TanDEM-X Time Series Analysis Reveals Lava Flow Volume and Effusion Rates of the 2012-2013 Tolbachik, Kamchatka Fissure Eruption

Julia Kubanek, Malte Westerhaus, Bernhard Heck
2017 Journal of Geophysical Research - Solid Earth  
We developed a processing scheme for generation of 18 DEMs from TanDEM-X imagery that relies on the generation of a preeruption DEM which is used to process the syneruption and posteruption data pairs.  ...  Assessing eruption volumes is one of the major challenges in volcano research but provides valuable insights into the dynamics of an eruption and the associated hazard.  ...  The modeling performed by using the Tolbachik lava flows as input again corroborated the final lava flow volume calculated within this study and shows the stand-alone applicability of TanDEM-X to study  ...
