HCMC – Five earthquakes were recorded overnight in Quang Ngai Province, with the strongest reaching magnitude 3.4, according to Vietnam’s earthquake monitoring authorities.
The tremors occurred between 10:43 p.m. on February 22 and 7:04 a.m. on February 23, affecting the communes of Mang Den and Mang But. Magnitudes ranged from 2.8 to 3.4, with focal depths of about 8.1–8.2 kilometers.
The largest quake, measuring 3.4, struck Mang But Commune at 12:14 a.m. on February 23. All events were classified as having a natural disaster risk level of zero, indicating no expected damage.
The Institute of Earth Sciences, through its Earthquake Information and Tsunami Warning Center, said it is continuing to monitor seismic activity in the area.
Experts identified the tremors as induced earthquakes, a type of seismic activity triggered by changes in the local geological environment. They said further earthquakes may occur in the region, but their magnitude is unlikely to exceed 5.5.
Authorities noted that detailed research is needed to better assess seismic activity and risks in the affected area.
