Global seismic network
Global Seismological Network (GSN) is a seismic research institution jointly established by the National Earthquake Information Center (USGS) of the US Geological Survey and the Joint Seismological Research Association (IRIS). The agency is committed to cooperating with the international community to install, operate and maintain multi-purpose scientific equipment for Earth observation, monitoring, research and education. The global seismic network consists of more than 150 earthquake monitors distributed all over the world, which can record earthquakes in real time and then transmit the data to satellites or networks. Finally, these data will be collected into a seismic activity database, and these data will be analyzed centrally, so as to summarize the trends and patterns before the earthquake.
The seismic detectors set up by the global seismic network around the world can measure and record the occurrence of earthquakes with high fidelity, including the influence of high-frequency strong earthquakes on surrounding earthquakes and the aftershocks caused by such earthquakes. The monitoring points of the global seismic network are mainly set up for seismological research, but these detection devices are also helpful to the research of other disciplines, and their applications tend to extend to other disciplines. Many monitoring stations of seismic network are also used to monitor and record atmospheric pressure, climate and other climatic conditions.
