<P> Strombolian eruptions eject volcanic bombs and lapilli fragments that travel in parabolic paths before landing around their source vent . The steady accumulation of small fragments builds cinder cones composed completely of basaltic pyroclasts . This form of accumulation tends to result in well - ordered rings of tephra . </P> <P> Strombolian eruptions are similar to Hawaiian eruptions, but there are differences . Strombolian eruptions are noisier, produce no sustained eruptive columns, do not produce some volcanic products associated with Hawaiian volcanism (specifically Pele's tears and Pele's hair), and produce fewer molten lava flows (although the eruptive material does tend to form small rivulets). </P> <P> Volcanoes known to have Strombolian activity include: </P> <Ul> <Li> Parícutin, Mexico, which erupted from a fissure in a cornfield in 1943 . Two years into its life, pyroclastic activity began to wane, and the outpouring of lava from its base became its primary mode of activity . Eruptions ceased in 1952, and the final height was 424 m (1,391 ft). This was the first time that scientists are able to observe the complete life cycle of a volcano . </Li> <Li> Mount Etna, Italy, which has displayed Strombolian activity in recent eruptions, for example in 1981, 1999, 2002--2003, and 2009 . </Li> <Li> Mount Erebus in Antarctica, the southernmost active volcano in the world, having been observed erupting since 1972 . Eruptive activity at Erebus consists of frequent Strombolian activity . </Li> <Li> Stromboli itself . The namesake of the mild explosive activity that it possesses has been active throughout historical time; essentially continuous Strombolian eruptions, occasionally accompanied by lava flows, have been recorded at Stromboli for more than a millennium . </Li> </Ul>
