User advice

This is a "static" version of a former ITACA database, mantained only for historical and reference purposes.

Each ITACA version is periodically revised by specialists to detect errors and inconsistencies improving data and metadata quality. Therefore, it is recommended to use the latest ITACA version which includes up to date information and provides an user friendly interface to query the database for data and metadata access.

ITACA 2.1 (released January 2016)

ITACA 2.1 contains 25222 three-component accelerometric waveforms generated by 1365 earthquakes with magnitude greater than 3 in the time frame 1972-2015, including 14801 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 ITACA portal allows users to query earthquake and station information and ground motion parameters, and to select and download accelerometric (processed and unprocessed) waveforms and response spectra upon user registration. The metadata relative to seismic events and recording stations are revised on a yearly basis according to authoritative sources. Events after December 31st 2015 with magnitude greater than 4 are available at the European Strong-Motion database.

Events after December 31st 2015 with magnitude greater than 4 are available at the Engineering Strong-Motion database.

ITACA is particularly targeted for:

  • - seismologists and strong-motion data analysts;
  • - earthquake and geotechnical engineers;
  • - national agencies;
  • - students and professionals, if adequately trained.

ITACA 2.1 has been compiled under the co-ordination of INGV Milano, thanks to the following contribution:

  1. 1) Agreement between INGV and DPC (2012-2021);

  2. 2) S2 project (2014-2015) in the framework of the agreement INGV-DPC.

ITACA is the national layer of EPOS for the distribution of accelerometric data.

Tools
