A Global Catalog of Volcanoes and Volcanic Fields on Venus
Grant/Award Number and Agency
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.
Additionally, we developed an automated approach to grouping volcanoes into volcanic fields, often referred to as "shield fields" on Venus. Volcanic fields are 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.
