The first version of this online catalogue had been taken over from a paper published by Mirko Orli\u0107 (Orli\u0107, 2015<\/a>). The second version<\/a>, and all latter versions of the catalogue, have been built by Jadranka \u0160epi\u0107 and Mirko Orli\u0107, by taking into account and scrutinizing the additional information, as it became available. The second version<\/a> was hosted online by the Institute of Oceanography and Fisheries in Split. The third version of the catalogue is presented herein. This version has been built with support of Hrvoje Mihanovi\u0107 (Institute of Oceanography and Fisheries, Split), Iva Me\u0111ugorac and Iva Vrki\u0107 (both from Department of Geophysics, Faculty of Science, University of Zagreb).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The initial information used to build the present catalogue is contained in a couple of papers (Zore-Armanda, 1988; Tabain and Tabain, 1994), as well as in the notes kept by Mirko Orli\u0107 over the last thirty or so years. For all the dates when tsunami-like waves possibly occurred, newspapers were inspected to find articles describing the waves. The first cases considered were from the early 1930s because prior events were usually attributed to the year only and are therefore not easily verified. Two verifications were performed for all of the dates.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The first check was a comparison with an earthquake catalogue (Herak et al., 1996<\/a>, with updates) to ensure that an event in the sea was not preceded by a major earthquake. It turned out that only one of the initial cases \u2013 the event of 15 April 1979 \u2013 was a tsunami, and it was therefore not included in the present catalogue.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The second check was a comparison with sea level records from Bakar (hourly data:\u00a0Me\u0111ugorac et al., 2023<\/a>), the oldest Croatian tide-gauge station, with the aim of detecting a possible storm surge in the Adriatic on the day considered. Because the occurrence of tsunami-like waves of meteorological origin may coincide with the development of storm surge, inexperienced observers may easily confuse the two phenomena. Consequently, all cases when the sea level at Bakar surpassed the mean sea level by 50 cm were marked in the catalogue to indicate that additional data and\/or modelling may be needed to verify their true nature. To each event, an indicator of the quality of available information was assigned. The indicator was selected from a five-grade scale as follows:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

This version of the catalogue is supplemented with analysis of synoptic conditions during all events. For the events that occurred before 1 January 1950, synoptic analyses were done using the NOAA-CIRES-DOE Twentieth Century Reanalysis Project version 3 dataset (<\/span>Slivinski et al., 2019<\/a><\/span><\/span>). For the events that occurred after 1 January 1950, synoptic analyses were done using the ERA5 global reanalysis dataset (<\/span>C3S, 2017<\/a><\/span><\/span>;\u00a0<\/span>Hersbach et al., 2020<\/a>).\u00a0\u00a0<\/span><\/p>

Wherever available,\u00a0<\/span>sea level and air pressure measurements originating from the closest tide gauge\u00a0and meteorological stations are shown. Sea level measurements from Mali Lo\u0161inj, Split-Marjan, Stari Grad and Vela Luka were provided\u00a0by the\u00a0Institute of Oceanography and Fisheries<\/a>\u00a0(Split, Croatia).\u00a0\u00a0Sea level measurements from Bakar were provided by the\u00a0Department of Geophysics<\/a>\u00a0(Faculty of Science, University of Zagreb). Air pressure measurements from Vrboska, Vela Luka and Stari Grad were provided by the\u00a0Institute of Oceanography and Fisheries<\/a>\u00a0(Split, Croatia)<\/span>. Additional air pressure measurements were obtained through\u00a0<\/span>the\u00a0Croatian amateur meteorological network Pljusak<\/a>.<\/a><\/span><\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
