ARRAY SEISMOLOGY: METHODS AND APPLICATIONS

Since their development in the 1960s, seismic arrays have given a new impulse to seismology. Recordings from many uniform seismometers in a well‐defined, closely spaced configuration produce high‐quality and homogeneous data sets, which can be used to study the Earth's structure in great detail. Apart from an improvement of the signal‐to‐noise ratio due to the simple summation of the individual array recordings, seismological arrays can be used in many different ways to study the fine‐scale structure of the Earth's interior. They have helped to study such different structures as the interior of volcanos, continental crust and lithosphere, global variations of seismic velocities in the mantle, the core‐mantle…
