RICHMOND, VA (WTVR) – Geologists say aftershocks will likely continue after Tuesday's strong earthquake centered near Mineral, Virginia shook the state and the East Coast.
The U.S. Geological Survey says 5.8 magnitude earthquake took place at 1:51 p.m. near Louisa County. Two aftershocks of 2.8 and 2.2 magnitudes were also recorded later in the afternoon at 2:46 p.m. and 3:20 p.m., respectively. Another 4.2 magnitude aftershock took place at 8:04 p.m.  The fourth confirmed aftershock occurred about 40 miles northwest of Richmond at 12:45 a.m. Wednesday with a magnitude of 3.4.
William and Mary Geologist Chuck Bailey told CBS 6 News that Tuesday's earthquake, which was the largest registered in the state since 1897, will be known as the "big one." 
In fact, Bailey says people from as far away as Toronto and Atlanta felt the vibrations since the quake took place at such a shallow depth.
Bailey says aftershocks will continue, but that they will likely continue to be small.
However, he says folks near the epicenter in Mineral, will feel the aftershocks. The farther out from the epicenter, the less likely folks will feel the shaking.
Additionally, Earthquake Information Center Geophysicist Amy Vaughan says so far the number of aftershocks has been low.
Vaughan told the Associated Press that it's likely there will be some more aftershocks for days, if not weeks.

A strong but deep earthquake shook a sparsely populated northern jungle region on Wednesday near Brazil's border. There were no reports of damage or injuries.
The quake had a magnitude of 7.0 and was centered 50 miles north of the jungle city of Pucallpa, said Peru's Geophysical Institute and the U.S. Geological Survey.
The temblor shook office buildings in Peru's capital, Lima, about 370 miles away, witnesses said.
In Pucallpa, buildings shook, trees swayed, and people headed out into the street. The agencies said the quake struck at 12:46 p.m. local time (1:46 p.m. EDT) and was centered 90 miles underground. The deeper the quake, the less it is likely to cause damage.
Local media said there were no immediate reports of injuries or damage in central parts of the Andean nation.
Pucallpa is a regional capital and commercial center of about 200,000 population in a sparsely populated region in central-eastern Peru close to the Brazilian border.

PUCALLPA, PERU (BNO NEWS) -- A powerful but deep earthquake struck the Amazon in northern Peru on Wednesday afternoon, seismologists said, injuring several people.
The 7.0-magnitude earthquake at 12.46 p.m. local time (1746 GMT) was centered about 44 kilometers (27 miles) east of Contamana, a town in the Loreto Region in northeastern Peru. It struck about 149 kilometers (92 miles) deep, making it a fairly deep earthquake, according to the Geophysical Institute of Peru.
The United States Geological Survey (USGS), which also measured the earthquake at 7.0 on the Richter scale, estimated that some 40,000 people may have felt strong shaking, while 572,000 people may have felt moderate shaking. Another 2 million people could have felt light shaking.
