Dimensions of Lunar Volcanoes
In 1981 Dick Pike and Gary Clow published a paper, Revised
Classification of Terrestrial Volcanoes and Catalog of Topographic
Dimensions, With New Results on Edifice Volume (US Geological Survey Open-File Report 81-1038). Because Pike was also
interested in volcanoes on other planets he included measurements for
18 possible lunar and 15 martian volcanoes. Here are the lunar data.
Dimensions were measured from Lunar Orbiter IV and Apollo images and
Lunar Topographic Orthophotomosaics.

Crater Diameter is the diameter of the summit crater. Crater Depth is the depth of the crater. Height is the height of the entire volcano above its surroundings. Volcano Diameter is the diameter of the base of the volcano. Circularity is a measure of the crater's circularity = area of an inscribed circle divided by the area of circumscribed circle; 1 = perfect circle. All measurements in meters, except Circularity. Class: LC = cratered raised cone; LH = dark-halo crater; LD = cratered dome
