Radially Patterned Intermediate Volcano
Shield volcano with petal-like (digitate) radar-bright lava flows radiating from the center, with a diameter of 20–100 km (Head et al. 1992).
Anemone; Anemone-type volcano
These features are defined by their radar backscatter patterns and have been interpreted as structures with an extremely low topographic profile. Digitate lavas of strikingly uniform length and width emanating radially from the vent are radar dark near the vent and brighten toward the tips (Head et al. 1992). These petal-like narrow lava flows radiate from a craterlike or elongated fissure-like source; the fissure-type vents are often aligned with regional linear faulting patterns (Head et al. 1992).
Mean diameter of 39.9 km (min. 20 km, max. 90 km), mean height of 370 m (min. 200 m, max. 580 m), and a mean aspect ratio of 189 (min. 116, max. 330) (White 2010).
