A powerful high-level eruption unexpectedly started at Raikoke volcano, Kuril Islands, Russia at around 17:50 UTC on June 21, 2019 — with the massive explosive activity continuing into June 22.
According to the Volcanic Ash Advisory Center (VAAC) Tokyo, a near-constant column of thick volcanic ash is rising to 43,000 feet (13.1 km) above sea level, and comfortably into the stratosphere.
Particulates ejected to altitudes above 32,800 feet (10 km) have a direct cooling effect on the planet.
The ash plume is clearly visible on satellite imagery, rising high above the dense lower cloud deck:
Unexpected eruptions like this can prove disastrous for aviation, with the ejected ash easily disabling a jet engine.
The airspace above the Central Kuriles is popular for flights between N-America and NE-Asia. And barely minutes after the eruption started, the VAAC Tokyo had already issued world-wide aviation warnings.
Raikoke is a circular stratovolcano forming an island in the Central Kuriles.
Its last eruption was back in 1924 (solar minimum of cycle 15), which ranked as a 4 on the Volcanic Explosivity Index.
It also has two previous confirmed eruptions, one in 1778 (VEI 4) and another in 1765 (VEI 2) — both blowing just after the Maunder Minimum.
Stratovolcano: 551 m / 1,808 ft
Central Kuriles: 48.29°N / 153.25°E
Current status: ERUPTING (4 out of 5)
Eruption list: 2019-ongoing, 1924, 1778, 1765

Seismic and Volcanic activity has been correlated to changes in our sun.
The recent global uptick in earthquakes and volcanic eruptions is likely attributed to the drop-off in solar activity, coronal holes, a waning magnetosphere, and the influx of Cosmic Rays penetrating silica-rich magma.
