Field analysis of two lava flows from the Southern Andes of Chile Volume- and cooling-limited lava flows show different morphologies and dimensions Volume-limited flows can be simulated as Herschel-Bulkley, Bingham or Newtonian fluids with constant temperature Cooling-limited flows are best simulated with the Yield Strength in the Crust regime
