Abstract

Venus is home to thousands of volcanic landforms that range in size from less than 5 km in diameter to well over 100 km in diameter, and their extrusive materials comprise ~80% of the surface. With the NASA Magellan SAR (synthetic aperture radar) FMAP (full-resolution radar map) left- and right-look global mosaics at 75 meter-per-pixel (m/px) resolution, we created a global catalog of volcanic edifices on Venus that contains ~85,000 features, ~99% of which are volcanoes <5 km in diameter. Additionally, we developed an automated approach to grouping volcanoes into "shield fields": areas with relatively high spatial concentrations of shield- or dome-like volcanic edifices that are ≤20 km in diameter. This global dataset can be used as a tool to investigate the morphological, spatial, and temporal properties of volcanoes on Venus.
