Geoff Hibbs May 4‚ 2012 Primary Succession & Species Diversity of Flora on Mount St. Helens‚ 32 Years PostEruption On May 18 1980‚ Mount St. Helens‚ a stratovolcano in western Washington‚ erupted. The eruption scoured the slopes of the volcano removing vegetation and soil from the vicinity of the mountain. 32 years after the eruption‚ vegetation has returned to the mountain.

stations. The Colombian volcano‚ Nevado del Ruiz‚ came to life in late 1984 with small-scale activity. Volcanologists from the US knew the danger a major eruption could pose to the surrounding area‚ but were unable to predict when the major event would take place because of a lack of resources. Small-scale volcanic activity continued for several months and people were not prepared to evacuate their homes on the basis of this threat. MEDC can greatly reduce the hazards of a volcano in lots of ways. These
