ISIDe: Italian Seismological Instrumental and Parametric Data-Base

Iside Logo

ISIDe data are available by this portal at:

The Italian Seismological Instrumental and Parametric Data-Base (ISIDe), version 1.0 contains the parameters of earthquake locations performed by the surveillance service of INGV Rome. It consists of hundreds thousands events occurred in the Italian region in the time frame between 01-01-1985 and today. To locate the earthquakes we used more than 500 stations of the National Seismic Network (a href="https://terremoti.ingv.it/en/instruments" alt="Instruments">https://terremoti.ingv.it/en/instruments), operated by Istituto Nazionale di Geofisica e Vulcanologia (INGV) and regional and international networks operated by several providers.

The locations are then reviewed by specialized analysts to produce the Italian Seismic Bulletin (BSI; https://terremoti.ingv.it/en/help#BSI) and updated within ISIDe. Over time the practises of the BSI changed, and also the type of magnitudes attributed by the analysts (see dedicated explanation) changed with the change in the network from analog to digital from one-component to broadband. Today only earthquakes with M>=1.5 are reviewed by the Italian Seismic Bulletin (https://terremoti.ingv.it/help#BSI) analysts.

ISIDe data can be extracted in details in Quakeml (containing uncertainties and various versions of locations and magnitudes, from automatic determinations to reviewed one), while Text, Kml and Atom formats produce simplified information in the extraction; waveforms data are available in miniseed.

Abstract:

ISIDe, the Italian Seismological Instrumental and Parametric Database, contains parameters of earthquake locations performed by the INGV surveillance service. It consists of hundreds thousands events occurred in the Italian region since January 1985. To locate earthquakes more than 500 stations of the National Seismic Network (RSN) were used, a network operated by Istituto Nazionale di Geofisica e Vulcanologia (INGV) with the contribution from other regional and international networks operated by several providers. ISIDe contains the Italian Seismic Bulletin (BSI), which reports earthquake locations and magnitudes revised by data analysts. Procedures to compile BSI evolved with time, and the type of magnitudes attributed by analysts changed as a consequence of the switch from analogue to a digital network, and from one-component to broadband stations. Nowadays analysts review earthquakes with M>=1.5 only. In addition to its web portal, ISIDe may be queried using an FDSN-event compliant web service providing detailed parameters encoded in QuakeML, an XML based format reporting uncertainties and all alternative locations and magnitudes assessed, from both automatic determinations and reviewed ones. The web service may output other, less complete, formats as well, such as plain text, KML or Atom. An FDSN-dataselect compliant web service may be used to retrieve waveforms from ISIDE that will output full SEED encoded data.
