cinder cone volcanoes have explosive eruptions.
what type of eruption does cinder cone volcanoes have?
explosive
although paleomagnetic evidence can be used to rule out the 1850s as the age of cinder cone, it does not provide an actual age for its eruption. by measuring levels of carbon-14 in samples of wood from trees killed by the eruption of cinder cone, usgs scientists obtained a radiocarbon date for the eruption of between 1630 and 1670. such a date is also consistent with the remnant magnetization preserved in the lava flows. the series of eruptions that produced the volcanic deposits at cinder cone were complex and are by no means completely understood. however, the new studies done by usgs scientists refute the purported accounts of an eruption in the early 1850s and confirm diller's (1891, 1893) interpretation that cinder cone erupted in the latter half of the 17th century. they also suggest that the 1666 tree-ring date proposed by finch (1937) for his "second" explosive eruption at cinder cone might actually date the entire eruptive sequence.
cinder cone and the fantastic lava beds
cinder cone is a -high volcanic cone of loose scoria. the youngest mafic volcano in the lassen volcanic center, it is surrounded by unvegetated block lava and has concentric craters at its summit, which have diameters of and . cinder cone is comprised by five basaltic andesite and andesite lava flows, and it also has two cinder cone volcanoes, with two scoria cones, the first of which was mostly destroyed by lava flows from its base. cinder cone volcanoes are typically monogenetic, meaning that they only undergo one eruptive period before ceasing activity forever. these eruptions often consist of the ejection of tephra, though they may also generate lava flows, which often originate from vents near the base rather than the summit of the volcanic edifice.
