Well the biggest pre-quake catastrophe research has to do with the ionosphere anomalies. Japan and Haiti both had very strong signals a few days before their quakes however I know of know correlation between these type of booms and impending doom.
The theory here from the geologists is that Clintonville sits atop a relatively shallow granite line that is under significant pressure due to these minor (1.5 richter) earthquakes which is leading to these loud booms and shaking...
Who knows...maybe its the end.
