Emplacing a Cooling-Limited Rhyolite Lava Flow: Similarities with Basaltic Lava Flows
Accurate forecasts of lava flow length rely on estimates of eruption andmagma properties and, potentially more challengingly, on an understanding of the relative influence of characteristics such as the apparent viscosity, the yield strength of the flow core, or the strength of the lava’s surface crust. For basaltic lavas, the relatively high frequency of eruptions has resulted in numerous oppo...
متن کاملPulsatory andesite lava flow at Bagana Volcano
[1] Using a time series of TerraSAR-X spaceborne radar images we have measured the pulsatory motion of an andesite lava flow over a 14-month period at Bagana Volcano, Papua New Guinea. Between October 2010 and December 2011, lava flowed continuously down the western flank of the volcano forming a 3 km-long blocky lava flow with a channel, levees, overflows and branches. We captured four success...
متن کاملTopographic Variability: Implications for Lava Flow Modeling
Introduction: Glaze et al. [1] and Baloga et al. [2] have both recently indicated the importance of understanding the scale of a lava flow relative to the surrounding topography in extracting inferences about rheologic changes and the interpretation of the style of emplacement. The underlying scientific issue is whether flow emplacement is controlled by the largescale topographic inclination or...
متن کاملLava flow surface roughness and depolarized radar scattering
Surface roughness has a strong controlling influence on radar scattering and other types of remote sensing observations. We compare field measurements of surface topography and dielectric constant for a range of lava flow textures to aircraft multipolarization radar observations at 5.7. 24, and 68 cm (C, L, and P band) wavelengths. The roughness is found to vary with scale in a self-affine (fra...
