In which on February 22, there were 3 earthquakes in Mang Den commune; on February 23, there were 4 earthquakes in Mang But and Mang Den communes.

Earthquakes in this area are identified by experts from the Earthquake Information and Tsunami Warning Center as induced earthquakes. induced earthquakes occur cyclically, closely related to the water storage activities of reservoirs. There are periods when earthquakes operate weakly, and periods when earthquakes occur frequently. It is forecasted that this area will continue to have earthquakes, but the magnitude is unlikely to exceed 5.5.
From 2021 to now, this area has recorded hundreds of earthquakes. Previously, the area belonged to Kon Plong district, Kon Tum province (now Quang Ngai province). The largest earthquake was recorded on July 28, 2024 with a magnitude of 5.0.
According to the Earthquake and Tsunami Warning Center, from the beginning of the year to now, the whole country has recorded 24 earthquakes with magnitudes M>= 2. 5. In addition to induced earthquakes in Quang Ngai, some other provinces/cities in our country also experienced small earthquakes in Dien Bien, Lang Son, and Son La.
