The epicenter of the 5.8-magnitude earthquake was in Virginia, but it shook much of the East Coast from Georgia to Canada. Scientists said it was the largest quake on the East Coast since World War II. No serious injuries were reported, but cracks appeared in the Washington Monument and the National Cathedral. The epicenter of the earthquake was located just 10 miles from a nuclear power plant that has lacked seismographs since the 1990s. The North Anna Power Station lost off-site power and was using diesel generators to maintain cooling operations at its two nuclear reactors following the quake. The facility, which was built on a fault line, is only designed to withstand an earthquake up to a magnitude of 6.1. Yesterday’s quake registered a 5.8. All of the plant’s seismographs were removed in the 1990s due to budget cuts. Federal officials said a total of six nuclear plants from North Carolina to Michigan are under increased scrutiny after the earthquake. Meanwhile, earthquakes have also been reported in Colorado and California over the past 24 hours.
