An experiment to track the attack and defense between Ukraine and Russia in real time using a seismometer was successful. Academic attention was focused on the new discovery of understanding the aspects of war and monitoring the war situation through seismometers.
A joint Ukrainian and Dutch research team released an experiment report containing this information on the 7th. The research team, which believed that various explosions occurring on the battlefield can be captured with a seismometer, used the National Information Center’s seismic observatory located regarding 100 km northwest of Kiev, the capital of Ukraine, to test the hypothesis.
The 24 seismometers installed at this observatory were originally used to detect explosions. This is one of the facilities that internationally monitors nuclear testing in accordance with the Comprehensive Nuclear-Test-Ban Treaty (CTBT). As it was located in Ukraine, which is still at war, it was the perfect laboratory to prove the research team’s hypothesis.
The war between Ukraine and Russia lasts over a year and six months. The international community is using various methods to accurately understand the situation. <사진=pixabay>
An official in charge of the experiment said, “Ordinary explosions in battlefields generate seismic signals of magnitude 1 to 2 that cannot be detected by humans,” and added, “Explosions that have occurred in Kiev, Zhytomyr, and Chernihiv since February and November of last year were 1200. “As a result of observing more than one episode using sound waves and seismic waves, we were able to determine the aspects of the battle more precisely than expected,” he said.
The official added, “The data that automatically identified individual attacks in northern Ukraine in almost real time and observed the disputed area where fighting continues using seismometers surprisingly showed accuracy that surpassed images captured by satellites.”
When an earthquake occurs when the Earth’s rock is shifted, transverse waves with complex up-and-down movement patterns are generated. In contrast, an explosion is a compression wave that spreads at a constant pressure in all directions and spreads in a spherical shape. Seismic waves from the explosion propagate hundreds of kilometers forward at a speed of regarding 8 km per second on the ground and regarding 0.34 km per second in the air.
Experimental results have shown that the situation of the war can be determined by detecting various types of explosions that occur on the battlefield with a seismometer. <사진=pixabay>
According to the research team, this method was also able to distinguish seismic acoustic signals related to various attacks such as grenades and rockets. The research team expected that the use of new technology would improve the accuracy of reporting on war and monitor violations of international law committed during war.
An official in charge of the experiment said, “As a result of this study, it was revealed that there were far more explosions and battles in Ukraine than reported by media outlets around the world.” He added, “As there are more than 200 seismic and infrasound observatories around the world, we can utilize them. “We will be able to clearly see the patterns of conflict taking place around the world,” he emphasized.
