The explosion at the Kakhovka dam in southern Ukraine on Tuesday night was detected by regional seismic stations, said a Norwegian seismic research institute on Wednesday.
Data from regional seismic stations showed clear signals on June 6 at 2:54 a.m. local time (0054 GMT), NORSAR institute said in a statement, adding that the time and location of the signals “coincide with reports in the media about the collapse of the Kakhovka dam.”
“The magnitude estimate is between 1 and 2,” it added.
Early this week, an emergency was declared on both sides of the Kakhovka dam in southern Ukraine's Kherson region after it burst – one side is controlled by Russia and the other by Ukraine.
Russia and Ukraine traded blame over the blast, which destroyed part of the dam that supplied water to the Zaporizhzhia nuclear plant and Crimea, which was illegally annexed by Russia in 2014.
