An ash-rich eruption plume rises above Cerro Negro volcano in April 1992. Violent strombolian eruptions during 9-14 April produced heavy ashfall that caused extensive damage to buildings and croplands and forced the evacuation of 28,000 people. Ash clouds reached heights of 7-7.5 km and were distributed to several hundred km distance. The strong explosive eruption enlarged the summit crater to 370 m width.
