Pinatubo was VEI 6. St. Helens was 5, quite a bit less, 1/10th actually (log scale), and did not launch ejecta nearly as high as Pinatubo. Marapi so far is only a burp, at 10k feet plume height. Pinatubo sent stuff 28 MILES high (still a piker compared to Krakatoa’s 50 mile high plume, but while Krakatoa was incredibly violent, it’s effect on temperatures in turn was much less than Tambora, which had a plume height of only 27 miles, but a monstrous VEI of 7.
Thank You.

It’s a documentary, 54 minutes long, and quite interesting.
