I've never heard of either, but I'm very curious as to the general reaction to these phenomena, but also spiritual reaction.
I'm wondering what they did for safety, but also how they viewed them in a traditional sense.
Mentioning previous answers is not intended to discourage discussion -- further questions, information, and debate is welcome.
The FAQ has ... huh, used to have: /u/Georgy_K_Zhukov yanked it 6 months ago. Anyway, the applicable question was "How did pre-colonization, Midwest, Native Americans deal with tornados? Did they write any records of these types of storms?" at https://www.reddit.com/r/AskHistorians/comments/1ekw2j/how_did_precolonization_midwest_native_americans/ . The standards for discussion were looser then, so a lot of irrelevancy (tobacco, horses, unverified "dead man walking") and lightly sourced items are in there.
So that's just a large AskHistorians thread that could have used better scholarship, for what it's worth.
