the plume reaching an altitude of around 2 km under calm conditions. The NZ MetService also utilizes satellite imagery to monitor the ash plume, which can be tracked for tens of kilometers downwind when skies are clear.

Fuego (Guatemala): Volcanic Ash Advisory Center Washington (VAAC) issued the following report: POSS VA EMS

Sabancaya (Peru): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Buenos Aires warned about a volcanic ash plume that rose up to estimated 25000 ft (7600 m) altitude or flight level 250 and is moving at 15 kts in SE direction.
The full report is as follows: PUFF EMISSIONS to 25000 ft (7600 m)
