The largest tremor hit at 7:20 pm with a depth of approximately 8.1 kilometers, said Nguyen Xuan Anh, director of the Vietnam Earthquake Information and Tsunami Warning Center, under the Institute of Earth Sciences.
Earlier the same day, two smaller tremors of magnitudes 2.6 and 2.7 were recorded at 2:02 pm and 5:20 pm, respectively, in the same district at the same depth.
All three events were categorized as low-risk and caused no reported damage.
The center continues to monitor seismic activity in the region.
In Vietnam, earthquakes with magnitudes between 2.0 and 4.0 are generally classified as weak.
Earthquakes with magnitudes from 2.0 to 3.0 may be felt as very light tremors by some people and pose no risks to infrastructure.
Quakes with magnitudes between 3.0 and 4.0 can cause light shaking and might rattle household objects, but rarely lead to harm.
Globally, over one million quakes of 2.0-3.0 magnitude and more than 100,000 in the 3.0-4.0 range occur each year.
In February this year, seven minor quakes with magnitudes from 3 to 3.5 were recorded in Nam Tra My.
Bac Tra My District also has a history of induced seismic activity.
