Shiveluch Volcano Eruption Update; Large & Sustained Explosive Eruption, Widespread Ashfall

The most explosive volcano in Russia just produced its largest eruption in 30 years, sending a several hours long and sustained plume of ash to a height of more than 50,000 feet for more than 6 hours. As a result, large pyroclastic flows were generated from Shiveluch and significant swaths of Kamchatka were coated in a layer of as much as 10 centimeters thick of ash. What had just occurred was a sub-plinian eruption from a volcano which famously produced a large partial collapse and debris avalanche during a 1964 eruption. Note: The evacuation radius/exclusion zone is purely hypothetical and based only off of the opinion of GeologyHub based on the situation at Sheveluch and no other volcanoes on April 11 2023 and does not represent a government or agency opinion. Update on April 14, 2023. In my opinion the maximum exclusion zone should now be 20 kilometers instead of 35 kilometers. This is also not an official government or agency opinion. Update on April 22, 2023. In my opinion the maximum exclusion zone should now be 15 kilometers instead of 20 kilometers. This is also not an official government or agency opinion.
