1802 Oct 26, 10:55 UTC, 45.8 N 26.6 E, magnitude 7.1. Many buildings largely damaged in Bucuresti, sulphur water flowed from cracks in the ground, houses damaged and walls of churches fissured at Craiova, Iagi, Vidin, Ruse, Chernovtsy, Varna, Brasov, Sibiu, felt at Istanbul. Widely felt in the Balkans and in Ukraina (MMC, PRA, FA, WS), allegedly also in Moscow, Peterburg (Leningrad), Tula, Kaluga, Orel (PAD, MJD). (reference #1099)

1802 Oct 12, magnitude 7.7. This was a large, intermediate-depth earthquake of an estimated magnitude of 7.7 occurring at the Vrancea seismic source, Romania (Constantinescu and Marza, 1989; we adopted focal parameters estimated by them). The earthquake was perceptible at very long distances, from St. Petersburg to the north, to Ithaki island in Ionian Sea to the south, but it was highly destructive in Bucharest (von Hoff, 1841; Mallet, 1855). The very long radius of perceptibility is a common feature of the intermediate-depth earthquakes of Vrancea as well as those of the Hellenic arc and elsewhere. (reference #9391)
