How exactly did Native Americans deal with tornadoes? Did they take any preliminary actions?
As there were a vast multitude of different tribes within America, each tribe had a different belief and approach to these natural events. In some tribes, such as those of the Shawnee, a tornado was seen as a form of spirit which could be reasoned with and was in no way malevolent.
In other regions, particularly the south west, tornadoes and dust devils were seen as angry spirits which needed to be avoided. In general Native American tribes would either attempt to reason with the tornado or attempt to move out of its way, but there was little they could do in regards to preliminary measures other than hope it missed them.
