I originally intended to cover all volcanic fields and provinces I could find in Queensland.  Turns out there were a lot of them, so many that the post grew too large.  Will limit this post to northern and central Queensland, and bundle southern Queensland with New South Wales in Part 3, the next post.  With that being said, let’s take a look at Queensland.

Flank Collapse at Anak Krakatau, Dec. 22, 2018

Anak Krakatau a week following flank collapse eruption Dec. 22. The vent region has not yet been rebuilt above water level.
