was there a volcano eruption in 1816, the largest in the world?

Answer 1

No, in 1815 !!

5 April, 1815, on the island of Sumbawa in Indonesia - the explosion of the great Tambora volcano = the Greatest Volcanic Eruption in Recorded History

Answer 2

The eruption of Mount Tambora sent more dust into the upper air to obscure sunlight than any other over the last 400 years. [No mention of the "Dark Ages" in the sixth century, a world-wide phenomena.] Tambora had 10 times more volume than Krakatoa in 1883, 100 times more volume than St. Helens in 1980. Krakatoa reduced direct sunlight by 15% to 20% (p.10). Science knows quite a lot about the cold summer of 1816 because of scientific observation at the time. June 6, 1816 saw unseasonable cold and snow!

I don't think the largest in the world, but certainly the largest in the past couple of centuries... If its effect was strong enough to reduce sunlight by 15%... Dear God. It actually erupted in 1815... "Mount Tambora erupted on April 10, by most accounts, and the eruption lasted from April 10 to April 15 "but the year after (1816) was nicknamed "The Year Without A Summer" because it was so freaking cold... (decreased about 0.5 degrees Farenheit)

Answer 3

Krakatoa

Answer 4

Nope!
