The large expenditure of energy implied by the total intensity 

 of the series of earthquakes suggests at least a possibility of a very 

 appi-eciable amount of movement of the land-mass of Tasmania 

 and S.E. Australia, either upwards or downwards. One does not 

 like to think of mother earth wasting so much of her strength for 

 nothing.
