DESCRIPTION:Satellite imagery provides a unique window into volcano and ma
 gmatic processes\, providing potentially global measurements of deformatio
 n\, degassing and thermal emissions.  These measurements illuminate stages
  of magmatism spanning from pluton growth\, to landscape formation to the 
 environmental impact of volcanic eruptions.  Satellite radar measurements\
 , in particular\, capture processes associated with the movement of magma 
 in the Earth’s crust and can play a role in forecasting the development 
 of unrest and duration of eruptions.  I will discuss efforts to automate p
 rocessing and analysis\, required by the recent order of magnitude increas
 e in freely available\, systematically acquired satellite imagery. This in
 volves the application of signal processing methods such as source separat
 ion and unsupervised classification\, and is also a powerful tool for dist
 inguishing between superimposed geophysical processes.  My research focuse
 s on how to extract volcanologically useful parameters from satellite imag
 ery\, and I will present case studies of effusion rate estimation\, charac
 terisation of eruption volume from vegetation impacts and the impact of rh
 eology on displacements.\nSpeakers:\nDr Susanna Ebmeier (University of Lee
