Resumen
Seismic Intensity scales are based on the effects of earthquakes on man, man-made structures and on natural environment. However, the effects on the environment have been usually minimized because they were considered as inaccurate features. The growth of Palaeoseismology as an independent discipline led to the development of the ESI-2007 Intensity Scale, based on the effects of earthquakes on the environment and ratified by INQUA during its XVII Congress (Cairns, Australia-2007). This scale can be used alone or jointly with other intensity scales, but it becomes especially useful for seismic intensity higher than X, when damage-based scales get saturated and environmental effects are still diagnostic. Tsunamis are only considered in the ESI-scale by the height of the waves, and no by their geological or sedimentary record. Data from present day tsunamis (authors’ own work and other’s published data) are used as a first approach to the implementation of this record in the ESI-scale. However, the joint effort of an international working group is desirable in order to properly match effects and intensity degrees.
