Link to the Event sheet (pdf) of most of the revised events can be found by clicking on "Dataset by Prachař, Pazdírková 2022" in the individual event window.

The CZ Historical Earthquake Database was created as a part of the Sigma-2 project, one of the objectives of which being to compile a catalogue of earthquakes with a focus on the territory of the Czech Republic and its immediate surroundings. The catalogues Kárník et al. 1958, Kárník et al. 1981 and some others (see below) were utilized as basic input sources. Many other catalogues and publications were used, too. Newly discovered earthquakes, that were not listed in any catalogue so far, were also processed.

A text file (Event sheet) containing a citation from the Kárnik catalogue or another source was created for each event whose focus could potentially be placed in the area of interest. Basal resources of Kárník et al. 1958 and/or other sources were traced and their exact citations were added to the Event sheet, including their transcription and translation. Other records relating to the event were searched for in other catalogues, scientific articles, chronicles, municipal registers, parish registers, letters, questionnaires or newspapers and then added to the Event sheet.

All pieces of information obtained were analysed in detail. In case of positive assessment (earthquake) a list of observation points (MDPs - macroseismic data points) was compiled and the earthquake parameters determined, if possible.

Some events were found not to be earthquakes or could not be evaluated:

• / DOUBT : cannot be evaluated because primary reports were not found or were insufficient or questionable.
• / FAKE : a false earthquake, either due to erroneous dating or location, or it was caused another natural phenomenon - e.g. landslide, meteorite, windstorm.
• / DIST : confusion of a local earthquake with the observation of a distant earthquake.

        Not done yet:

The revision of some earthquakes has not been completed yet.
A large part of earthquakes occurring in the swarm area of western Bohemia and Vogtland have not been processed yet and their parameters were taken mostly from the Leydecker 2016 catalogue.
The database does not contain Czech observations of strong earthquakes that originated outside the Bohemian Massif as well.
