Erta Ale volcano (Ethiopia): dangerous explosive activity at summit vents
Wednesday, Jul 16, 2025 | 4 months ago · T
A sudden strong explosive eruption has occurred at the summit caldera of the volcano yesterday. Dense ash plumes were seen rising about 800-1000 m above the summit and causing ash fall over the northwestern sector of the volcano.
Reports suggest that lava has returned to the northern pit crater, but …A sudden strong explosive eruption has occurred at the summit caldera of the volcano yesterday. Dense ash plumes were seen rising about 800-1000 m above the summit and causing ash fall over the northwestern sector of the volcano.
Reports suggest that lava has returned to the northern pit crater, but what exactly caused the explosive activity is unclear.
Normally, Erta Ale with its typical fluid basaltic magmas that most often forms lava lakes in the summit crater or extensive lava flows during flank eruptions or overflows from the summit vents is not producing much explosive activity of this type. This means something very unusual is taking place. One possibility is that could be related to c…Open article

Eruptive activity at Erta Ale continued during July based on satellite data and field observations. Small thermal anomalies at both the N and S pit craters were visible in periodic satellite image views on 1, 6, 8, and 11 July.

Small thermal anomalies at both the N and S pit craters were visible in periodic satellite image views on 1, 6, 8, and 11 July. On 15 July a dense black plume rising from an unstated area was filmed by a local observer and was thought to have originated from a collapse of a portion of crust covering a lava lake.
A post on social media showed pictures of the plumes and stated that the plumes sank to the ground and spread out over an area of 15 km. Plumes were visible on 16 July.

Erta Ale volcano (Danakil depression, Ethiopia): lava returns to northern pit crater, elevated activity continues
Wednesday, Apr 30, 2025 | 6 months ago · martin
A new lava effusion phase commenced at the volcano and is still continuing constantly since 2 April.
Following another shifting flux of magma, the lava returned to the northern pit crater's lava lake, generating incandescent lava flows.
The molten lava has extended towards the northern crater rim, for…Open article

Satellite images on 8 and 13 December showed a small thermal anomaly over a vent in the S Pit Crater and a smaller one over a second vent 85 m to the NW. According to a news article a local tour guide visited the area on 16 December and described “glowing rivers flowing from the southern crater”.
The two thermal anomalies and additional hot areas were present in an 18 December satellite image. The thermal anomaly pattern suggested that lava from one of the vents had flowed in between them and about 200 m SSW. A more pronounced flow, possibly from the NW vent, traveled about 100 m NW and then…Open article
