(Reuters) – The strong earthquake that rattled the eastern United States on Tuesday was highly unusual in its severity, though it was centered in a part of Virginia known for smaller quakes, seismologists said.

The initial earthquake, which registered a magnitude of 5.9 just before 2 p.m. EDT, was felt from the Carolinas to New England.

“One of this size is highly unusual,” said Karen Fisher, a professor of seismology at Brown University and president-elect of the seismology section at the American Geophysical Union. “This is the largest earthquake by far that I am aware of occurring there in recent history.”

The quake’s epicenter in central Virginia is in an area the U.S. Geological Survey calls the Central Virginia Seismic Zone, Fisher said by phone from Providence, Rhode Island.

The U.S. Geological Survey has posted this map of the 5.9-magnitude earthquake that hit central Virginia just before 2 p.m. today, sending tremors up and down the East Coast.

The yellow glow represents the area where potential damage is deemed “light” and perceived shaking is “moderate.”

The quake’s frequency hit the geology of the region just right, like a tuning fork, and reverberated outward, said Alexander Gates, the chairman of earth and environmental sciences at Rutgers-Newark, and an earthquake expert. But there’s no likely danger for aftershocks of the Virginia quake, which will be significantly more minor, he said.

“That was pretty good, huh? I was impressed,” Gates said. “You don’t get earthquakes like that so often on the East Coast.”

Though small earthquakes occur in New Jersey all the time, earthquake experts said today’s shaking was highly unusual.

“It’s probably the largest one people have felt in New Jersey in decades,” Read more…
