Well I finally pulled the trigger on this book and ordered it on Amazon last week. Volcanism on Io: A Comparison with Earth by Ashley Davies is a comprehensive overview of the current state of knowledge into the volcanism displayed on the surface of Io. An overview of terrestrial volcanism and remote sensing studies is provided as a background to better understand what we see on Io.
The book arrived via UPS this morning and am slowly working my way through the book. I plan on providing a thorough review sometime this week on this impressive tome.
