Situated in two buildings located on the central campus of the University of Strasbourg, EOST consists of more than 150 permanent employees among its staff.

The classes are distributed as follows (as of 2011/2012): After the first semester of their third year, students need to complete an internship in the industry or in a research organism in order to obtain their degree.

EOST is the leader of the "laboratory of excellence" G-eau-thermie profonde project aiming to initiate a new research center for deep geothermal energy.

Improving the knowledge of deep geothermal reservoirs and developing techniques are the main goals for the exploitation of this sustainable resource.

EOST is involved in the REALISE network (Réseau Alsacien des Laboratoires en Ingénierie et Sciences de l’Environnement) and also provides leadership and administration.

Earthquakes, magnetic fields, gravity force, water chemical composition, gravitational instability are some examples of the natural phenomenon observed by EOST.

Each year, a great amount of published scientific articles are based on data collected by EOST's observational services, organized into themes: seismology, geodesy and gravimetry, magnetism, landslide processes, environment.

EOST is in charge of measuring devices localized both in the North-East of France and abroad (Sénégal, Terres Austales et Antarctiques Françaises).

EOST is responsible for 8 GPS stations located in the Rhénan area, assigned to study the tectonic strain of the North-East of France.

EOST runs six permanent magnetic stations located in the Terres Australes et Antarctiques Française and in Madagascar Island.

EOST is responsible for the Super-Sauze, La Valette (Southern Alps) and Villerville (Normandie) landslides as well as the coordination of the acquisition and the analysis of kinematics data.

The main study site of the Observatoire hydro-géochimique de l’environnement (OHGE) is a granitic catchment basin: the Strengbach.
