This one has potential to block infrared due to the sulphur particles in the ejecta. The closer to the equator, the greater the impact on temps worldwide. Think Pinatubo compared to St Helens. The former cooled the planet. The latter had neglible impact.
-70 climbers were on the mountain when the eruption happened and they got trapped in the area.
- Rescue teams were able to rescue 28 climbers while 42 others are still trapped in the mountain.
How does this one compare to Pinatubo?
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.
