Anyone just feel that? The USGS just reported a 5.9 Earthquake out of Virginia, which is being felt across the region: I’ve been seeing reports from as far away as Indiana, to Toronto, South Carolina and Maine.
From Wikipedia, here’s what an earthquake is:
An earthquake is the result of a sudden release of energy in the Earth’s crust that creates seismic waves. The seismicity or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time.
Essentially, blocks of rock, seperated by faults, are always moving past one another: very slowly. The pressure is continually building and when the pressure overcomes the strength of the rock, it snaps, releasing the energy and causing the tremors that you feel.
Major Earthquakes, like what we saw in Japan, happen because there’s far more energy along far bigger faults. Here in the Northeast, we don’t have quite the same magnitudes, but it’s still a shock when we feel them.
