Volcano Deformation Geodetic Monitoring Techniques /

Volcanic Deformation is the first book devoted to volcano geodesy, a specialisation of the still-young science of volcanology. It forms a part of the whole catalogue of methods used to monitor a restless or an erupting volcano, and demonstrates how risk from hazardous eruptions can be reduced. With...
