Another Earthquake

A quick post tonight: this latest earthquake has shaken us all here in Canterbury. The 6.3 shock was less in magnitude than the 4 September earthquake, but far more devasting, due to the proximity to central Christchurch during a weekday lunchtime.  The death toll has reached 65, rescue workers will continue to search the wreckage throughout the night and city dwellers are homeless.  My home, my family (and the Skudder house) are safe and sound. Why do I feel so much more vulnerable this time round?
