This doctoral thesis applies measurements of ground deformation from satellite radar using their potential to play a key role in understanding volcanic and magmatic processes throughout the eruption cycle. However, making these measurements is often problematic, and the processes driving ground deformation are commonly poorly understood. These problems are approached in this thesis in the context of the Cascades Volcanic Arc. From a technical perspective, the thesis develops a new way of using regional-scale weather models to assess a priori the influence of atmospheric uncertainties on satellite measurements of volcano deformation, providing key parameters for volcano monitoring. Next, it presents detailed geodetic studies of two volcanoes in northern California: Medicine Lake Volcano and Lassen Volcanic Centre. Finally, the thesis combines geodetic constraints with petrological inputs to develop a thermal model of cooling magma intrusions. The novelty and range of topics covered in this thesis mean that it is a seminal work in volcanic and magmatic studies.

In this heart-stopping tale, the passengers of the Hudson River crash landing evoke in compelling detail the terrifying explosion as both engines were destroyed, the violent landing on the river, and the thrill of their rescue from the wings and from rafts. Jay McDonald, a thirty-nine-year-old software developer, had survived brain-tumor surgery just two years earlier and now faced the unimaginable. Tracey Wolsko, a nervous flier, suddenly became other people's rock: "Just pray. It's going to be all right." As the plane started sinking, Lucille Palmer, eighty-five, told her daughter to save herself: "Just leave me!" Featuring moments of chaos and stoicism, fortuitous mistakes and quick instincts, "Miracle on the Hudson "is the chronicle of one of the most phenomenal stories of recent years, one that could have been a nightmare and instead became a stirring narrative of heroism and hope.

This is a beautiful treasury of picture books perfect for young children. It contains five stories from the "Picture Books" series: "The Twelve Dancing Princesses", "The Three Little Pigs", "Little Red Riding Hood", "The Frog Prince" and "Goldilocks and the Three Bears". Each story is beautifully illustrated and perfect for either reading aloud or for more confident readers to tackle alone.
