From: Probabilistic approach to modeling lava flow inundation: a lava flow hazard assessment for a nuclear facility in Armenia

Parameter = Value Explanation
Inputs  
DEM_SOUTH = 4441 N, S, E, W
DEM_NORTH = 4482 boundaries
DEM_WEST = 408 of the DEM
DEM_EAST = 448  
DEM_SPACING = 0.1 DEM grid spacing (km)
DEM_FILE = file (ASCII format) rows of elevation values (masl)
MIN_RESIDUAL = 1 Map to observed flow thicknesses (m):
MAX_RESIDUAL = 4 1 = 6, 2 = 7, 3 = 8, 4 = 9,
  (lower value = lower lava viscosity)
ERUPTED_LAVA = 1e6 Volume of lava distributed
  per iteration or pulse (m3)
MIN_TOTAL_LAVA = 1 Map to observed flow volumes (km3):
MAX_TOTAL_LAVA = 3 1 = 5 × 108 2 = 5.3 × 108, 3 = 8.7 × 108
FLOWS = 1 Number of lava flows to simulate per run
RUNS = 1000 Number of lava flow runs
AOI_WEST = 426.0 Area of interest
AOI_EAST = 428.2  
AOI_SOUTH = 4447.8  
AOI_NORTH = 4449.0  
SPATIAL_DENSITY_FILE = file X Y Z format, grid of spatial density
  values for the potential of volcanism
SPATIAL_DENSITY_SPACING=.1 spacing of spatial density grid (km)
  1. Configuration file for simulated lava flows from the flanks of Aragats volcano. The format of this ASCII file is parameter = value. The shown values reflect the range of values used for the lava flow simulation for hazard assessment from a flank eruption on Aragats.
