You'll notice that Wikipedia includes it in: https://en.m.wikipedia.org/wiki/List_of_unconfirmed_impact_c...
it's existence/size/effects is controversial to say the least, TV shows about it show up on the History channel along with all the ancient aliens crap
Edit: 2min of googling and I find a not very well know 20km impact crater dated at exactly the right time (mid 15th century): https://en.m.wikipedia.org/wiki/Mahuika_crater
