A powerful eruption occurred at Kamchatka volcano (aka Shiveluch), Russia at 05:49 UTC March 9. The Aviation Color Code was raised to Red.
According to volcanodiscovery.com, the eruption ejected volcanic ash up to 34,000 feet (10.4km) above sea level, or 23,000 feet (7km) above the crater rim.
A moderate level of activity continues at the volcano, the KVERT observatory said, adding that ash explosions of up to 32,800 – 49,200 feet a.s.l. could occur at any time.
This rather unstable stratovolcano, with a recent eruptive history littered with VEI 4s and 5s, has seen a tremendous uptick in activity so far in 2019.
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 increase in Galactic Cosmic Rays penetrating silica-rich magma.
