# Historical Information — SeisComP Release documentation

6.9.0

# Historical Information

The first version of SeisComP was developed for the GEOFON program operated by GFZ.

Originally, SeisComP was designed as a high-standard, fully automatic data acquisition and (near-)real-time data processing tool including quality control, event detection and location as well as dissemination of event alerts.

SeisComP was further extended within the MEREDIAN project under the lead of GEOFON and Orfeus [19].

Following the devastating 2004 Indian Ocean earthquake and tsunami, the GITEWS [10] (German Indian Ocean Tsunami Early Warning System) project led to additional functionality being implemented to fulfill the requirements of 24/7 early warning control centers. Major changes in the architecture of SeisComP were necessary and many new features resulted in the upgrade of SeisComP to version 3.

Since 2008 SeisComP has been jointly developed by gempa GmbH, a spin-off company of GFZ and GFZ. Nowadays, gempa GmbH is the main SeisComP developing and service company.

Major SeisComP releases are shown below. The important changes as of version 4.0 are documented in the changelog.
