Pyroclastic density current volume estimation after the 2010 Merapi volcano eruption using X-band SAR

Volcano-tectonic control of Merapi's lava dome splitting: The November 2013 fracture observed from high resolution TerraSAR-X data

“…Near summit structural discontinuities have been described based on geodetic data (Beauducel et al, 2006). In 2006, following a deadly earthquake just 40 km to the south of the summit (Walter et al, 2007(Walter et al, , 2008, Merapi tripled its volcanic activity and the direction of pyroclastic flows changed from western direction to southern direction through the Gendol valley abruptly (Bignami et al, 2013;Ratdomopurbo et al, 2013). In the case of the November 2013 activity, it cannot be concluded with certainty that the explosion was triggered by the earthquake 15 min before; a possible causal relationship remains to be studied.…”

Mapping the 2010 Merapi pyroclastic deposits using dual-polarization Synthetic Aperture Radar (SAR) data

“…Remote sensing has been largely applied to characterize the deposits of the 2010 Merapi eruption, either based on optical data Komorowski et al, 2013;Solikhin et al, in revision) or SAR images using X-band (Bignami et al, 2013) or L-band (Saepuloh et al, 2013;Yulianto, Sofan, Khomarudin, & Haidar, 2013). As SAR images can be used to track lava extrusion and dome growth at highly explosive andesitic volcanoes, they were essential for managing the 2010 eruptive crisis of Merapi (Pallister et al, 2013).…”

High‐resolution digital elevation model from tri‐stereo Pleiades‐1 satellite imagery for lava flow volume estimates at Fogo Volcano

“…Precise, quantitative analyses of topographic changes associated with volcanic eruptions provide the means to infer key parameters for the assessment of hazards associated with the volcanic activity (e.g., magma discharge rate in effusive events) [Pinel et al, 2014]. The topographic approach, which constrains the changes in topography by differentiating preeruptive, coeruptive, and posteruptive digital elevation models (DEMs) [Stevens et al, 1999], can nowadays be considered the most suitable method to accurately quantify the volume of new volcanic deposits, especially when data are acquired by spaceborne Earth Observation (EO) platforms [e.g., Lu et al, 2003;Rowland et al, 2003;Bignami et al, 2013;Poland, 2014;Albino et al, 2015;Kubanek et al, 2015;Martino et al, 2015]. These data sets provide densely spaced measurements of heights at relatively high temporal frequency (hours to days, if combined) and meter level vertical accuracy, without the need for direct field measurements.…”
