Volcanoes are one of nature's most powerful and destructive forces experienced on Earth. Lava flows, explosions of ash, molten rock and huge eruption clouds are pictures we relate to of volcanoes destructive power. But why do volcanoes erupt? This booklet identifies different types of volcanoes, and the dangers associated when volcanic materials are ejected in an eruption. It explains the importance of why we should study volcanoes and the effects these eruptions have on the atmosphere and climate. It also identifies where volcanoes are located in Australia. Student activities are included.

At least as early as 1940, it was realised by the Department of the Interior that the reserves of suitable rock (shale or slate) in the pit adjacent to the Canberra Brickworks were limited. A decision was made to find a temporary site to provide sufficient material to supply the brickworks for two years. A site at Deakin, 1700 yards by road east from the existing brickworks was selected and was recommended by Dr. W.G. Woolnough in 1940 as suitable, subject to testing by costeans and pits. A survey of the area in the subdivision of Deakin, Canberra City Area, was then arranged and was made during March and April, 1944, the object being to determine if there were sufficient reserves of suitable material to supply the Canberra brickworks for a period of not less than two years. This report describes the results of this survey.
