An Interesting Way to Look at Earthquake Frequency

This summary of global earthquake activity adds a couple of dimensions I have not seen before. First, the magnitude of the earthquake is indicated by the volume of the sound played (as well as by the size of the circle.) Second, the cumulative total number of earthquakes is plotted across the screen. Look and listen for the 9.0 Honshu earthquake around 1 minute 50 seconds.(Source Blick's Picks)
