Schematic of volcanic provinces in Victoria. Older volcanics are depicted in green, Newer in orange, and Macedon – Trentham in blue. Image courtesy Meeuws, et al. https://www.sciencedirect.com/science/article/pii/S0264817216300605

 

This post will cover remaining volcanic activity in southern Australia.  The majority of it is in the southeastern state of Victoria.  The most recent activity has spilled over the border to the west into South Australia.  Finally, we will take a look at volcanic activity in the Bass Strait, the water separating Tasmania from the rest of the continent and a quick look at volcanic activity in Tasmania.

PAUL… or AVACHINSKAYA SOPKA, Kamchatka

Although I have known that the Avachinsky is one of the more active volcanoes in Kamchatka, somehow I habitually tended to skip it when checking webcams and reports for new activity in Kamchatka – I saw forever this owl face, this snow-covered, never-changing mountain… That has changed since I came across this wonderful diary by a 19th century German-Baltic geologist and explorer, K. v. Ditmar. He had lived and worked 1851-55 in Petropavlovsk, at the foot of two magnificent volcanoes. Although he didn’t manage to get to the crater – bad weather, strong gas emissions and superstitious company made him abandon two attempts – he loved volcanoes!

Australia 2 – Volcanic Activity in Northern and Central Queensland

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.
