Seismologists require:
- The exact location of the seismometer station
- The P and S-wave arrival times as recorded on a seismometer
- Knowledge of the subsurface geology
- The same information for two other seismometer stations
Knowledge of the sub surface geology is required in order to estimate the P and S-wave velocity which is a function of the elastic modulus and density of the rock.
Please see the related question for further information on locating earthquake epicentres.
