<P> Cinder cones are commonly found on the flanks of shield volcanoes, stratovolcanoes, and calderas . For example, geologists have identified nearly 100 cinder cones on the flanks of Mauna Kea, a shield volcano located on the island of Hawaii . These cones are also referred to as' scoria cones' and' cinder and spatter cones .' </P> <P> The most famous cinder cone, Paricutin, grew out of a corn field in Mexico in 1943 from a new vent . Eruptions continued for nine years, built the cone to a height of 424 meters, and produced lava flows that covered 25 km2 . </P> <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>
