We end by examining spectral signatures associated with volcanic and erosional processes on the Island of Hawai’i that may aid in forecasting lava flow pathways and deconvolving competing topographic construction and erosion in volcanic landscapes on longer timescales.Īpplegarth LJ, Pinkerton H, James MR, Calvari S (2010) Morphological complexities and hazards during the emplacement of channel-fed `a`ā lava flow fields: a study of the 2001 lower flow field on Etna. We demonstrate that the tendency of a flow to branch or not can be predicted on the basis of spectral characteristics of the underlying surface. The three case studies are generalized with a parameter investigation of lava flow branching on synthetic red-noise topography. Low-pass filter cutoffs in the range of ~ 10–100 m significantly improve the fit between modeled flow and real flow paths, suggesting a sensitivity of lava flow paths to such mesoscale topographic wavelengths. Filtering constrains the height of pre-existing objects that flow overtop as a measure of flow thickness, and aids in identifying divergence of flow pathways from pre-eruptive topography that would result from modification of the substrate by the flow. Spectral filtering of pre-flow digital elevation models allow us to quantify which topographic wavelengths are most important for influencing lava flow pathways. Etna, Mauna Loa, and Ki̅lauea suggests that MULTIFLOW accurately predicts the influence of topography on lava flow paths and morphology. Comparison of MULTIFLOW results with recent flows on Mt. The MUTLIFLOW model includes a multiple flow direction routing algorithm in conjunction with a thresholding function that limits the extent of the flow. To study this problem, we develop a lava flow modeling framework that combines spectral analysis of substrate roughness with a new lava flow model (MULTIFLOW). ![]() ![]() One particular challenge is understanding the interplay between flow pathways and substrate topography that is often rough on a variety of scales (< 1 m to 10 s km).
