# How powerful was Arizona's Sunset Crater eruption?

(Asked by: username_0 on 2024-10-29)

In around 1100 CE, maybe 20 miles from Flagstaff, AZ, [Sunset Crater](https://en.wikipedia.org/wiki/Sunset_Crater) erupted.

My question is... how powerful was this eruption? Like where on the [VEI scale](https://en.wikipedia.org/wiki/Volcanic_explosivity_index) would it have likely fallen?
