Abstract. Using original sources of information is important requirement in historical seismology. Modern technologies make much easier the access to old papers and other, hardly accessible before, archive materials. The new possibilities lead to publications, where already studied historical earthquakes are revised. This publication is among such ones. The main goal is to present newly found macroseismic information on 1802 deep Carpathian earthquake from original sources and assess its magnitude based on this data. Assessment of magnitude using macroseismic field equation specially developed for deep Carpathian earthquakes is characterized by larger error than calculated using equation for crustal earthquakes. But the specially developed equation is better balanced for the whole epicentral distances in near and far zones, in the sense, that the magnitude and its error is practically the same, being calculated separately for near and far zones. Application of macroseismic field for crustal earthquakes leads to significant differences in these assessments.

Keywords: historical earthquakes, macroseismology, macroseismic field equation, deep Carpathian earthquakes, Vrancea region
