<P> The Earth's most historically active cinder cone is Cerro Negro in Nicaragua . It is part of a group of four young cinder cones NW of Las Pilas volcano . Since its initial eruption in 1850, it has erupted more than 20 times, most recently in 1995 and 1999 . </P> <P> Based on satellite images it was suggested that cinder cones might occur on other terrestrial bodies in the solar system too . They were reported on the flanks of Pavonis Mons in Tharsis, in the region of Hydraotes Chaos on the bottom of the Coprates Chasma, or in the volcanic field Ulysses Colles . It is also suggested that domical structures in Marius Hills might represent lunar cinder cones . </P> <P> The size and shape of cinder cones depend on environmental properties as different gravity and / or atmospheric pressure might change the dispersion of ejected scoria particles . For example, cinder cones on Mars seem to be more than two times wider than terrestrial analogues as lower atmospheric pressure and gravity enable wider dispersion of ejected particles over a larger area . Therefore, it seems that erupted amount of material is not sufficient on Mars for the flank slopes to attain the angle of repose and Martian cinder cones seem to be ruled mainly by ballistic distribution and not by material redistribution on flanks as typical on Earth . </P> <P> Some cinder cones are monogenetic--the result of a single, never - to - be-repeated eruption . Parícutin in Mexico, Diamond Head, Koko Head, Punchbowl Crater and some cinder cones on Mauna Kea are monogenetic cinder cones . </P>

When was the last time a cinder cone volcano erupted
