LEKKAS, E., ANDREADAKIS, E., KOSTAKI, I., KAPOURANI, E. (2012). - A New Tsunami Intensity Scale proposed after the Tsunamis of 11 Mar. 2011, Japan & 26 Dec. 2004, Indian Ocean. 15th World Conference on Earthquake Engineering (15WCEE), Paper No. 0346, Lisbon.
The tsunami events caused by mega-earthquakes in the Indian Ocean (9.0, 12-26-04) and NE Japan (9.0, 03-11-11) had dramatic impact over extended areas and various distances from the source area, providing a huge amount of data, during unprecedented situations. The records of magnitude and grade of impact allowed a more precise specification of a more objective, 12-grade intensity scale of tsunamis, covering a full range of intensities, situations and environments. The proposed scale is based on 6 groups of criteria linking quantities, impact on all environments and human response.
