Аннотация:Quantification of tsunami size is still under investigation since no standard magnitude scales have been established so far. Therefore, tsunami intensity is in use as a proxy of the tsunami size. Although important advances are expected from datasets from ocean-bottom tsunami recording devices, currently two methods, which follow the seismological tradition, are the most promising ones, particularly the concepts of surface wave magnitude, Ms , and moment magnitude, Mw. The tsunami magnitude by Murty and Loomis (1980) is analogous to Mw and is based on the potential source energy. Precise energy calculation, however, needs better understanding of the source mechanics. Abe’s (1989) tsunami magnitude, which is analogous to Ms , is based on tide gauge records in Japan and needs better calibration of tsunami attenuation formulas. A case study of the small tsunami caused by the October 15, 2018 earthquake (Mw6.8) in Greece has shown, for the first time, the applicability of Abe’s method in the Mediterranean Sea, which deserves further examination for the development of a regional tsunami magnitude scale.
