Volcanic cone

Description

Volcanic cone: a young cinder (scoria) cone on a 1.2 x 1.2 km footprint, 1200.0 x 1200.0 x 174.2 m overall (measured, X x Y x Z). The rim rises 164 m above the ash plain, the crater measures about 359 m rim to rim and 54 m deep, and the cone is about 909 m across at its foot (measured at the break in slope where the flank meets the ash apron): height 0.18 and crater 0.39 of the basal diameter, close to the fresh-cone ratios 0.18 and 0.40 (Porter 1972, Wood 1980). Flanks have a median slope of 31 degrees (cinders rest at about 25-32 degrees). The rim is breached to the south-east; a lobate aa lava flow with pressure ridges issues from the breach, fills the breach valley and ends in a steep front about 516 m from the crater centre, some 61 m out on the plain beyond the foot of the cone. Footprint edge at Z = 0 on all four sides (largest measured deviation under 1 mm); tephra base to -10 m. Painted near-black scoria with reddish oxidised cinders at the rim and in the crater, downslope streaks, dark clinkery lava and a dry steppe plain. Original unbranded model. Overall 1200 x 1200 x 174.2 m. Nominal size: 1200000.00 x 1200000.00 x 174223.08 mm overall. glTF binary (GLB) mesh with materials, modeled in meters at real-world scale. Export to other formats from the viewer. Nominal dimensions for layout, fit checks and visualization; they do not establish a manufacturing tolerance class, load rating or standards certification. Original Innerscene model, released CC0.
