23 August 2011


I just experienced the second earthquake of my life.  This one was bigger than the one I felt about seven years ago.  Click here for a link to the United States Geological Survey data of the Virginia earthquake of 23 August 2011.  The earthquake's magnitude was 5.9.  Just like the logarithmic scale I mentioned for sound loudness in my last post, earthquake magnitudes are also on a logarithmic scale.
