No signs of abnormality detected
Discussing the phenomenon of strong earthquakes appearing in large numbers, Dr. Nguyen Xuan Anh - Director of the Institute of Earth Sciences said that the specialized agency is continuing to monitor and analyze data to assess in more detail, but currently "no signs of abnormality have been detected".
He affirmed: "The occurrence of earthquake stimulation depends on many factors of earthquake and hydrological activities, there needs to be in-depth research to assess, not if there is a lot of rain, there will be an earthquake".
According to him, this phenomenon may be related to excited earthquakes, that is, due to the influence of the water storage process of hydroelectric reservoirs. When water pressure rises, it can impact the broken systems below, releasing energy and causing some earthquakes to occur earlier than the natural law.
Mr. Nguyen Xuan Anh cited that Vietnam has recorded similar phenomena in the area of large hydroelectric reservoirs such as Hoa Binh, Son La, Song Tranh 2 or Kon Plong.
stimulating earthquakes can last for many years
According to the Institute of Earth Sciences, the stimulating soil activity in the Kon Plong area may continue for many years to come, even about 10 years to stabilize again.
However, he reassured that the possibility of an earthquake exceeding 5.5 degrees Richter in the near future is very unlikely. Specialized agencies still maintain a monitoring and warning system and are ready to provide timely information to local authorities and people when there are new developments.
Experts recommend that people in areas likely to be affected should stay calm and avoid spreading unverified information. When there is an earthquake, it is necessary to quickly find a safe shelter, away from the walls, glass, and heavy objects that can fall.
Local authorities and investors of hydroelectric reservoirs are requested to strengthen seismic monitoring, control reservoir water levels, and publicly and regularly disclose transparent information to reassure people.
According to the Center for Earthquake Information and Tsunami Warning (Institute of Earth Sciences), in the past 24 hours, 20 earthquakes have been recorded in the Central Highlands and neighboring areas, including 3 matches with an intensity exceeding 4 degrees Richter and 4 other matches above 3 degrees. Notably, last night alone (October 5), there were 3 quite strong earthquakes.
