According to the Earthquake and Tsunami Warning Centre, the first earthquake happened at 2.16 am with a magnitude of 3.2 on the Richter scale in Kon Tum's Kon Plong District.
And another quake hit Quang Nam's Nam Tra My District at 3.15 am with a magnitude of 3.8 on the Richter scale and at a depth of about 8.10 km.
Earlier on January 24, two quakes were also reported in Kon Plong and one in Nam Tra My.
Earthquakes have been occurring frequently and continuously in Kon Plong since 2021. Recently, their frequency and magnitude have been on the rise.
Statistics from Kon Plong District authorities showed that over 440 earthquakes occurred in the area in 2024.
Explaining the situation, the institute said that the consecutive tremors in Kon Plong are considered induced earthquakes caused by the construction of reservoirs and hydropower dams.
The institute predicted that earthquakes would continue in the coming time and were unlikely to be greater than 5.5.
Chairman of the Kon Tum Provincial People's Committee, Le Ngoc Tuan, has asked for close monitoring of all the tremors and instructed the owners of hydroelectric reservoirs in the area and local people to ensure safety.
The Institute of Geophysics has deployed 11 monitoring stations in Kon Tum to conduct in-depth research and evaluate earthquakes in the locality.
