Based on a database of over 2000 small volcanoes, it is estimated there are approximately 500,000 identifiable small volcanic edifices on Venus. Of those, 58 percent are classified as shield-shaped, 20 percent are conical-shaped, and 20 percent are domical-shaped. The size frequency distribution of small edifices is comparable to a sample of 51 terrestrial seamounts along the Izu-Bonin Arc in the Northern Philippine-Sea Plate. The average height-to-diameter ratio of typical submarine volcanoes is similar to that of Venusian volcanoes. A majority of small volcanoes occur between 6051.5 and 6053 km planetary radius. A sample of over 3800 small edifices showed a mean diameter of 2.57 km; 41 percent showed diameters of 2-3.5 km. The same is true of a sample of 200 terrestrial submarine volcanoes on the East-Pacific Rise. Except for one cone-shaped volcano, this study measured shields designated S2; they are roughly circular with low inclination aprons, steep margins and a flat-top. This study analyzed the basal diameter, height, and height-to-diameter ratio of five small Venusian volcanoes (below 20 km diameter). The edifices studied include four shield-shaped and one conical-shaped. All are located between 49 S and 50 S latitude and 345 E and 360 E longitude. The range of diameters in our study was 4-9 km. The average diameter was 5.8 km.
