Where are most seismographs located?

Answer 1

The majority of these seismographs are anchored in seismic monitoring stations. The stations are usually set up at locations thought to be seismically active or near active faults. Seismic monitoring networks include many of such stations that function collaboratively thus facilitating the detection and recording of seismic waves result from earthquake or other relevant seismological occurrences. Such stations are usually run by governments, universities or other international organizations like USGS, EMSC or GSN which provides a detailed of the station. The locations may be different depending on the given organization, area, or country, but the scientific observations are usually performed with the stations being set on a radius to achieve the coverage of the area under monitoring.
