There were no immediate reports of damage, but residents told local broadcaster La Nueva Radio Ya that strong tremors were felt in the capital, Managua.
Meanwhile, the USGS said there was a low likelihood of casualties and damage from the tremor.
However, the agency noted that there are structures in the region that are vulnerable to earthquakes.
Earthquakes occur sporadically in Nicaragua.
In 2014, a 6.2 earthquake in western Nicaragua killed at least one person and injured 33 others.
In 1972, an earthquake of the same magnitude hit 48km (30 miles) north of the capital Managua, killing at least 5,000 people and leaving thousands homeless.
