I may be wrong but I don’t think Krakatoa is a super volcano, it was just a really big explosive eruption. Similar to Mt St Helen’s (smaller than Krakatoa). The shock wave for Krakatoa circled the globe 3 times, I think.
Also true, but little we can do to hedge our bets against that. My scenario? Yes. Actually, now that I think about, sufficient energy would be one of the answers to a diminishing food supply. You can grow food without natural sunlight but not without electricity.
I doubt you could grow enough food without sunlight on that sort of scale. As to solar, if the cover was so thick to make solar not work, then the cooling would be so substantial to not require air conditioning. Solar is not a big contributor in the winter. I will agree however, while I am a big fan of the prospects of solar and wind, I don’t like the idea of having to overly rely on it if for some reason it didn’t work.
I have had an intellectual fascination with Krakatoa since childhood. The scale is mind blowing, to me.
The caldera of what is called Krakatoa has erupted many times and the late l800s event of which you post is not considered the largest based on geologic studies of the area.
lettuce, greens, peppers, tomatoes, berries, etc we can grow appx 60 - 80 acres worth of food with 1 acre of greenhouse with vertical farming and hydroponics with a peat base. I have a client from Finland getting ready to build an indoor vertical farm in SW Florida. wheats and grains would be tough but I imagine they could grow rice indoors fairly efficiently too. should be interesting as they are exporting finnish greenhouse tech but to grow in warm environment. Using misters and other energy saving devices for keeping it cool so growing season is year round even when it is 100 degrees outside. regulate everything down to the amount of UV and CO2. no pesticides or fungicides
I as well, the story of the ocean liner that survived the tsunami is incredible. Imagine being on that vessel and witnessing the pyrotechnics! Not to mention a 40 meter tsunami!!
Regarding super volcanoes, imagine the Deccan Traps. As in every Super Volcano erupting simultaneously (squared). Of course that event took place over hundreds of thousands if not millions of years.
There are some great documentaries on this, one that follows the account of a British Scientist and his family, he and his wife survived the event, sadly his child did not.
I have read the book by Simon Winchester and watched some documentaries although the one you were describing does not sound familiar
One of the books I am reading now and the first chapter covers the great extinction that ended the Permian. Just wow.

Mount Etna (in Sicily) blows her top in Italy. Etna is Europe's largest and most active volcano. Snowy Mount Etna spurts lava into night sky
Krakatoa's eruption was nearly 10 times more powerful than Mt. St. Helens, at an estimated 200 megatons of TNT vs 24 MT. The 1883 Krakatau eruption: a year of blue Moons 1980 eruption of Mount St. Helens - Wikipedia
