Processing web frontend - a web interface for waveform processing on ITACA database. Registered users can select waveforms, do their own processing and save the resulting waveforms on their personal computer.
dyna-convert.py - python code to convert ITACA files to the most popular seismic formats (MSEED, SAC, GSE, SEGY, among others). Requires ObsPy.
ITACA is the national layer of EPOS for the distribution of accelerometric data.
ITACA release 2.3
ITACA 2.3 contains 36714 three-component accelerometric waveforms generated by 1640 earthquakes with magnitude greater than 3 in the time frame 1972-2017, including 26096 waveforms manually processed by specialists. Data have been recorded by the National Accelerometric Network (RAN), operated by the Italian Civil Protection Department - Presidency of the Council of Ministers (DPC), the National Seismic Network, operated by Istituto Nazionale di Geofisica e Vulcanologia (INGV) and regional and international networks operated by several providers.
The major contribution to ITACA 2.3 comes from B2 2016-2017 Project (DPC-INGV Agreement 2012-2021, Obiettivo 1 - Task B) focused on site characterization. 20 new shear-wave velocity profiles, 144 noise measurements and about 300 geological maps, with different levels of detail, are now available.

This site provides access to the ITalian ACcelerometric Archive (ITACA), containing strong-motion records and associated earthquake, station and waveform parameters. The user can interactively search the fully relational database and download the selected strong-motion records and associated parameters.
The strong motion records included in the data base are devoted to qualified users. The earthquake, station and waveform parameters are obtained from the best available data. Even if all the parameters have been checked by analysts, no warranty, implicit or explicit is attached to the data. Every risk due to the improper use of data or the use of inaccurate information is assumed by the user.
In no event shall INGV (Istituto Nazionale di Geofisica e Vulcanologia) be liable to any party for direct, indirect, special, incidental, or consequential damages, including lost profits, arising out of the use of the works, even if INGV has been advised of the possibility of such damage.
The license of each waveform has been assigned by the data provider. Providers should be acknowledged according to the International Federation of Digital Seismograph Networks (FDSN).
