Seismological data

Seismological data are records of ground motion expressed in terms of displacement speed (velocimetric stations) or acceleration (accelerometric stations). The recordings come both from permanent stations enabling long-term seismicity to be monitored, and from temporary stations deployed during campaigns aimed at studying a particular area more precisely.

Since 2017 Résif (today Epos-France) has also acquired, as part of the specific SisMob action, a fleet of “node” type seismometers enabling dense sensor deployments over short periods of time.

The data portal seismology.resif.fr lets you explore the inventory of data and metadata made available by the Epos-France seismological data center. Data and metadata formats, as well as access interfaces, comply with international standards established by the Federation of Digital Seismograph Networks (FDSN).

Data managed by Epos-France follows FAIR recommendations facilitating automatic discovery, accessibility, interoperability and reusability.

This portal distributes waveforms in the standard miniSEED exchange format via webservices or rsync-type protocols for large volumes of data. Metadata are available in FDSN StationXML 1.1 format.
