Parametric catalogues locate the epicentre of an earthquake occurred on January 4th, 1802 in various areas: in the wider area around the towns of Rijeka, in Croatia (Karnik, 1971) or Trieste, in Italy (Postpischl, 1985); in southern Slovenia near to the Croatian border (Shebalin et al., 1974) or in the eastern part of Istrian peninsula (Cvijanovic, 1981) (Fig. 1). The parameters assigned to this earthquake by these catalogues are shown in Tab. 1.

Tab. 1 - Main parameters of the 1802 earthquake in the parametric catalogues. Parametric catalogues disagree also upon date and time of the earthquake - Shebalin et al. (1974) and Cvijanovic (1981) date the event on January 3rd - and about epicentral intensity, which ranges from V MCS to VIII MSK. The earthquake catalogue of Slovenia (Ribaric, 1982) does not include this event.
