I posted an article earlier today entitled “Monster eruption propels ash more than 13 miles into the sky” after several people sent links to me concerning the eruption.
Now, after several more readers have said they have heard nothing about such an eruption, I also question it.
I’ll check into it some more and get back to you.
Okay, I think this settles the question:
National Weather Service Retracts its Shiviluch 70k announcement
As you can see above, according to the NWS the ash plume rose to ‘only” 23,000 ft (4.37 miles).
For starters, Volcano Live by John Search does not mention it:
Volcano Discovery changes it’s tune.
As of 7:53pm, 27 August, it says:
Latest news from Shiveluch volcano
Shiveluch volcano (Kamchatka, Russia): no major eruption on 25 Aug, ash plume only to 23,000 and not 70,000 ft
The recently reported eruption on 25 Aug alerting of an ash plume as high as 70,000 ft (21300 m) did not take place. There is no data (satellite-based, direct observations etc) to confirm an eruption of this magnitude.
The report was based on an erroneous alert from the Anchorage VAAC. An eruption did take place, observed by a group of people staying nearby and who sent us images on social media, but it was “only” producing an ash column rising approx. 23,000 ft (7 km) – something not unusual for Shiveluch which has been having eruptions of this size for decades at irregular intervals.
However, VocanoDiscovery.com says it is indeed true. They say, and I quote: “Sunday, Aug 25, 2019
Here was the original post:
Monster eruption propels ash more than 13 miles into the sky
Video – Huge eruption could have a direct cooling effect on the planet.
A VEI 5/6 eruption rocked Kamchatka (Shiveluch) volcanoon Russia’s Kamchatka Peninsula over the weekend, and there’s likely more to come.
The Volcanic Ash Advisory Center (VAAC) Anchorage reported on a volcanic ash plume rising to a staggering 70,000 ft (21.3 km) into the stratosphere. Particulates ejected to altitudes above 32,800 feet (10km), and into the stratosphere, have a direct cooling effect on the planet.
This eruption at Shiveluch produced a “huge stratospheric injection” says Diamond, of the Oppenheimer Ranch Project. “We’re talking Plinian, Ultra-Plinian — one of the largest eruptions of the last decade.”
“This baby is not over.”
