From the analysis of the information available in EMTC2.0 on the effects of tsunamis observed along the Italian coasts, ITED - Italian Tsunami Effects Database has been developed. The main purpose of ITED is to make tsunami data of the Italian area more easily accessible, ITED provides details on the effects of tsunamis observed/measured in different Observation Points (OP) geographically located along the coasts. In some cases, when the OPs cannot be associated with a point of known coordinates, the coordinates of the nearest known location, called Place Name (PN), are reported. When effect descriptions are very detailed, it is possible to identify multiple observation points (OPs) related to the same PN. 

The ITED WebApp contains six layers with information related to all the tsunami effects observed on the Italian coasts and has been developed using the Esri ArcGIS online environment.

Currently ITED contains 318 observation points (OPs) referring to 189 PNs and reports both descriptive and quantitative information on tsunami effects. For each OP the user can retrieve the description of the effects and quantitative data (local intensity, run-up, inundation, sea retreat, etc.), all accompanied by the respective bibliographic references. Based on the description,tsunami local intensity was assessed at each observation point , according to the Sieberg-Ambraseys and Papadopoulos-Imamura scales (Papadopoulos and Imamura, 2001). ITED also allows to know the "intensity map" of each event, i.e. to visualize all the POs related to a single tsunami, with their local intensity. For each PN, the distribution of tsunami intensities over time (tsunami history) is available. Among the 189 NPs included in the database, 51 have experienced tsunami effects more than once.

In order to have a complete collection of the effects of tsunamis observed along the Italian coasts, in ITED were also taken into account four events generated outside the Italian territory which produced effects on Italian coasts. Three of them originated in the seas of Greece and one off the coast of Algeria. ITED is interconnected with EMTC2.0 and the WebApp allows to select the two layers simultaneously. 

ITED data can be downloaded through the following web services OGC WFS (Open Geospatial Consortium Web Feature Service) and OGC WMS (Open Geospatial Consortium Web Map Service)
