**************************************************************** From: Ken Dean <ken.dean@xxxxxxxxxxxxx> **************************************************************** Dear colleagues, We invite everyone who is interested to submit abstracts for the following symposium at the 2008 IAVCEI General Assembly in Reykjavik, Iceland, 18-22 August, 2008. The abstract submission deadline is 1 April 2008. Title: Remote Sensing of Volcanoes: Ground, Air and Space Observations Further information about the conference and abstract submission process can be found at http://www.iavcei2008.hi.is/page/I08-intro. We look forward to a very stimulating, interdisciplinary symposium on this intriguing topic. Conveners: Ken Dean: IAVCEI Remote Sensing Commission Leader, Alaska Volcano Observatory, ken.dean@xxxxxxxxxxxxx <mailto:ken.dean@xxxxxxxxxxxxx> Jon Major: U.S. Geological Survey, Cascades Volcano Observatory (jjmajor@xxxxxxxx <mailto:jjmajor@xxxxxxxx>) Andy Harris: University of Hawai'i, Honolulu, HI 96822, harris@xxxxxxxxxxxxxx <mailto:harris@xxxxxxxxxxxxxx> Mike James: Lancaster University (m.james@xxxxxxxxxxxxxxx <mailto:m.james@xxxxxxxxxxxxxxx>) John Chadwick: University of North Carolina, Charlotte, NC 28223, djchadwi@xxxxxxxx <mailto:djchadwi@xxxxxxxx> Andy Hooper: Nordic Volcanological Centre, University of Iceland (ahooper@xxxxx <mailto:ahooper@xxxxx>) Description: The capabilities of image-based remote sensing have advanced significantly over the past decade, allowing improvements in our ability to detect and analyze surface change, volcanic plumes and drifting volcanic clouds, using a wide range of wavelength data. Detection of thermal anomalies have provided insights into variations in thermal flux and effusion rates, and how they relate to subsurface processes or act as precursory signals to explosive events. Optical, infrared and microwave wavelength data at high spatial resolutions have also provided unique insights into volcanological processes regarding the morphology and composition of deposits, and hazard assessments. InSAR and lidar have become valuable tools for measuring surface deformation. Ground verification of satellite observations has always been problematic due to scaling and wavelength issues. However, the use of digital cameras and video, point-based infrared thermometers and spectrometers, thermal infrared and ultraviolet camera systems, as well as near-infrared, radar and millimetre- and micro-wave scanning systems, have not only helped solve this problem but have provided new understanding of at-vent emission dynamics, plume ascent characteristics and lava flow emplacement processes. The intent of this session is to bring together these divergent components of remote sensing of volcanoes to review and summarize results from investigations and new developments. The session will focus on the following areas of research: - The application of emerging remote sensing technologies and new applications of existing techniques, - The structure, characteristics, movement and modeling of volcanic ash and SO2 clouds, - The relationship between variations in thermal flux and effusion rates to subsurface processes and degassing, - The relationship between surface deposits and eruption chronology, style and processes, - Short and long term deformation patterns and their relationship to eruption style frequency and magnitude, - The dynamics of near-vent processes, - Review papers integrating multi-parameters analyses are particularly welcome. ------------------------------------------------------------------------ Ken Dean IAVCEI Remote Sensing Commission Leader Alaska Volcano Observatory Geophysical Institute University of Alaska Fairbanks ============================================================== To unsubscribe from the volcano list, send the message: signoff volcano to: listserv@xxxxxxx, or write to: volcano-request@xxxxxxxx To contribute to the volcano list, send your message to: volcano@xxxxxxxx Please do not send attachments. ==============================================================
