In response to recent eruptions at Mount St. Helens and with support from the USGS Volcanic Hazards Program, the Cascades Volcano Observatory (CVO) has initiated a program to monitor all potentially-active volcanoes of the Cascade Range. As part of that effort, we installed tilt networks and obtained baseline measurements at Mount Shasta and Lassen Peak, California during July 1981. At the same time, baseline electronic distance measurements (EDM) were made and fumarole surveys were conducted by other crews from CVO. Annual surveys are planned initially, with subsequent visits as conditions warrant. These geodetic and geochemical measurements supplement a program of continuous seismic monitoring of Cascade volcanoes by the USGS Office of Earthquake Studies in cooperation with local universities. Other tilt networks were established at Mount Baker in 1975 and at Mount St. Helens in 1981. EDM networks were established at Mount Baker in 1975, Mount St. Helens in 1980, and Crater Lake in 1981. Additional tilt and/or EDM networks are planned for Mount Rainier, Mount Hood, Glacier Peak, Three Sisters, and Crater Lake as funds permit.

Describes the techniques used by volcanologists to successfully predict several volcanic eruptions by combining information from various scientific disciplines, including geodetic techniques. This book includes chapters on the developments in the use of the Global Positioning System and Synthetic Aperture Radar Interferometry techniques.

This book covers Interferometric synthetic aperture radar (InSAR) imaging of Aleutian volcanoes. InSAR is a relatively new remote sensing tool whose images enable the construction of detailed mechanical models to enhance the study of magmatic processes.
