Vigorous strombolian eruptions from Nicaragua's Cerro Negro volcano in 1968 produce an ash-rich column above the vent. Strong incandescent lava fountaining can be seen at the base of the column. Steam rises from fumaroles on the righthand side of the cinder cone. Ash and cinders fall from the eruption column at the left.
A time exposure captures a nighttime view of a strombolian explosion in November 1968 from Cerro Negro volcano in Nicaragua. The trajectory of individual incandescent volcanic bombs can be seen radiating from the vent. Still-hot bombs continue to glow after landing on the outer flanks of the cinder cone. The 1968 eruption was one of many from Cerro Negro, Central America's youngest volcano.
Cerro Negro cinder cone in Nicaragua, Central America's youngest volcano, was born in April 1850. It has been one of Nicaragua's most active volcanoes, building up a roughly 250-m-high cinder cone surrounded by a field of fresh lava flows. Cerro Negro is seen here in 1981 from Cerro la Mula on the north, the next in a chain of four cinder cones erupted along a N-S line.
