 Geophysical observatories

Geophysical observatories are scientific facilities or locations equipped with instruments and technologies to monitor and study various geophysical phenomena related to the Earth's physical properties and processes. These observatories aim to collect data on a range of parameters, including: 1. **Seismology**: Monitoring seismic activity to study earthquakes and tectonic processes. 2. **Magnetism**: Observing the Earth's magnetic field and its variations. 3. **Gravity**: Measuring gravitational changes to understand geological structures and movements.
