Scientists and researchers can spend lots of time analysing data and I am helping with earthquake data at present. Information collected by seismometers measuring earthquake activity is accessed by computer and checked for accuracy in picking out two kinds of seismic waves - S and P waves.
During an earthquake the 2 sides of a faultline jerk past each other,releasing stored energy as seismic waves that travel out through the surrounding rock.
Seismic waves travel at different speeds - P waves are fast and reach the surface first,S waves are slower and cause the ground to shudder backwards and forwards.
It is important to record each of these separatetly - a slow job as there are thousands and thousands for each series of earthquakes!
