Redirecting lava flows
WebThe basaltic lava flows of Mount Lassen and the Hawaiian Islands have three distinguishable surface textures. Aa lava has a texture resembling that of broken scoria, block lava has broken cleanly after congealing, and pahoehoe has a relatively smooth surface. Aa lava with channels is usually found on the steeper slopes, while WebThis is rarely true at the steep margins of a’ā flows. When lava flows into topographic depressions, deep ponds of lava have been observed to form (Pedersen et al., 2024), whose behavior cannot be satisfactorily captured by the steepest-descent method. The most complete lava flow models simulate three-dimensional viscous flow with spatially and
