BACKGROUND: A 5.9 magnitude earthquake that originated in Virginia was felt in Pottstown early this afternoon, according to AccuWeather.com Senior Meteorologist Mike Pigott.
The quake centered around the towns Mineral and Louisa, Va., he said.
Pigott said Pottstown felt tremors from the quake, but it's difficult to define the degree of the shakes.
"You can't really measure that," he said.
The quake is likely to deliver more action, he said.
"With an earthquake as large as this one, it's likely there will be ... aftershocks," he said.
Other areas of the country are also dealing with the quake's aftermath.
