Apocalypse

A guest post by Tallis The very worst case scenarios are rarely considered for disasters and for usually a good reason. They are either so unlikely or so boring that there is no point in worrying or thinking about it. The worst case impact event is one that would completely destroy the Earth and make…

The Missing Piece Part 3: Endgame

I have done both recently and formulated my own hypothesis, concerning silicic systems and their dynamics. After looking at the previously mentioned supercomplexes,…

The Snowdon volcano

One from the archives (from 2013, with small additions). Karen Z on Snowdonia The British Isles have an extreme diversity of geology.

The Missing Piece Part 1

Big intrusions = Big bangs? With mafic systems hogging all the attention, as a felsic guy, I feel compelled to represent my magma type.

Did you notice the erupting Supervolcano?

The Look and Feel of VC

As some of you will no doubt be aware, a recent WordPress update has messed up how the comments section in particular is displayed on mobile devices. This is something outwith our control. The Plugin which provides a lot of our back end goodness has decided that as most “modern” themes are natively responsive (i.e.…
