Strength of shaking can practically be represented by peak gound acceleration (PGA), peak ground velocity (PGV), and peak ground displacement (PGD).
Earthquakes intensity magnitude and frequency
Did you know?
WebThe strength of an earthquake is generally expressed in two ways: magnitude and intensity. The magnitude is a measure that depends on the seismic energy radiated by the earthquake as recorded on seismographs. An earthquake's magnitude is expressed in whole numbers and decimals (e.g., 6.8).
