Devastating pyroclastic flows and surges from the March-April 1982 eruptions turned large areas surrounding the crater into a moonscape devoid of vegetation.  The pyroclastic flows and surges swept radially away from the volcano to distances of about 6 km, devastating an area of about 150 sq km.  This January 1983 aerial photo shows the effect of extensive erosional dissection of these deposits during the previous rainy season.   Photo by Bill Rose, 1983 (Michigan Technological University).
