Abstract:
The exponential growth of seismic networks, at regional, continental and global levels, and the availability of online transmission of large volumes of data in near-real time, allows us to analyze the ground motion of an earthquake, of low or high magnitude, in very short times with high levels of confidence. This was the case of the recent seismic sequences in Italy (2022-11-09 Mw 5.6 Ancona) and Middle East (2023-02-06 Mw 7.8 Turkey-Syria), when thousands of researchers worldwide contributed to providing rapid analyses of seismic motion to support emergency activities and physical understanding of the observed phenomenon during the sequence.In this work, we present the new web-tool ERMES (Earthquake Reports of strong Motion EStimation) designed to create an event-report describing the characteristics of the ground motion associated with a seismic event. It is integrated with the Italian (ITACA) and the Engineering Strong Motion (ESM) databases. ERMES is developed as a tool for the analysis of the Intensity Measures soon after an event has occurred, that is reviewed and updated by expert users as new data become available and/or particular aspects of shaking need to be highlighted. In case of past events, ERMES is also useful to study the spatial distribution of the strong motion parameters.ERMES is the result of the collaborative effort of two INGV institutional tasks, namely the the INGV Seismic Hazard Center and the WP9.3 (Data and reports during the seismic emergency) of the DPC-INGV 2022-2025 Agreement.
