One local news facility listed that the earthquake measured 6.5 on the Richter magnitude scale, and the USGS listed its seismic moments as 5.6 and 7.9. A research paper of V. I. Ulomov cited this earthquake with magnitude Mw 7.1. Its epicenter was somewhere in the Vrancea Mountains.
The focal mechanism of the earthquake was described as "moderately well controlled", suggesting reverse faulting with some strike-slip motion.
