Environmental Seismic Intensity scale - ESI 2007 La scala di Intensità Sismica basata sugli effetti ambientali - ESI 2007
ABSTRACT - The Environmental Seismic Intensity scale (ESI 2007) is2007) is a new earthquake intensity scale only based on the effects triggered by the earthquake in the natural environment. The coseismic effects considered more diagnostic for intensity evaluation are surface faulting and tectonic uplift/subsidence (primary effects), landslides, ground cracks, liquefactions, displaced boulders, tsunami and hydrological anomalies (secondary effects). The ESI 2007 scale follows the same basic structure as any other XII degree scale, such as the MCS, MM, MSK and EMS scales. This type of intensity scale was proposed to the scientific community since the beginning of '90s. The idea was definitely accepted in 1999, when a first version of the scale was developed by a Working Group of geologists, seismologists and engineers sponsored by the International Union for Quaternary Research (INQUA). In the following years, this version has been revised and updated. The ESI 2007 scale is the result of the revision of previous versions after its application to a large number of earthquakes worldwide. In the frame of INQUA SubCommission on Paleoseismicity, this activity was conducted by academic and research institutes coordinated by the Geological Survey of Italy - APAT (for further details, s e e h t t p : / / w w w. a p a t . g o v. i t / s i t e / e n - GB/Projects/INQUA_Scale/default.html). For intensity levels lower than IX, the main goal of this new scale is to bring the environmental effects in line with the damage indicators. In this range, the ESI 2007 scale should be used along with the other scales. In the range between X and XII, the distribution and size of environmental effects, specially primary tectonic features, becomes the most diagnostic tool to assess the intensity level. Documentary report and/or field observations on fault rupture length and surface displacement should be consistently implemented in the macroseismic study of past and future earthquakes. Therefore, the use of the ESI 2007 alone is recommended only when effects on humans and on manmade structures i) are absent, or too scarce (i.e. in sparsely populated or desert areas), and ii) saturate (i.e., for intensity X to XII) loosing their diagnostic value. After its official approval at the 17th INQUA Congress, the use of the ESI 2007 scale will be proposed to national institutions (geological surveys, academic and research institutes, departments for civil protection, environmental agencies, etc.), dealing in the field of earthquake intensity and seismic hazar

Earthquake Hazard and the Environmental Seismic Intensity (ESI) Scale
The main objective of this paper was to introduce the Environmental Seismic Intensity scale (ESI), a new scale
developed and tested by an interdisciplinary group of scientists (geologists, geophysicists and seismologists) in the frame of the
International Union for Quaternary Research (INQUA) activities, to the widest community of earth scientists and engineers dealing
with seismic hazard assessment. This scale defines earthquake intensity by taking into consideration the occurrence, size and areal
distribution of earthquake environmental effects (EEE), including surface faulting, tectonic uplift and subsidence, landslides, rock
falls, liquefaction, ground collapse and tsunami waves. Indeed, EEEs can significantly improve the evaluation of seismic intensity,
which still remains a critical parameter for a realistic seismic hazard assessment, allowing to compare historical and modern
earthquakes. Moreover, as shown by recent moderate to large earthquakes, geological effects often cause severe damage\u2019\u2019;
therefore, their consideration in the earthquake risk scenario is crucial for all stakeholders, especially urban planners, geotechnical
and structural engineers, hazard analysts, civil protection agencies and insurance companies. The paper describes background and
construction principles of the scale and presents some case studies in different continents and tectonic settings to illustrate its relevant
benefits. ESI is normally used together with traditional intensity scales, which, unfortunately, tend to saturate in the highest degrees.
In this case and in unpopulated areas, ESI offers a unique way for assessing a reliable earthquake intensity. Finally, yet importantly,
the ESI scale also provides a very convenient guideline for the survey of EEEs in earthquake-stricken areas, ensuring they are
catalogued in a complete and homogeneous manner
