Global Station Networks

Our global measurement networks are a key tool for understanding the Earth system. Among other things, we want to identify and analyse natural hazards and observe the effects of global climate change. The global monitoring networks are modules of the Modular Earth Science Infrastructure (MESI).
GE Seismic Network - GEOFON Global Seismic Network
In 2018 the GEOFON global seismic network consists of more than 80 active high quality stations with real-time acquisition. The network plays a leading role in global real-time seismology providing valuable data for almost all fundamental and applie…
Geomagnetic Observatory Niemegk (NGK)
The Adolf-Schmidt-Observatory for Geomagnetism in Niemegk is operated by GFZ since 1992. It belongs to Section 2.3, Geomagnetism. The observatory is located 50km SW of Potsdam. Since 1930 it continues the measurements, that started in Potsdam in 189…
HELGOG - Helgoland Gravimetric Observatory Germany
The Helgoland Gravimetric Observatory Germany (HELGOG) was established in March 2020 in the basement of the Biologische Anstalt Helgoland (BAH) of the Alfred Wegener Institute AWI, Helmholtz Centre for Polar and Marine Research. The main research fo…
Permanent Magnetotelluric Reference Station in Wittstock, Germany
The sources for the magnetotelluric (MT) method are naturally occurring electromagnetic field variations. Electromagnetic currents are excited over a wide frequency range in the earth’s ionosphere by solar activity and global lighting discharges. Wh…
SAGOS - South African Geodynamic Observatory Sutherland
The South African Geodynamic Observatory Sutherland (SAGOS) of GFZ was established during the years 1998 – 2000 based on an Agreement on Cooperative Activities between the National Research Foundation (NRF) and GFZ, signed in August 1998. SAGOS is l…
