Toba
Try Toba (Sumatra) which erupted about 74,000 years ago.
​
Super volcano about 10,000 times Mt. St. Helens.
​
I recall reading that human populations (from genetic studies) bottlenecked (some speculate) to less than 50 fertile females.
​
Will need to do some research to find the data later if I'm not too lazy.
