Western Australia has had a regular history of earthquakes throughout its geological history. During European occupation — and since the science of seismology has developed — some earthquakes are better known due to their impact on urban areas. The Meckering earthquake of October 1968 is considered the main impacting earthquake on Western Australia of the twentieth century. ==Recording== Prior to scientific equipment being utilised to record earthquakes, newspaper reports appear to be the main source of historical information.〔Everingham, I.B. and Tilbury, L.
