IG- EPN /STREVA InSAR Workshop Quito, June 19th – 20th, 2013 Wednesday 19th Introduction to InSAR - Juliet Biggs (20 minutes) General introduction. What is InSAR? Brief history of InSAR. Primary applications (Volcanoes, EQ, landslides, anthropogenic subs, flooding, deforestation etc.) . Data availability & satellite missions. InSAR for measuring volcano deformation – Susanna Ebmeier (20 minutes) Overview of global measurements of InSAR volcano deformation made to date. What volcanic processes are detectable with InSAR? Description of examples of magmatic deformation (co-eruptive and not related to eruption) and non-magmatic deformation. Brief description of trends in global dataset. IG-EPN talk on Geodetic measurements in Ecuador – Patricia Mothes (20 minutes) [Break] Other applications of radar – Geoff Wadge (1 hr) Ground-based radar systems. Ground-based InSAR, topographic change, rockfall detection, ash monitoring. Satellite radar intensity principles. Intensity change difference monitoring of domes, lava flows and pyroclastic flows. Constructing and interpreting interferograms 1 – Cyril Muller (30 minutes) The general principles of interferometry and how interferograms are constructed, including a runthrough of processing steps as for roipac with illustrations. Constructing and interpreting interferograms 2 – Susanna Ebmeier (30 minutes) Phase contributions to interferograms (deformation, orbital artefacts, dem artefacts, atmospheric artefacts etc.) Finish at 18.00 Thursday 20th Practical session: understanding and modelling interferograms (2 hrs) Introduced by Juliet Biggs, requires access to computers with Matlab. One between 2 or 3. As for CR workshop. Analysing interferograms 1 – Cyril Muller (30 minutes) Analysis of interferograms (stacking, network corrections, resolving components of motion and PS InSAR) Analysing interferograms 2 Juliet Biggs (30 minutes) Modelling volcano deformation (Other approaches to modelling deformation and challenges for interpreting volcano deformation data) [Lunch] Deformation at Reventador – Geoff Wadge (30 minutes) Comparing InSAR to ground-based measurements at Tunguruhua – Cyril Müller (30 minutes) Multiparametric trends in the 14 year eruption process of Tungurahua-Gorki Ruiz (30 minutes) Arc-scale survey: Ecuador 2007-2010 – Susanna Ebmeier (30 minutes) [Break] Discussion of targets for InSAR measurement in Ecuador and future collaboration – Everyone (1 hr) Lead by Juliet & Geoff Friday 21st Installing software and processing interferograms (Susi, Cyril & anyone from IG-EPN with a particular interest)
