EARTHQUAKES make seismic waves, which seismologists use to investigate the Earth’s inner structure. Seismic waves are typically recorded on seismometers, which are instruments placed in the ground that are sensitive to the shaking of the Earth after an earthquake happens.
If there are a lot of seismometers in a certain region, seismologists are able to calculate more accurate and precise models of the Earth’s inner structure beneath.
For global models, the “resolution” of the model is a way to understand how accurate and precise it is; for regions with a lot of seismometers, the resolution is better.
