These three observatories are responsible for alerting civil protection authorities when abnormal activity is recorded. For that, they operate and maintain networks of permanent instruments to eventually proccess and analyse data acquired continuously.

The main goal of the VOLOBSIS portal is to distribute to the national and international communities the data acquired by the IPGP Volcanological and Seismological Observatories.

The geophysical and geochemical data are available after a delay required for their validation and transmission to the database in the IPGP Data Center. The date of the most recent data available varies according data type. The real-time data are available as detailed in the "Data Description" part of the portal.
