Both earthquakes occurred within the Gorna Oryahovitsa seismic zone, a geologically active region that extends 100 km from east to west and is 75 km wide. This area produces shallow earthquakes and have the potential to generate earthquakes of magnitude 7.0. The largest earthquake in this zone occurred in 1913, measuring 7.0. These earthquake were caused by rupture at the intersection of two nearly east–west striking and a north-northwest–south-southeast striking faults. One of these east–west trending fault was identified as the Pre-Balkan Fault. They involved vertical (dip-slip) movement on these faults. The February earthquake was caused by movement on the north-northwest–south-southeast trending strand while the December earthquake ruptured the Pre-Balkan Fault.Oncescu M. C. Trifu C. I. Hristova T.
