Geodesy is concerned with the measurement of position and movement of points on the earth's surface. Its geophysical applications provide insights into many of the processes central to the earth and environmental sciences. Variations in the height of the ocean surface reflects variations in the earth's gravity field caused by thermally driven motion in the solid mantle, the mechanism that is the basic driving mechanisms for the motion of the plates. Measurements of position and changes in position made with the Global Positioning System (GPS) shows the patterns of deformation associated with the movement of the continents and mountain building, and help identify the forces causing them. A technique called interferometry that uses satellite radar observations can reveal what happens at depth on fault planes during earthquakes.
Over the past six years, much of my research has been carried out with colleagues and students in the Centre for the Observation and Modelling for Earthquakes and Tectonics (COMET), of which I am the director. This is an Earth Observation Centre of Excellence supported by the Natural Environment Research Council (NERC) that links scientists at several earth sciences and geomatic engineering departments. COMET has recently evolved into one of the science themes supported by the new National Centre for Earth Observation (NCEO), that on the Dynamic Earth and Geohazards. This science theme concerns the science of volcanoes and other geohazards as well as that of earthquakes.
