Due to poor weather conditions in the eruption area, the site will be closed to tourists today.
A yellow weather alert status is in effect for the southwestern part of Iceland as a storm can reach up to 13-20 m/s accompanied by rain. Strong wing gusts are expected to occur near the Kjalarnes and Hafnarfjall mountains, likely to exceed 25 m/s.
Very poor conditions for outdoor activities such as hiking.
Ibu (Halmahera, Indonesia): The surveillance cameras of the PVMBG observatory observed a fairly strong eruption at the level of the volcano at 2:54 p.m. local time yesterday.
A growing gray ash plume was observed rising to an estimated altitude of 2.8 km and spreading southward.

Erta Ale (Danakil Depression, Ethiopia): Our expedition leader and VolcanoDiscovery Ethiopia guide, Enku Mulugeta, visited the volcano in early August to make new observations.
The lava lake continues to occupy the central part of the south crater eruption of small lava fountains. Continuous spatter continues to eject hot, juvenile, plastic lava fragments to form small stalactites at the bottom of the lava field.
Simultaneously, the north pit crater began building rare Hawaiian-like phenomena, a fragile, steep-sided splash cone (also called a hornito) resulting from vigorous lava spattering. This volcanic feature is formed when part of the lava, flowing into the lava tube, escapes through a hole out of the lava tube due to strong outgassing in the form of spattering.
