SummaryWe propose to acquire Terra SAR-X Spotlight mode amplitude imagery over the Volcan de Colima (VdC), Mexico. VdC has recently resumed activity after a 2 year hiatus. Vulcanian explosions began in mid-January 2013 and an overflight in late January indicated that that lava dome growth recommenced a few weeks afterwards. Based on current seismicity it seems that small rockfalls and/or small pyroclastic flows have started to occur. These will result in deposits on the flanks of the volcano. High resolution imagery from Terra SAR-X will be used to document any changes in the summit and the growth of the lava dome. We will use a short time series of images to identify and track changes at the summit and on the flanks of the volcano. These might be craters in the summit formed by explosions or lava flows. In addition, the imagery will be used for mapping of the spatial distribution of rockfall and pyroclastic flow deposits associated with the renewed dome growth. This information will be used by the Universidad de Colima for routine hazard assessments. Our project will run for 3 months during which time we wish to acquire 12 scenes. We will report the findings of the work in international journals e.g.Journal of Volcanology and Geothermal Research and/or Bulletin of Volcanology and at major conferences. The cost of the imagery will funded by a successful NERC urgency grant
