In summary, on Tuesday, the Shiveluch volcano on Russia's Kamchatka Peninsula erupted, spewing ash and dust 20 kilometers into the sky and covering a wide area with ash. The ash cloud extended over 500 kilometers northwest, leading to the closure of skies for aircraft and advisories for residents to stay indoors and schools to be shut down. The eruption also caused power outages in some villages and was described as the biggest fallout in nearly 60 years. The volcano is one of the largest and most active in the region, with frequent eruptions and dome collapses. The recent eruption was predicted a few days earlier by a geology expert.

The Shiveluch volcano erupted early Tuesday on Russia’s far eastern Kamchatka Peninsula, spewing clouds of dust 20 kilometers (65,600 feet) into the sky and covering broad areas with ash.

The ash cloud from the eruption of Shiveluch, one of Kamchatka’s most active volcanoes, extended over 500 kilometers (more than 300 miles) northwest and engulfed several villages in grey volcanic dust.

Officials closed the skies over the area to aircraft. Local authorities advised residents to stay indoors and shut schools in several affected communities. Two villages had their power supplies cut for a few hours until emergency crews restored them.

Ash fell on 108,000 square kilometers (41,699 square miles) of territory, according to the regional branch of the Russian Academy of Sciences Geophysical Survey. Scientists described the fallout as the biggest in nearly 60 years.

The village of Klyuchi, which is located about 50 kilometers (some 30 miles) from the volcano, was covered by an 8-centimeter (3-inch) layer of dust. Residents posted videos showing the ash cloud plunging the area into darkness.

Geological Summary. The high, isolated massif of Sheveluch volcano (also spelled Shiveluch) rises above the lowlands NNE of the Kliuchevskaya volcano group. The 1,300 km3 andesitic volcano is one of Kamchatka's largest and most active volcanic structures, with at least 60 large eruptions during the Holocene. The summit of roughly 65,000-year-old Stary Shiveluch is truncated by a broad 9-km-wide late-Pleistocene caldera breached to the south. Many lava domes occur on its outer flanks. The Molodoy Shiveluch lava dome complex was constructed during the Holocene within the large open caldera; Holocene lava dome extrusion also took place on the flanks of Stary Shiveluch. Widespread tephra layers from these eruptions have provided valuable time markers for dating volcanic events in Kamchatka. Frequent collapses of dome complexes, most recently in 1964, have produced debris avalanches whose deposits cover much of the floor of the breached caldera.

My wife listened to a report a couple of days ago, and the alert was orange, with some eruption expected. Well about 2 days later - it did.
I believe it was the guy who does GeologyHub
