Background:The gold mineralization in the area prompted one of the world's last great gold rushes, beginning in 1922. Gold mineralization is related to the hydrothermal explosion craters and the formation of dacitic and andesitic lava dome extrusion. Gas emission and a landslide from Koranga in May 1967 were considered to have had either a non-volcanic or hydrothermal-eruption origin.Source: Smithsonian / GVP volcano information |
