The Richter scale is calculated as the logarithm to base 10 of the amplitude of the strongest wave of the quake.  The damage in Chile is immense – hundreds killed and 1.5 million left homeless – but the effects are less severe than they would have been had Chile not been prepared. The most intense earthquake in history occurred in Chile in 1960 – 9.5 on the Richter scale – and this killed 2,000 people. Indeed the tsunami induced by that quake induced 25 metre high waves which battered Chile and sites 10,000 kilometres away. The Chilians have consequently set high building standards in order to accommodate anticipated shocks – much of the damage will be concentrated in buildings not covered by such regulation.

I’d got back from Canberra last night about 8-30pm.  It had been a long day and I was wearily sitting in my office at home in the north of Melbourne when, at around 9-00pm, I heard what sounded like a motor outside the window – weird enough for me to stop and think ‘What is that?’. Then the window frame itself started shuddering for 10 seconds or so.  It was an earthquake of magnitude 4.6 – the second I can recall experiencing in Melbourne.
