Date of the event: year, month, day, hour, minute and seconds indicating the initiation time of the event as deduced by the sources. For earthquake- induced tsunamis it corresponds to the earthquake origin time.
Region: in the EM area seven tsunamigenic regions were identified: NW (Norwegian Sea), NS (North Sea), AT (Atlantic Ocean), M3 (Western Mediterranean), M2 (Central Mediterranean), M1 (Eastern Mediterranean), BS (Black Sea).
Subregion: inside each region, several subregions were identified. They are the geographic regions where the tsunamigenic event originated.
Reliability: is a parameter indicating the quality of the data. For each event this parameter was assigned based on the trustworthiness of the information related to the generating cause, the tsunami description accuracy and also on the availability of coeval bibliographical sources. It ranges from 0 to 4: 0= very improbable tsunami; 1= improbable tsunami; 2= questionable tsunami; 3= probable tsunami; 4= definite tsunami.
Cause: a two-letters code specifying the cause of the tsunami. When the tsunami is directly or indirectly determined by an earthquake, the letter E is used: ER (submarine earthquake), EA (earthquake in land), EL (earthquake landslide -when the earthquake triggered a landslide), ES (earthquake marine slide - when the earthquake triggered a submarine slide). Analogously, letter V is used when the tsunami is directly or indirectly related to volcanic activity: VO (submarine eruption), VA (volcano associated – when the volcano is close to the coast), VL (volcanic landslide – subaerial avalanches on the volcano flanks), VS (volcanic marine slide – submarine avalanches on the volcano flanks). When the tsunami is caused by a gravitational instability not amenable to earthquakes or volcanic activity, the letter G is used: GL (gravitational landslide), GS (gravitational marine slide), GA (gravitational snow avalanche). The code UN (unknown cause) is used when the tsunami cause is unknown.
Intensity: the tsunami intensity is attributed on the basis of the six-degree Sieberg-Ambraseys scale (Ambraseys, 1962). 1= very light, 2= light, 3= rather strong, 4= strong, 5= very strong, 6= disastrous.
Intensity Papadopoulos-Imamura: the tsunami intensity is attributed also on the twelve-degree Papadopoulos and Imamura (2001) scale. I= not felt, II= scarcely felt, III= weak, IV= largely observed, V= strong, VI= slightly damaging, VII= damaging, VIII= heavily damaging, IX= destructive, X= very destructive, XI= devastating, XII= completely devastating.
Run-up: maximum tsunami run-up value observed or measured, in meters. Description: a general description of the tsunami effects. In the pop-up a link to a file containing the detailed description is shown for each event.
Source parameters: the main parameters of the generating event. Source Coordinates: the geographical coordinates (Lat. And Long.) of the generating cause are reported in decimal degrees.
Earthquake Intensity: if the cause is an earthquake, the maximum macroseismic intensity (MCS scale) is reported according to bibliographical sources quoted in the description.
Earthquake Magnitude: if the cause is an earthquake, the magnitude value is given, according to bibliographical sources quoted in the description. Focal depth: if the cause is an earthquake, the focal depth (in km) is given, according to bibliographical sources quoted in the description.
VEI: if the cause is a volcanic eruption, the Volcanic Explosivity Index (VEI) of the eruption is reported, according to bibliographical sources quoted in the description. References: list of the bibliographical sources cited in the description.
