Contribution:
1Variation - Travel of seismic studies helped understand Earth's structure of a liquid core (as S wave doesn't have through it) → tells about layers
2Fault zones & plates - (ex: Turkey earthquake at anatolia plate thrust)
3Intensity → Mercalli's scale; Magnitude → Richter's scale ↓ helps understand seismicity
