The earthquake originated in the seismically active Vrancea subduction zone beneath the Carpathian arc in Moldavia, a region historically prone to deep-focus intermediate earthquakes generated by the subducting lithospheric slab.
On 26 October 1802, a magnitude 7.9 earthquake struck the Vrancea Mountains of Moldavia. It was felt from Saint Petersburg to the Aegean Sea across more than two million square kilometers, making it the strongest earthquake ever recorded in Romania and one of the most powerful in European history.
In Bucharest, church steeples fell and the Cotroceni Monastery collapsed, with widespread fires from overturned stoves. Bulgarian cities of Ruse, Varna, and Vidin were nearly destroyed. Walls cracked as far north as Moscow, and the main shock was followed by aftershocks including one of magnitude 5.5.
