Powerful high-level eruptions have been ongoing at Raikoke volcano, Russia ever-since the massive unexpected explosion that took place on June 21-22 (click here for more on that).
According to the Volcanic Ash Advisory Center (VAAC) Tokyo, today’s eruption sent volcanic ash to an estimated 38,000 feet (11.6 km) above sea level, which is now shifting at 20 kts in a NNE direction.
Particulates ejected to altitudes above 32,800 feet (10 km) –and into the stratosphere– have a direct cooling effect on the planet.
NASA has recently released an amazing photograph of the circular eruption column during Raikoke’s reawakening on June 21-22, which topped out at 43,000 ft (13 km) a.s.l..
It majestically displays circular gravity waves in the plume head.
These waves are similar to those created on water when a small object, e.g. a stone falls into it and causes a local displacement of the water that then spreads out in expanding circles.
Also just in, a passing ship has shed some light re the situation on the ground.
As expected, there is a lot of damage, clearly visible in these before and after pics:
Raikoke is a circular stratovolcano forming an island in the Central Kuriles, Russia.
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.
