Philly quake - Murphy's seismograph law?

Our seismograph is down due to a bad hard drive.

So of course there is an earthquake in the area.

Small earthquake shakes NJ, Delaware, Pa.

NEWPORT, Del. - The National Earthquake Center says a small earthquake felt Wednesday in the Wilmington, Del. area had its epicenter in southern New Jersey.

The center says the earthquake measured 2.8 on the Richter scale, up from an earlier estimate of 2.7. That's big enough to feel, but too small to cause much damage.

The epicenter was near Mannington Township, near the Delaware River.

Salem County deputy administrator Robin Weinstein says he felt shaking in his emergency management office soon after the quake began at 9:46 a.m. No injuries or damage were reported.

A spokesman for PSE&G Nuclear, which operates three nuclear power plants in Salem County, says the quake was too minor to register on the plant's monitoring devices."
