Earthquake caused boom in N.E. Philly - Philly.com - Certainly strange. The earth rumbles and causes a 'boom.' I suggest we chalk this one up to the government's secret program of weather and land modification. Now, you may ask, why in the Philly area? Well, it is an historical part of our country and less likely to be suspected of experimentation. So, it's the dreaded earthquake machine in action.
