Seismic stations in Ukraine and Romania detected what appears to be an explosion at the Kakhovka Dam on the morning that it failed, Norwegian seismologists tell NPR.
The analysis was done by NORSAR, a Norwegian group that monitors seismic networks throughout Europe. According to their data, the explosion took place on June 6 at 2:54 AM local time in Ukraine. The detection is the first piece of independent evidence that the dam, which held back a reservoir roughly the size of Utah's Great Salt Lake, was blown up, rather than collapsing from strain and mismanagement.
