Rio de Janeiro Governor Luiz Fernando Pezao admitted the state's security had failed and asked for federal help, according to local media.
The tremor did not directly cause fatalities, but damaged dozens of buildings and knocked out power for a million people, authorities said.
Its epicenter was about 140 miles southeast of the origin of the September 19 natural disaster and 275 miles northwest of the origin of a magnitude 8.1 quake that struck on September 7, killing almost 100 people in Oaxaca and the neighboring state of Chiapas. There were no immediate reports of deaths from the quake, which struck at 5:39 p.m.
Many residents, still shaken from the September 19 natural disaster that killed more than 360 people, lingered in the streets instead of returning to their office buildings and homes.
There were no immediate reports of damage or casualties, the head of the local disaster relief agency, Luis Felipe Puente, said.
USGS seismologist Paul Earle said Friday's quake appeared to be a separate tremor, rather than an aftershock of a September 8 natural disaster also centered in Oaxaca, which registered a magnitude of 8.2.
Later, a magnitude 5.8 aftershock hit Oaxaca again.
Mexico, which is located on the Pacific Ring of Fire, has suffered numerous serious earthquakes over the years, with at least 10,000 killed in 1985 when a huge quake struck Mexico City.
