Correction: as @culturevolcan pointed out, this is NOT the northeastern rift zone, but the southwestern volcano flank.

Citing: "This picture shows in fact a portion of the initial eruptive fracture cutting the upper South-West flank. Mostly gaz release a a few short lava flows there berfore the magma was drained by the North-East Rift Zone"

Looking carefully to the background you may see the South Pit and two small rounded volcanoes that are located SW of the main caldera.

@culturevolcan You're right ! I just realize that the South Pit and the two small rounded craters SW of the main caldera are visible. I was too rapid to legend this photo…

Another excellent view of the #MaunaLoa upper northeastern rift zone with the active erupting fissure in the foreground. The summit caldera is in the back.

On this image 👇🏼 , the erupting fissure with lava fountains is visible to the upper left. From the fissure reddish lava flows downslope.

Interesting National Geographic article by Robin George Andrews: "Hawaii’s #MaunaLoa erupts for the first time in 38 years. What happens next? For now, the #eruption does not threaten any populated areas, but scientists continue to closely monitor the largest active #volcano in the world."

It's dawn on the Mauna Loa #volcano summit. The USGS webcam captured daylight rising over the caldera filled by the new lava lake. Amazing view.

Webcam on the rim of Mauna Loa summit caldera shows the lava lake that started filling up few hours ago. Last #eruption at Mauna Loa was in 1984.

@Waldemar Here is a comparison of nighttime imagery few weeks before the war in #Ukraine in February, and now. I haven't explore the intrinsic variability not due to the war, but I think the difference is striking. The country is much darker now, towns are barely visible, which is at least partially due to the massive power cuts.

@Waldemar Fair comment. Will do.

After shelling of energetic infrastructures by Russia #Ukraine appears so dark on the nighttime satellite images. It looks like a desert area, but it is not.

People there are struggling with winter temperatures and war news.
