Book review: Volcanoes and the Making of Scotland, by Brian Upton

02/02/2017

I remember reading and enjoying this book when the first edition came out many years ago. I am also a keen hillwalker and have stood on top of many of the Scottish mountains referred to in the text. In fact, I particularly enjoyed climbing Ben More on the island of Mull, which I remember reading was the last volcano in northwest Europe.

Book review: Vesuvius: A Biography, by Alwyn Scarth

23/08/2013

Vesuvius is a European geological icon par excellence. There are many books about this wonderful volcano and most people will know of its connection with the destruction of Pompeii. However, this book is as much about its social history, as it is about geology.
