2. Taroona on the Move
Simon Stephens (geologist and local resident) is interviewed by Taroona High students Emily Duncombe and Ollie Mackay.
The geology of Taroona shows two different ages and types of rocks. The older, harder rocks of the Alum Cliffs and the hills above Taroona are glacial mudstones on the lower levels with dolerite above. These rocks have eroded from the hills to form unconsolidated sands muds and boulders along the coast. Some of this is still sliding. Landslip monitors in the area measure this movement at about 2-5 millimetres per year.
