Eleven consecutive earthquakes hit Kon Tum Province on November 26.
Data shows that the quakes which measured between 2.7 to 3.8 on the Richter scale occurred in Kon Plong District and people in surrounding areas could feel the shaking.
A local man, Nguyen Van Son, said that he felt the shaking while sleeping at 2 am.
"We saw some furniture shaking as well," Son said. "We knew that earthquakes occurred again as more such quakes have been reported recently. We're worried about our safety."
The earthquakes reported on November 26 were assessed to be small and not causing any risks of natural disasters, the institute said.
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 200 earthquakes occurred in the area in the first seven months of 2024, including 80 in July.
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 recently 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.
