Continued earthquakes in Kon Tum caused by hydroelectric projects | National
Accordingly, under the leadership of Deputy Prime Minister Le Van Thanh, on April 19, the technical delegation consisting of experts and scientists trained by Institute of Geophysics, Vietnam Academy of Science and Technology, organized field trips to assess seismic activity in the area. of Kon Plong district in Kon Tum province and its surroundings.
Earthquakes from March 2021 to April 2022 in Kon Plong district, Kon Tum province and nearby areas caused the highest vibration of grade 5 which is not severe enough.
Initially, experts and scientists said that the earthquakes in Kon Plong district were seismic excitations caused by the water reservoir of the hydroelectric project. However, to confirm the causes of earthquakes and have a basis for predicting the trend and intensity of earthquakes in the future to assess the possibility of damage to civil engineering works and hydropower plants, there is a need for detailed surveys, observations and studies of tectonic geology and seismic regimes in and around Kon Tum.
The results of previous research on the seismic regime and seismic activity in Kon Tum and the surrounding area were not detailed enough to be able to assess the cause and the level of danger of earthquakes for civil structures and hydroelectric power plants. At the same time, there are no detailed studies of seismic excitations in the region. A detailed study is therefore necessary to identify the cause and the level of the seismic hazard and to propose suitable intervention solutions. In addition, there is a need for close coordination of ministries, sectors, localities and hydropower management and operation units in the area.
At the same time, it is necessary to spread and guide earthquake response skills to authorities and people in Kon Tum province and surrounding areas.
